The importance of product processing technology
The process of the internal structure of the product is closely related to the processing cost. The processing technology used by the product directly determines the production cost, and the processing efficiency and production capacity will also be affected by it.
From the perspective of product design, if the manufacturing threshold of processing technology can be fundamentally reduced, on this basis, certain processing costs can be reduced, and the processing CT time of CNC machine tools can be shortened, and the processing quality and processing quality can be improved. Efficiency can be improved. Can greatly improve the CNC machining capacity.

Tool life management control in CNC machining
The life management control of the tool by the CNC system is to calculate the number of tool machining, or to determine the processing time. Therefore, when the tool life reaches the expected number of machining times or time of the system, the CNC automatically stops the action. It is assumed that when manual supervision is not in place, or when the tool is not able to stop changing in the expected situation, the CNC machining process will be affected. Therefore, tool life is a key factor affecting CNC production capacity.
Especially when the CNC machining process of a workpiece is too much, the processing amount is cumbersome, and the dimensional accuracy of the processing is relatively strict, the tools to be used will be more. At this time, the CNC tool library automatically changes the tool, and the knife action is more frequent, and the tool wear is larger, so that the manual tool change and machine adjustment are more frequent.
Therefore, tool wear is an important indicator that affects the normal production rhythm and capacity of CNC. Through technical measures to improve the process, improve the overall life of the tool, not only can save the cost of the tool, but more importantly, can reduce the stopping time of the CNC spindle, so as to improve the efficiency of CNC processing, improve the production quality and capacity.

CNC machining process improvement
When writing CNC machining process, it is not only necessary to focus on the feasibility of processing, but also to consider whether the process of the processing process will have a negative effect on the processing efficiency. Effectively shorten the processing time of CNC CT and improve production capacity can be achieved by arranging a reasonable processing sequence and reducing the number of tool changes.

The production site is strictly controlled
The development and strict implementation of production SOP is an indispensable part of CNC machining production process. Manual operation behavior should be reasonably standardized to reduce employees' negative emotions and unnecessary waste of time efficiency. Formulate incentive policies to improve the enthusiasm of technicians, so as to achieve the purpose of improving production capacity and product processing quality.

CNC machining abnormal problem elimination
The inspection work needs to be comprehensive, such as the use of the cylinder, solenoid valve, motor and other electrical parts in the oil environment on the equipment and fixture condition, and the investigation of these parts before the operation can effectively avoid the situation that the production of CNC spindle is forced to stop, so as to improve the utilization rate of the spindle.
Machine iteration is expensive, but there are other methods we can use to do it at a very small cost in exchange for a high yield.
The high-quality management of CNC machining production should be put in the first place, and the above six points can effectively improve the production performance and capacity of the machine tool.
Six industries that rely on cnc machining
Modern CNC (computer numerical control) machines enable the manufacture of precision parts quickly and efficiently. CNC machines manufacture millions of parts around the world every day. All of these parts vary in size, material and purpose.
CNC machining is often used for metal parts and assemblies with complex designs and tight tolerances. Because of the precision and capability of CNC machining, it is one of the most demanding manufacturing methods.
These industries rely heavily on CNC machined parts: automotive, Aerospace & Defense, medical, construction equipment, Power & Energy, and industrial. In this article, we will share how each industry uses precision machined parts.
Automobile industry
The automotive and transportation industry is one of the largest users of CNC machined parts. Cars, trucks, vans and motorcycles all use precision metal parts. Vehicles require thousands of parts, which require high precision and durability.
CNC machining is ideal for many automotive parts because the parts need to be the same and made of hard metals such as steel and stainless steel. Many engine and transmission parts are CNC machined. Few manufacturing processes can match the precision and repeatability offered by CNC machining.
Electric vehicles play an important role in the development of CNC machining, as they require a large number of precision-machined parts.
Medical industry
Similar to the automotive industry, the medical industry requires parts with extremely tight tolerances. There is no room for error in the manufacture of life-saving equipment.
CNC machining provides the medical industry with precision parts, required materials, and fast manufacturing. CNC machines can use specific materials required by the medical industry, such as stainless steel, titanium and copper parts.
CNC machining is also an ideal choice to support crisis response. In early 2020, many CNC workshops shifted part of their work to manufacturing basic medical equipment such as parts for ventilators. CNC machines have a wide range of functions and can be easily programmed to make new parts.
Industrial equipment industry
CNC machines make parts for other manufacturing operations. The industrial sector includes packaging equipment, electronics and other general industrial equipment. Overall, the industry accounts for about 25% of CNC machined parts.
Industrial equipment often requires high-precision parts that can operate in high-stress environments. The consistency and custom machining capabilities offered by CNC machining are necessary for the industry.
Aerospace and defense industries
The aerospace industry is worth an estimated $300 billion and shows no signs of slowing down. We usually think of aerospace as = airplanes, but there are also thousands of satellites and rockets that require thousands of precision parts.
The aerospace and defense industry relies on CNC machining to manufacture complex precision parts that leave no margin for error. The tight tolerances, rapid prototyping and scalability of CNC machines are ideally suited to meet the needs of this industry.
Construction industry
The construction industry needs reliable, high-strength parts that can operate in harsh environments. CNC machine tools can process large and small metal parts needed for construction equipment.
CNC machining is the best manufacturing method for difficult metal alloys. High-strength steel alloys are commonly used to make parts for cranes, lifting equipment, bulldozers and other construction equipment. Gears, pump equipment, and high-strength fasteners are just a few examples of NC machined parts.
Energy industry
The gas, oil and energy industry is another huge market that relies on many #CNC machined components. Precision valves, bushings and sensor devices all require precision machined parts.
To keep vital energy infrastructure operating at peak efficiency, components need to fit perfectly together.
Parts used in harsh environments require high precision and high corrosion and heat resistance. Salt water and chemicals can destroy many metal parts, so the industry needs metals such as Hastelloy, which often require modern CNC machine tool cutting tools.
In general, CNC machining process plays an irreplaceable role in modern manufacturing industry, and its high precision, high efficiency and flexibility bring great development opportunities and competitive advantages to all walks of life. With the continuous progress of technology and the continuous expansion of applications, CNC machining technology will continue to play an important role in the future manufacturing industry, and make new contributions to the progress and development of human society.#Honscn #cnc

1 Tool change of hat type magazineThe fixed address tool change mode is mostly adopted, and the tool number is fixed corresponding to the tool seat number. The tool change action is realized by the lateral movement of the tool magazine and the up and down movement of the spindle, which is referred to as the spindle tool change mode for short. Because it has no tool change manipulator, the tool selection action cannot be preselected before the tool change action. The tool change instruction and tool selection instruction are generally written in the same program segment, and the instruction format is as follows:M06 T
When the command is executed, the tool magazine first turns the tool holder corresponding to the tool number on the spindle to the tool change position, and switches the tool on the spindle back to the tool holder, and then the tool magazine turns the tool specified in the command to the tool change position and changes the spindle.For this tool magazine, even if TX x is executed before M06, the tool cannot be preselected, * the action of final tool selection is still executed when M06 is executed. If there is no TX X in front of M06, the system will give an alarm.2 Tool change of disc and chain magazine
Most of them use random address tool change mode. The corresponding relationship between tool number and tool seat number is random, but its corresponding relationship can be remembered by NC system. The tool change of this tool magazine depends on the manipulator. The action of the command and tool change is: the tool command TX controls the rotation of the tool magazine and turns the selected tool to the tool change working position, while the tool change command M06 controls the action of the tool change manipulator to realize the tool exchange between the spindle tool and the tool change position of the tool magazine. The tool selection command and tool change command can be in the same program segment or written separately. The actions corresponding to tool selection and tool change command can also be operated simultaneously or separately. The instruction format is as follows:
Tx x M06;When the command is executed, the tool magazine first turns the TX tool to the tool change position, and then the manipulator exchanges the tool of the tool magazine with the tool of the spindle to realize the purpose of changing the TX tool to the spindle.After reading the above two methods, it can be seen that method 2 overlaps the tool selection action with the machining action, so that when changing the tool, it is not necessary to select the tool and change the tool directly, which improves the work efficiency.
As mentioned earlier, the tool change command of the tool magazine is related to the machine tool manufacturer. For example, some tool magazines require that not only the Z axis must return to the tool change point, but also the Y axis must return to the tool change point. The program format is as follows:
When writing the instructions of tool selection and tool change in the same program section, the execution rules of tools from different manufacturers may also be different. If any, regardless of the writing order, the rules of tool selection and tool change shall be followed. Some rules stipulate that the tool selection command must be written before the tool change command is executed. Otherwise, the action is to change the tool first and then select the tool, as shown in the above program. In this case, if the tool selection command is not written before the M06 command is executed, the system will give an alarm.
When the command is executed, the tool magazine first turns the tool holder corresponding to the tool number on the spindle to the tool change position, and switches the tool on the spindle back to the tool holder, and then the tool magazine turns the tool specified in the command to the tool change position and changes the spindle.For this tool magazine, even if TX x is executed before M06, the tool cannot be preselected, * the action of final tool selection is still executed when M06 is executed.

The requirements of lightweight, safety and decoration in modern automobile manufacturing industry drive the development of traditional welding technology in the field of automobile plastics. In recent years, with the application of a variety of high-end technologies such as ultrasonic, vibration friction and laser technology in the field of automobile plastic parts manufacturing, the technical level and supporting capacity of domestic automobile parts manufacturing industry have been greatly improved.As for the welding and welding process of automotive interior parts, hot plate welding, laser welding, ultrasonic welding, non-standard ultrasonic welding machine, vibration friction machine, etc. have been developed. In the process, one-time overall or complex structure welding can be realized, and the optimal design requirements can be achieved on the basis of simplifying mold design and reducing molding cost.For typical interior and exterior trim parts, large components with high surface quality and complex structure, such as instrument panel, door panel, column, glove box, engine intake manifold, front and rear bumper, must select corresponding welding technology, and adopt appropriate welding process according to the requirements of interior structure, performance, materials and production cost. All these applications can not only complete the corresponding manufacturing process, but also ensure the excellent quality and perfect shape of products.
Hot plate welding machine: the hot plate welding machine equipment can control the horizontal or vertical movement of the hot plate welding die, and the transmission system is driven by pneumatic, hydraulic drive or servo motor. The advantages of hot plate welding technology are that it can be applied to workpieces of different sizes without area limitation, applicable to any welding surface, allowing plastic allowance compensation, ensuring welding strength, and adjusting welding procedures according to the needs of various materials (such as adjusting welding temperature, welding time, cooling time, input air pressure, welding temperature and switching time, etc.), In the welding process, the equipment can maintain good stability, ensure consistent welding effect and accuracy of workpiece height after machining.
Another feature of the horizontal hot plate welding machine is that it can rotate at 90 for cleaning. The processing period of hot plate welding machine can generally be divided into: original position (the hot plate does not move with the upper and lower molds), heating period (the hot plate moves between the upper and lower molds, and the heat of the hot plate moves down the upper and lower molds to dissolve the welding surfaces of the upper and lower workpieces), transfer period (the upper and lower molds return to the original position, and the hot plate exits), welding and cooling period (the upper and lower dies are joined to make the workpiece welded at the same time and cooled for forming), and return to the original position (the upper and lower dies are separated, and the welded workpiece can be taken out).
In the early automobile industry, these welding equipment were relatively common, but with the continuous improvement of the requirements for the structure, shape and service life of the parts themselves, the requirements for their processing equipment are higher and higher. Moreover, because the size of the equipment is limited to the size of the welded parts, the equipment and equipment driving mode should be selected according to the size of the parts in the design. The most important thing is the parts The heating area is large and there is large deformation. In addition, the welding process distinguishes the polarity and non polarity of welding plastics, resulting in the gradual replacement of hot plate welding by ultrasonic welding and laser welding. The main parts used for welding in China include automotive plastic fuel tank, battery, tail lamp, glove box, etc.
Laser welding: laser welding technology is widely used in today's medical device manufacturing industry. Only a few manufacturers in the automotive industry use laser welding air inlet pipe, etc. because it is a new welding technology, it is not very mature to a certain extent, but it is believed that it will be widely used in the near future because of its remarkable welding characteristics. Its advantage is that it can weld TPE / TP Or TPE products; under the condition of no vibration, nylon, workpiece with sensitive electronic parts and three-dimensional welding surface can be welded, which can save cost and reduce waste products.
In the welding process, the resin melts less, the surface can be welded tightly, and there is no flash or glue overflow. It is allowed that rigid plastic parts can be welded without glue overflow and vibration. Generally, workpieces with soft or irregular welding surfaces can be welded evenly regardless of the size of workpieces, especially for large-scale production of high-tech micro parts. However, laser conduction is limited. "Quasi synchronous" laser welding technology uses a scanning mirror to transmit the laser beam to the welding surface at the speed of 10m / s according to the welding shape. It can walk on the welding surface as many as 40 times in 1s. The plastic around the welding surface melts and the two workpieces are welded after pressurization.
Laser welding can be roughly divided into: solid Nd-YAG system (laser beam is generated by crystal) and diodesystem (high power diode laser) , CAD data programming. All materials can be laser welded with body materials, among which acrylonitrile butadiene styrene is most suitable for laser welding with other materials, nylon, polypropylene and polyethylene can only be welded with their own body materials, and other materials have general applicability for laser welding.fqj

It is said that in the career of a machine tool worker, no matter how careful it is, it is impossible to avoid a knife collision accident.This has nothing to do with whether the worker is serious and practical and stable, just like a person can not avoid mistakes in the growth process, in the growth process of a machine tool worker, the knife seems to be a hurdle that cannot be bypassing.
Bumping tool, refers to the tool in the process of moving with the workpiece, chuck or tailstock accidental collision machine accident, is the most likely accident for CNC lathe operation novices.
Knife collision will cause workpiece scrap, tool damage, serious damage to the accuracy of the machine tool, destroy the machine parts, and even endanger the personal safety of the machine tool processing personnel.
The occurrence of knife collision accidents is mainly caused by programming errors in the programming process or workers' operational errors in the processing link.
For workers, the general programming link is not easy to make mistakes, and many people have knife collision accidents, often caused by mistakes in the process of machine tool operation.
Because the CNC machining center is locked by software, in the simulation processing, when the automatic operation button is pressed, it is not intuitive to see whether the machine is locked in the simulation interface.
There is often no tool in the simulation, and if the machine tool is not locked to run, it is easy to bump the knife.
Therefore, before the simulation processing should go to the running interface to confirm whether the machine is locked.
Why do CNC machining centers bump knives?
1. Forget to turn off the empty running switch during processing.
Because in the program simulation, in order to save time, the empty run switch is often turned on.
Empty operation means that all moving axes of the machine are running at the speed of G00.
If the operation switch is not turned off during the processing time, the machine tool ignores the given feed speed, and runs at the speed of G00, resulting in knife and machine tool accidents.
2. No reference point is returned after running the simulation empty.
In the verification program when the machine is locked motionless, and the tool relative to the workpiece processing in the simulation operation (absolute coordinates and relative coordinates change), then the coordinates do not match the actual position, must use the method of returning the reference point to ensure that the mechanical zero coordinates are consistent with the absolute and relative coordinates.
If the machining operation is carried out without finding the problem after the verification procedure, it will cause the collision of the tool.
3. The direction of overshoot release is not correct.
When the machine overruns, it should press and hold the overruns release button, and move in the opposite direction manually or by hand, that is, it can be eliminated.
However, if the direction of lifting is reversed, it will cause damage to the machine tool.
Because when the overrange release is pressed, the overrange protection of the machine tool will not work, and the stroke switch of the overrange protection is already at the end of the stroke.
At this time, it is possible to cause the workbench to continue to move in the direction of excess, and eventually pull the lead screw, causing damage to the machine tool.
4. The cursor position of the specified line is incorrect.
When a specified line is run, it is usually executed downward from the cursor position.
For the lathe, it is necessary to call the tool offset value of the tool used, if the tool is not called, the tool running the program segment may not be the desired tool, and it is very likely to cause a collision accident due to different tools.
Of course, in the machining center, CNC milling machine must first call the coordinate system such as G54 and the length compensation value of the knife.
Because the length compensation value of each knife is not the same, it is possible to cause knife collision if it is not called.
As a high-precision machine tool, anti-collision is very necessary, requiring the operator to develop the habit of being careful and careful, operating the machine tool according to the correct method, and reducing the occurrence of machine tool collision.
With the development of technology, advanced technologies such as tool damage detection, machine tool anti-impact detection, and machine tool adaptive processing have emerged during processing, which can better protect CNC machine tools.
There are 9 reasons for this:
(1) Programming error
The process arrangement is wrong, the process undertaking relationship is not carefully considered, and the parameter setting is wrong.
Example :
A. The coordinate is set to zero at the base, but the top is 0 in practice;
B. The safety height is too low, resulting in the tool can not completely lift out the workpiece;
C. The second opening margin is less than the previous knife;
D. After the program is written, the path of the program should be analyzed and checked;
(2) Program single remarks error
Example:
A. The number of unilateral touches is written in four sides;
B. The clamping distance of the vise or the protruding distance of the workpiece is wrong;
C. The extension length of the tool is unknown or wrong, resulting in knife collision;
D. Procedure sheet should be as detailed as possible;
E. The principle of new for old should be adopted when the procedure is changed:Destroy the old program.
(3) Tool measurement error
Example:
A. The tool bar is not considered in the tool data input;
B. The tool is too short;
C. Tool measurement should use scientific methods, as far as possible with more accurate instruments;
D. The length of the tool should be 2-5mm longer than the actual depth.
(4) Program transmission error
Program number call error or program modification, but still use the old program processing; The site processor must check the detailed data of the program before processing; For example, the time and date the program was written and simulated with bear.
(5) Wrong knife selection
(6) the blank exceeds expectations, and the blank is too large and does not conform to the blank set by the program
(7) The workpiece material itself has defects or high hardness
(8) clamping factors, pad interference and the procedure is not considered
(9) Machine tool failure, sudden power failure, lightning strike caused tool collision, etc
