Comparative Analysis of Cost Between 3D Scanning and Mapping of Artificial Mechanical Parts

Project introduction

Customer products

This product is a mechanical part, and the processing structure is complex, so the size and relative position requirements are high. Therefore, the accessory needs to scan the data of the first industrial part in 3D, detect the quality error between the data and the design document, and analyze the mapping cost of mechanical parts to ensure the smooth progress of production.

Customer difficulties

After the customer's castings are processed, how to detect them has become a difficult problem. The customer has no way to detect the complex structure, many internal dimensions, important processing positions and relative positions.

The customer recognizes that the measuring equipment

The customer learned about our hand-held 3D laser scanner of Nanjing Ningrui metrology through the introduction of a friend, and checked the relevant knowledge on the Internet. He thought it was too suitable for the mapping of mechanical parts they wanted, so he found us.

Introduction to 3D laser scanner

When the portable 3D scanner T-scan works, the six beam laser is used to obtain the three-dimensional point cloud on the object surface. The operator can hold the equipment in his hand and adjust the distance and angle between the instrument and the measured object in real time. The operation is flexible, convenient and easy to learn. When scanning large volume objects, it can cooperate with the global photogrammetry system to eliminate the cumulative error and scan the size, shape and working environment of the scanned objects efficiently and accurately.

Solution

The hand-held three-dimensional scanner is a mechanical mapping equipment. Firstly, the positioning mark points should be quickly pasted on the scanned products, and then the three-dimensional data of workpiece surface shape can be obtained quickly and accurately by using the mark points pasted on the workpiece surface through non-contact three-dimensional laser scanning; After the scanner obtains the high-precision data, the obtained data is compared with the existing digital analog, so as to obtain the product deviation and carry out cost analysis.

Scanning process

  It takes 7 minutes to paste the marked points;

  Data post-processing and comparison for 45 minutes.

summary

The grooved parts of the rotor body in the machine conform to the fit of the rotor gear and change the old comparison method. The use of 3D laser scanner is not only convenient and fast, but also can more accurately grasp the accuracy of each position, which brings better service to customers.
