The important role of CMM in the CNC machining industry

by:Yifeng Metal     2022-03-02
The coordinate measuring machine (CMM) is widely used in the CNC machining industry. It is a modern intelligent tool for design, development, testing, and statistical analysis. It is an effective tool for mold technology to ensure unparalleled quality.
If there is a deviation in the core cavity matched with the guide post and guide sleeve, the deviation can be found to correct the CMM. After the mold cavity contour is processed and formed, many inserts and local surfaces are formed on the CNC EDM machine through the electrode, so the substandard machining quality and surface quality of the electrode become the key to quality. Therefore, it is essential to measure the electrode shape with a CMM.

CMM can apply 3D model input to produce mold and mold orientation, size, shape and position tolerance, measure curve and surface, and output graphic report, which can directly and clearly reflect the quality, so as to form a complete mold product Test Report. Some molds have been worn for a period of time and must be modified, but in the absence of the original design data (model), the cross-section can be used to collect point clouds, adopt the specified format, and perform probe radius compensation after modeling, so as to achieve a complete effect.



When some surface profiles are neither circular nor parabola, but some irregular surfaces, the surface of the hand-made clay or plaster can be used as the end of the embryo. Then measure each line of the CMM, the characteristics and classification of the line, adopt the prescribed format, go through the probe radius compensation model, the smooth curve in the molding process, and design and manufacture a new mold.






The measuring machine provides quality assurance for the mold industry and is the best choice for mold manufacturing enterprises to measure and test. Measure the flexibility of handling different tasks as well as their high precision, becoming the arbiter. While providing dimensional data for process control, measuring machine products are available for additional capabilities such as testing, machine calibration, customer, quality certification, metrology, inspection, process testing and optimizing machine settings.



The highly flexible CMM can be configured in the workshop environment, directly participating in all stages of processing, assembly, testing, and maintenance, providing necessary test feedback, reducing rework, and shortening the development cycle. The measuring machine has strong reverse engineering capabilities , is an ideal digital tool. Through the combination of different types of probes and structural shape measuring machines, the data and geometry of the workpiece surface can be obtained quickly and accurately, which is especially useful for mold design, sample replication, damage, and mold repair.



In addition, the measuring machine can also be equipped with contact and non-contact scanning probes, and use PC-DMIS software to provide powerful scanning functions to complete the replication of complex work CAD modeling free-form features. Without any conversion, it can be directly identified through various CAD software and programming, which greatly improves the design efficiency.
