Application of CMM

Three-coordinate measuring instrument, also known as three-dimensional measuring machine or three-dimensional measuring instrument, has become an important means of design, development, manufacturing and quality assurance in the modern manufacturing industry, especially the mold industry, with its high precision, high flexibility and excellent digital capabilities. The three-coordinate measuring instrument plays two important roles in the mold industry.

First, the three-coordinate measuring instrument can provide quality assurance for the mold industry, and is the best choice for mold manufacturing enterprises to measure and inspect. The CMM's flexibility in handling different jobs combined with its own high precision makes it an arbiter. While providing dimensional data for process control, the three-coordinate measuring instrument can provide additional functions such as incoming product inspection, customer quality inspection, gauge inspection, and mold workpiece inspection. The highly flexible three-coordinate measuring instrument can be configured in the workshop environment and directly participate in each stage of mold processing, assembly, mold trial and mold repair, providing necessary detection feedback, reducing the number of rework and shortening the mold development cycle, thereby ultimately reducing The manufacturing cost of the mold and bring the production into control.

Second, the three-coordinate measuring instrument has powerful reverse engineering capabilities and is an ideal digital tool. Through the combination of the three-coordinate measuring machine probe and three-coordinate measuring machines with different structures, the three-dimensional data and geometric features of the workpiece surface can be quickly and accurately obtained, which is especially useful for mold design, sample replication, and repair of damaged molds . In addition, the contact scanning probe of the three-coordinate measuring machine, using the powerful scanning function provided by the measurement software, can complete the replication of the complex workpiece CAD model with free-form surface shape features. Without any conversion, it can be directly recognized and programmed by various CAD software, thus greatly improving the efficiency of mold design.

Specifically, when using a three-coordinate measuring instrument in a mold manufacturing enterprise to complete design and inspection tasks, it is necessary to pay close attention to the selection of measurement benchmarks, the calibration and selection of probes, the planning of the number of measurement points and measurement locations, the establishment of coordinate systems, and the environment. influence of many factors. Each of these factors is enough to affect the accuracy and efficiency of the measurement results. The application of three-coordinate measuring instruments in mold production is already imminent, and some mold designs require the use of three-coordinate measuring instruments. It can greatly improve the design efficiency of the mold, and the accuracy will also be greatly improved.
