The development and application of three coordinate image measuring instrument

Automatic image Measuring Instrument is divided into traditional contact coordinate measuring machine and three coordinate measuring instrument. What is their development process?

Traditional coordinate measurement refers to contact coordinate measuring machine, which realizes automatic measurement by touching products with probes. It has the advantages of automatic measurement, reducing human errors, programming large size products and realizing batch measurement. However, the problem is that the contact measurement can only be performed on the surface, and the geometric entities such as column, cone, ball, etc., and the probe must be selected according to the size of the feature to be measured. Before use, it can be used after calibration.

In the automatic operation of the contact CMM, the image measuring instrument must be touched bit by bit. The process of approaching, touching and bouncing is not only time-consuming, but also must have a safe space before use. The Z minor diameter of the probe is 0.3 mm or less, which is difficult to program and the probe is prone to collision. Then, thin-walled and easily deformed products are more difficult to touch.

With the development of digital precision and micro manufacturing, the trend of product integration, the rapid and high-precision measurement of micro products have become an increasingly urgent task in the industry. Contact CMM can realize automatic measurement, which can not fully meet the requirements. With the development and high integration of optical, mechanical and electronic technologies, three coordinate measuring instruments and multi-sensor three-dimensional optical measuring instruments have emerged.

OGP's 3D optical measuring instrument can be used to measure the geometric tolerance of various materials, colors, transparent or translucent parts, from 200mm to 2000mm, and the measurement accuracy is from 2um to 4um. You do not need to worry about the size of the measured value, because in the automatic program, the magnification can be changed as needed. You don't have to worry about positioning. The product boundary is too complex or requires a lot of measurement, because the powerful image analysis function of OGP 3D measurement software can avoid easily distinguishing fine edges and achieve accurate measurement of products in batches.

Just add a multi-sensor to the OGP Smartscope, and you can see that the operation of the multi-sensor measurement program is full of praise and surprise. Optics After quickly executing all 3D geometric dimensions and geometric tolerances, the measurement software automatically calls the laser, turntable, probe, etc., or rotates the five axis coordinate system, or scans a small area, or conducts a single touch measurement;
OGP's unique feather probe and micro detection technology can complete measurement without touching or using under image. The use of remote laser breaks through the measurement limit of traditional triangular laser, and can complete deep holes within 200 mm working distance. And measure the blind hole. A variety of measurement methods and powerful measurement functions will be perfectly presented in your product measurement program, and it is difficult to measure problems. It will be handed over to the OGP Smartscope team to help you.
