Modern manufacturing is moving at a breakneck pace, and that means the old ways of checking parts just aren’t cutting it anymore for high-stakes quality control. To keep production errors low and maintain the kind of quality standards that clients expect, factories now have to rely on sophisticated dimensional inspection tools that don’t blink.<\/span><\/p>\n

The <\/span>coordinate measuring machine<\/b> (CMM) has long been the gold-standard tool for this job, giving engineers a way to verify every curve and angle of a part. The <\/span>optical CMM<\/b> system has emerged as a revolutionary measurement tool because it uses non-contact technology to achieve faster operations while maintaining precise measurement accuracy.\u00a0<\/span><\/p>\n

What is a Coordinate Measuring Machine (CMM)?<\/b><\/h2>\n

A <\/span>coordinate measuring machine<\/b><\/a> functions as a highly accurate digital ruler, which enables users to create precise three-dimensional models of any physical object. The measurement tools perform essential functions which enable technicians to obtain 3D coordinates and dimensions of physical objects through precise measurement of total length, hole diameters, and complex angles.<\/span><\/p>\n

The way it works is fairly simple. It uses a sensitive probe or sensor to tap or scan points across the surface of a physical component. Once those points are collected, the software builds a complete map of the dimensional data so you can see if the part matches your original design.<\/span><\/p>\n

You will usually find a <\/span>CMM machine<\/b> sitting in a temperature-controlled quality lab or in the factories to catch mistakes before parts are shipped out. Having a reliable <\/span>precision measurement system<\/b> on-site means your work meets the strict requirements of your customers.<\/span><\/p>\n

What is an Optical CMM?<\/b><\/h2>\n

An <\/span>optical CMM<\/b> is a newer, faster type of measurement system that uses high-end cameras and light sensors instead of a physical needle to “touch” the part. It provides non-contact measurement technology, which is a lifesaver when you are dealing with parts that might bend or break under pressure.<\/span><\/p>\n
