Based on their measurement methods, CMMs can be categorized into 'non-contact types' and 'contact types'. In this section, we introduce manual-method and CNC (Computer Numerical Control)-method CMMs offered by various manufacturers. If you're considering implementing a CMM, this will be an essential guide for you.
Manual-method CMMs are operated by hand, using controllers or other devices. The advantage of manual CMMs is the ability to manually explore and measure values. They are recommended for measuring prototypes with unique designs, products affected by warping or shrinkage, such as plastic items, and samples with ultra-complex shapes or tiny gaps.
However, manual-method CMMs also have some drawbacks. Measurement results can vary based on the operator's skill and perception, and repeated measurements can be time-consuming.
Here, we introduce the "CRYSTA-Plus" by Mitutoyo and "ALPHA" by Hexagon Metrology, including their features and specifications. If you're considering implementing a manual-method CMM, please check this page for more details.
CNC CMMs are capable of automatic measurements. The tool head and other operations are automated and precisely controlled by a computer.
The advantage of CNC CMMs is their ability to perform high-precision measurements quickly and easily. The operator simply places the object in the specified position and runs the measurement program. CNC CMMs are consistent in their performance regardless of the operator, and can handle complex workpiece shapes and precise measurement tasks efficiently.
However, using CNC CMMs requires creating and testing dedicated programs, which can be time-consuming and labor-intensive. Therefore, they may not be suitable for prototypes with unique designs or measuring wide a variety of products.
Here, we introduce the "CRYSTA-Apex" (Mitutoyo), "ZEISS DuraMax" (Carl Zeiss), and "GLOBAL Touch+" (Hexagon Metrology), along with their features and specifications. If you're considering implementing a CNC CMM, this will be a valuable resource.
