How to Control The CMM Accuracy In Real Time

Jan 19, 2017

Many users are not clear their own coordinate measuring machine(CMM) precision after using a period of time. How to control the CMM accuracy in real time, Here recommend some method of introspection.

1. Using standard inspection tool

The best way to check machine precision is with standard inspection tool. Gage block, ring gauge, sphere, high precision angle square, etc. When the temperature changes or higher measurement precision needed, we can use above standard tool to examine the length, roundness, diameter and other parameters. When it is necessary, we can also carry on the appropriate correction. It is very useful for the operator.

2. Using standard work-piece

Using standard work-piece to inspect machine accuracy, but is relatively more complicated, it can only carry out in a period of time. More convenient way is to use a typical work-piece, complete automatic measurement program, measure for many times under the well machine calibration. Then calculate according to the statistical regularity and record the reasonable value and tolerance range. 

If feel no confidence of the above two methods, you can also contact us and we will offer a variety of value-added services.
