Abstract
This invention discloses a method and system for measuring a CNC machine. The system comprises a platform, a driving module, a set of optical scales, and a detection module. The platform is driven by the driving module. In addition, the driving module further comprises a set of encoders. As the driving module drives the platform to move to a position by a first displacement, the encoders indicate the first displacement. The optical scales indicate a second displacement by which the platform is driven by the driving module. The detection module detects the difference between the first displacement and the second displacement.
Claims18
A Computer Numerical Control (CNC) machine tool measuring system, including:
- a platform;
- a driving module comprising a set of encoders, wherein the driving module drives the platform to move to a designated position by a first displacement indicated by the set of encoders;
- a set of optical scales for indicating a second displacement by which the platform is driven by the driving module;
- and
- a detection module for detecting a difference between the first displacement and the second displacement, wherein the difference corresponds to the designated position.
A method for measuring a CNC machine tool, including:
- driving a platform to move to a designated position by a first displacement by a driving module, wherein the driving module simultaneously makes a second displacement;
- obtaining the second displacement by a set of encoders in the driving module;
- obtaining the first displacement by a set of optical scales, wherein the set of optical scales measure the first displacement during platform movement;
- and
- comparing the first displacement and the second displacement to obtain a difference therebetween, wherein the difference corresponds to the designated position.
