Abstract

The invention relates to an on-machine measuring error collecting device and method. The device comprises a linear error measuring module, an angle error measuring module, a data receiver, a laptop, an ARM main control board module and a related connecting wire. The linear error measuring module and the angle error measuring module are connected with the data receiver through a radio transmission system. The laptop is connected with the data receiver through an RS232 interface and is connected with a main control board through a USB port. During practical operation, an established data storing format and a relative program are guided into the ARM main control board module, the on-machine measuring error data receiver and the ARM main control board are directly connected, and on-machine measuring errors are collected in real time.

Description

technical field [0001] The invention relates to an on-machine measurement error acquisition device and a method thereof. Background technique [0002] For the error theory of off-line coordinate measuring machine, researchers at home and abroad have conducted long-term and unremitting research on it, making the data processing method and accuracy evaluation theory for off-line coordinate measuring machine measurement error more and more perfect. However, the research on the measurement error of the on-machine measurement system is not the case. Due to the late and incomplete formation of its knowledge system, many problems are still in the exploration stage. Therefore, this project aims to improve the measurement accuracy of the on-machine measurement system based on CNC machine tools. measurement capability. Contents of the invention [0003] The invention provides an on-machine measurement error acquisition device. [0004] The invention also provides an on-machine me...
