Non-contacted optical measurement system with 16-channel synchronous laser sensor applied for three-axis machine tool

The quality and accuracy are the two main factors of the performance of the cutting tool which are the particularly industrial standard in every almost factories. In this paper, an optical based non-contact machine tool calibration system is presented. It presents a non-contacted optical measurement system with two 8-channels sensor applied for three-axis machine tool with high-speed data accuracy, establishes system connection, and integrates computer interface with a 32-bit MCU to realize optical measurement system of three-axis machine tool. The communication is based on Ethernet network. Hardware architecture contains four sets of laser light source, photoelectric sensors and spherical lens. With the inexpensive price and uncomplicated steps, it can perform the calibration three-axis motor and static error with above average accuracy.
