Study on control scheme of on-line measurement system for key dimension of spinning head

Abstract

According to the basic principles of roller measurement and displacement measurement, the on-line measurement system of the outer circumference and roundness tolerance and its control scheme are discussed. To implement automatic and real time measurement of circumference and roundness tolerance, the S7-200 PLC is selected as the controller, the STEP7-Microwin V4.0 is used for programming, the ladder diagram is used as the programming language. The motion simulation test of the measurement system is carried out, and the results show that the control scheme is feasible.
