Design of the CNC Precision Automatic Measurement Control System Based on Step Gauge

Aimed at the disadvantage of big workload,low efficiency and low accuracy in traditional manual CNC precision measurement with step gauge,a CNC precision automatic measurement control system using digital dial gauge is put forward,which can acquire the measurement data and transmit the CNC data. The system hardware principle diagram is discussed,and the effect of each component is analyzed. The PC software system is developed and its structure and implement method is elaborated. The parameter setting is given and system testing software interface is shown.
