Computer Analysis System of Mechanical Working Precision

In this paper,computer analysis system of mechanical working precision is presented.This system is made up of a displacement sensor,amplified circuit,A/D shifter and a computer.In this system,the workpiece's size is collected automatically by the displacement sensor and the A/D shifter,and delivered to the computer where the data are dealt with.The information such as the distributed curve of the machining error,the X-R chart,qulity rate,error rate etc,are obtained.So the error analysis is more rapid and more accurate.The system makes the analysis on line possible,and the aims of adjusting the technology system in time,reducing waste product,raising productive efficiency can be reached.
