Development of Lathe Static Rigidity Computer Testing System

The structure characters of lathe and the force of turning craftwork system was analyzed. Based on the advantage of static rigidity device of traditional lathe the static rigidity testing system using computer controlled was developed. The system consists of computer as for signal measurement, data processing and controller core, precision displacement transducers, pressure transducers, step motors and drivers etc. It automatically loads and unloads, samples, data processes, directly plots, displays and prints the rigidity curve etc. The success of the system provides an advanced means for testing lathe static rigidity. The testing results show that the system has the advantage of high automatization, high testing efficiency, high accuracy, high reliability and steady testing capability.
