Development of CNC software for single point diamond precision lathe based on UMAC

Abstract

A precise single point diamond turning (SPDT) CNC software is developed on the Windows platform using QT4.8.1 graphical interface development tools, with the calling of the UMAC library function. This paper introduces the hardware design of precise SPDT CNC system, the communication method between QT and UMAC, the design and implement of the main interface of the software, the implement of the basic motion control, the process of each module and the software three-dimensional (3D) simulation of this system. The result of the 3D simulation shows that the design of the system is reasonable and the system is able to achieve good processing results. Such a numerical control system has a certain economic value and prospects for industrial applications.
