Institutions of Cutting-aided Design System Development Program DAPCR

The paper introduced the method of design of DAPCR by Visual Basic.And show how to design of the simple mechanical model which is suitable for calculation and deduce the mechanical formula for the program.Compare the language and data-base for DAPCR application development and how to call the third-party software are discussed.The cutting force distribution map of the roadway cross section can be drawn by DAPCR,which can evaluate the roadheader Mechanical performance.
