Computer aided part program generation and simulation of turning processes

ABSTRACT COMPUTER AIDED PART PROGRAM GENERATION AND SIMULATION OF TURNING PROCESSES DERELİ, Türkay M. S. in Mechanical Engineering Supervisor: Prof. Dr. İ. Hüseyin FİLİZ June 1994, 128 pages In this study, a computer program is developed for both the automatic generation of CNC part programs and tool paths, and their computer simulation, for lathe operations. On tiie basis of the controller unit of a specific machine tool (i.e., Boxford 250B CNC lathe), the part program to proceed to actual production is automatically generated in standard G and M codes by processing a CAD/CAM data base. The generation can be performed by using either absolute or incremental co-ordinate system. Both the chip removal processes and tool paths (the plot of cutter locations) can be simulated for the verification and realisation of the codes proposed by tiie program. The generated part programs can also be printed, and stored for future use. The program is written in C++ programming language on an IBM compatible personal computer. The use of the program is illustrated through examples. Key Words: Computer Simulation Of Turning Operations, and CNC Part Program Generation. Ill
