Five-axis CNC milling machine tools bring great facility to produce complex workpieces with increased dimensional accuracy and better surface quality in shorter machining times. However, kinematics of five-axis machine tools has a complex form which makes it difficult to operate these machine tools properly. The difficulty arises from the complexity of NC-Code generation and tool path verification. Collision of machine tool or setup components with each other is a severe problem in five-axis machining operations and usually results from inadequate postprocessors or insufficient collision checking due to absence of well-prepared simulation and verification programs. Five-axis CNC machine tool owners may get rid of this problem by purchasing commercial postprocessors, simulation and verification programs. However, these programs are expensive and small and medium enterprises (SME&rsquo / s) usually cannot afford the costs of these programs. In the related libraries of commercial programs, there is great number of CNC machine tools, which is generally unnecessary for SME&rsquo / s. An alternative to overcome this problem is to develop particular program, which is capable of postprocessing, simulating and verifying milling operations, for each certain five-axis CNC machine tool.
In this study, a software named &ldquo / Manus 1.0&rdquo / , which performs postprocessing and simulation processes, has been developed for the high speed &ldquo / Mazak Variaxis 630-5X&rdquo / CNC five-axis machine tool, located in METU-BILTIR Center. Moreover, tool path verification algorithms have been developed to detect collisions. The software has been written in Borland C++ Builder5.0. The developed program has been tested in sample milling operations and satisfactory results have been achieved.
