Description:

The article is focused on the choice of interpolation types for toolpaths in NC programs. Interpolation type affects the interpretation of an NC program by the control system used in a CNC machine tool. It is important for a production engineer to know about the consequences of the use of various interpolation types in a specific CAM system for toolpath creation. For testing purposes, a general profile of a blade typically utilized in energy devices was used, with toolpaths for contour milling of its profile based on three interpolation types available in the CATIA CAM system (linear int., linear + circular int. and spline interpolation). The comparison of toolpaths is based on the number of blocks of the NC program, feed-rate profile measurement and measurement of machining time. For the machining and measurements, a real three-axis machine tool with the Sinumerik 840D control system has been used. and Obsahuje seznam literatury
