The Error Estimation for 5-Axis Spindle-Rotating CNC Machine Tool

Abstract:

5-axis CNC machine is be the best tools in sculptured surfaces machining. Current CAM algorithms for 5-axis machining only consider the surfaces' geometric information when generating cutter contact points (CC points). Hence, the step length, which is the distance between two CC points, is determined only by the surface parameters for current CAM system. Because of the cutting tool can rotate, the actual cut trajectory is no longer a straight line between two consecutive CC points for 5-axis machining. Thus the cut error and the maximum step length should depend on the structural of 5-axis CNC machines tool and the surface's geometry. This paper proposed a new algorithm to estimate the maximum step length based on the cut error of 5-axis machining, and the result shows that this estimation algorithm provides better than traditional algorithms.
