“…Two methods are used to compute the CL points on the test surface for comparison. Method 1 is Xi’s method 12 and Method 2 is the method presented in this paper. Since Xi’s method is designed for perfect torus cutters, the cutter will be estimated to a perfect torus by making the semi-minor axis b equal to the semi-major axis a .…”

In mould manufacture the elliptical torus cutters are used for their high cutting velocity, but the special geometry also brings issues in tool path generating and machining quality controlling. In this paper a guide curve tool path generating method for elliptical torus cutters is presented with the cutter location points computed by a minimum distance algorithm and the path spacing determined by an adaptive method. In the minimum distance algorithm, the calculation is resolved into an iterative process from point to freeform surface and an algebraic calculation process from point to elliptical torus surface considering the geometry of the cutter, which reduces the iterative process and improves the computing speed. In the adaptive path spacing method, the contacting geometry between the elliptical cutter and the workpiece surface is analysed and the relations among the scallop height, the tool tilt angle and the path spacing are deduced, based on which the guide curves are adjusted in advance to control the scallop height. Calculating examples and experiments are carried out, showing that the consuming time of cutter location (CL) points computation algorithm is reduced by 30% comparing to earlier method, and the adaptive path spacing method performs better than constant method in both scallop height controlling and tool path shortening. The results indicate that the presented tool path generating method can help to reduce both the machining and machine waiting time as well as ensuring the machining quality.

“…Three different impeller families were presented, the differences of their machining are studied, flank milling and point milling strategies are compared, and the blade finishing strategy was optimized. Fan et al 6,7 presented a rotary contact method for five-axis sculptured surfaces machining. The rotary contact method found the optimal tool positions by rotating the tool backward could generate big machined strip width, and the improved rotary contact method is developed to improve and perfect the rotary contact method.…”

This article presents an efficient tool path generation method for five-axis machining of a difficult machined centrifugal impeller. Geometry of centrifugal impeller is analyzed, and the inherent low efficiency of the machining of difficult machined centrifugal impeller is obtained. The tool path curves which are calculated by the most common isoparametric method are shown to testify the waste in machining. The new type machining layers are calculated, and the new machining regions are achieved. The new tool path curves in each new machining region are calculated, and they are sparser and triangular. For the inherent low machining efficiency of difficult machined centrifugal impeller, the machining time can be greatly reduced just by the optimizing tool path generation method in this article. Numerical simulation and a real test impeller are presented as the test of the proposed method.
