“…In recent years, domestic and foreign scholars have done a lot of work for this, however, most of them only focused on the processing tool and surface on the local interference and its correction [1,2,3], that deal with the problem of the tool head cut off the surface, there is little literature dealing with the global intervention [4,5]. However, surface machining not only need to deal with local interference, but also check the arbor and adjacent surfaces to interfere with the collision problem, the global interference problems.The tool can not collide with the adjacent surfaces when the tool in the processing of a surface.…”

Proposed a construction method of visual cone, to solve the surface 5-axis NC machining tool interference problems with the surface. At any point on the surface structure the visual cone area, according to visual cone determine whether the global tool interference with surface, and correct the tool spindle of interference cutter, solved the global surface and tool interference problems successfully. The application shows, this method is of high efficiency, high precision.

“…In the NC turning process, especially in finish machining, the compensation of NC lathe tool tip's radius is desperately necessary. That the compensation carried out by the location of the cutting point may considerably lead to enhancement of the accuracy of the machined workpiece and reduction of the machining cost have great theoretical value and practical significance [3].…”

With the wide use of NC, higher accuracy in machining is increasingly required for premium mechanical components. However, machining accuracy is affected by many factors, especially by the way of the tool positioning and the geometry of the tool nose. This paper, based on the actual NC lathe tool and turning, generalized and abstracted the machining process by establishing the imaginary tool nose and the tool tip’s arc centre as the cutter-contact point, and analyzed systematically the influence of the factors, including the way of the tool positioning, the nose, and the tool tip’s arc radius, on the machining accuracy when machining transverse, cylindrical-surface, circular cone, quarter-circular and some surfaces can be expressed by formula etc.. Derived the error calculating formulas for turning in different surfaces. Put forward two error compensation methods, direct calculating method and enveloping method of error compensation. Experiments were carried out and results have shown that the two error compensation methods can considerably reduce the machining error in NC turning operations.

“…Hwang [7] presented a two-step method to generate a gouge-free tool path; ®rstly, the points obtained from a compound surface are converted into a triangular polyhedron; subsequently, the tool path is generated from the polyhedron, and an e cient algorithm is used in the calculation of CL data. Yu and Deng [8] introduced a method to generate a gouge-free tool path for non-spherical cutters; a tangent plane is constructed at a point on the surface as the initial orientation of the cutter and then the ®nal orientation of the cutter is determined without interference.…”

This paper presents a new method for the detection and elimination of global interference in five-axis machining of sculptured surfaces. Projecting points on the surface to the axis of cutter, the minimum distance from surface to cutter axis can be directly calculated by an iterative algorithm; the amount of interference is subsequently determined. A corrective method for generating an interferential-free cutter location is then proposed. The implementation has proved that the proposed method has a high efficiency and precision.
