“…In recent years, the tool path planning method based on the discrete triangular meshes has been widely used by many researchers [4][5][6]. Cha-Soo Jun [4] et al presented the polyhedral model of the STL format that can be used to plan the gouge-free tool paths based on the curve-based approach.…”

The multi-patches structure are widely used in various types of complex structure products such as the snubber of blade in the engine manufacturing industry. These parts are often machined with five-axis machine tool. When using the normal tool path planning method, it will be difficult to offset the surfaces and there will be redundant cutter retraction. In order to solve the above problems, this paper presents a high efficiency planning method for five-axis spiral tool path generation based on the point model of the multipatch island. Firstly, discrete points are extracted from the initial model to construct the point model of the snubber and they are stored in different regions in order to decrease the range of searching cutter contact points. Secondly, on the basis of creating the control line for searching direction, the cutter center for every cutter location is calculated according to the generated clean-up tool path. Finally, the tool axis of each cutter location is obtained based on the tangent vector of the spiral tool center path. Example and simulation are carried out finally to show the feasible and effectiveness of the presented method.

“…The existing methods about removal of the residual areas can be divided into two categories: supplement tool path to the original path [3,4] or remove residual areas after original machining [5][6][7]. The former one can only solve the residual areas caused by the corner of tool path, but cannot deal with the residual areas caused by other factors such as the corner of workpiece.…”

“…Unfortunately, advances in theory for clean-up tool-path generation have not kept pace with the increasing usage of complex parts with freeform surface and the advances in NC(Numerical Control) technology. A number of commercial CAD/CAM systems including UG, CATIA, are capable of generating clean-up tool paths, but very few methods have been openly published [1][2][3][4]. Some researches have been aimed at solving this critical problem.…”

“…It utilizes a series of intermediate virtual cutters to search for clean-up boundaries and construct the clean-up tool paths. Kim [2] employed a curve-based approach for clean-up machining. The pencil-cut and fillet-cut paths for a polyhedral model of the STL form with a ball-end mill are obtained from the curve-based scanning tool paths on the xz, yz, and zy planes.…”

“…It works well when there are fewer surfaces, however, it is very complicated and time-consuming to construct the offset surface exactly and completely when the number of the surface is large [6][7]. In order to generate effective clean-up tool path, the polyhedral model is often employed in the research, including those by Ren [8] and Kim [2]. In Ren's research, a contraction tool method was proposed to detect gouging and generation clean-up tool paths for machining complex polyhedral models.…”

Focusing on the clean-up tool path generation for multi-patch solid model, a new efficient and robust searching approach is presented in this paper. The multi-patch solid model is considered as an integrated object other than dealing with surfaces on the solid model. The initial points are selected on the part surface in the physical domain, and then the points are converted into the parametric domain to determine the search center and the search direction. After that, the search operation is carried out in the parametric domain, while the cutter-center point is calculated in the physical domain. Finally, a cutter-center curve of the clean-up tool path is fitted with all the searched points. In this paper, some illustrative examples are provided and the results show that the method is feasible and efficient.
