“…Specifically, the main steps are (in their usual order): Helical-flute, Relief angle and Gashing. The mathematical models for the helical flute and the gash out machining are based on the enveloping theory and the fundamental analytical conditions of engagement between the wheel surface and the helical groove surface [6]. As shown in Fig.…”

To facilitate the manufacturing of a ball-end mill, this paper presents an algorithm for ball-end mills gashing by using a five-axis computer numerical control (CNC) grinding machine. In this study, the normal helix models are proposed. Then, based on the cutting edge geometric model and the machining mode of the five-axis computer numerical control (CNC) grinding machine, the coordinate of the grinding point when the step of the gash out is grinded will be calculated. With the input data of ball-end mill geometry, wheels geometry, wheel setting and machine setting, the NC code for machining will be generated. Then the code will be used to simulate the ball-end mill machining in 3 Dimension. The 3D simulation system of the ball-end mill grinding is generated by VBA and AutoCAD2008. The algorithm of ballend mill gashing can be verified by the 3D simulation system. Result shows that the algorithm presented in this paper provides a practical and efficient method for the manufacture of a ball-end mill gashing.

“…But the “S” shape of planar edge curve is not good, and the calculation is very complexity. So, Pham and Ko 8 built the mathematical model of the rake face, rear face and cutting edge of the ball-end milling cutter with orthogonal S-shaped edge curve, based on the analysis of the grinding method, and solved the problem about the smooth connection between the ball-end edge curve and the cylindrical helix edge.…”

Ball-end milling cutter with tooth offset center is widely used in machining industry, because it has higher machining efficiency and better stability compared with the ball-end milling cutter without tooth offset center. In addition, the tooth offset center has lower wear rate of the tool tip so the life of the milling cutter is improved. However, up to present, there is no mature and effective theory for the design and manufacture of this kind of milling cutters. This article presents a new mathematical model for S-shaped edge curve of the ball end taking the tooth offset center into account, which can construct accurate S-shaped edge curve for the ball-end cutting tools with tooth offset center as well as without tooth offset center. This model overcomes the complex computation and bad adaptability of the traditional modeling method. At the same time, a five-axis grinding algorithm for rake face of the ball end is also presented in this article. Finally, based on the application programming interface of CATIA™, a three-dimensional computer-aided design and computer-aided manufacturing system is developed. The accuracy and effectiveness of the grinding algorithm are verified by simulation in VERICUT™ and machining experiment in tool grinding machine.
