Simulation of the Basic Parameter Settings The analysis and comparison realized by experimental machining and measurement can prove that the high precision and quality can be obtained in the injection mold milling.Ģ.1. Research achievements will be used in the milling of the inner fillet of master mold or the outer arc of the mold heart. This paper focuses on the finish milling of the mold surfaces, the comprehensive analysis and comparison of the surface milling by using different processing paths that are performed to achieve the high precision and the machining quality. But these studies have not performed more comprehensive analysis about the tool path’s effect on the mold processing. Also, the technological parameters are studied for finding the most reasonable process parameter setting, so that the processing speed of the part can be improved markedly, and one aspect of the process setting is the tool path. MasterCAM is an widely used CAD/CAM software which can benefit the design and process the mould and die, but many studies are always focusing on using the MasterCAM to realize the automatic programming. Lots of papers are focusing on the milling processing of the injection mold, for example, many researches are devoted to studying the relations between the processing quality and the machining speed and feed rate, and also many studies are devoted to analyzing the difference of the dry milling and wet milling, which can markedly affect the processing quality, and many researches are focusing on studying that the different processing path can shorten the processing time and markedly increase the processing efficiency. The processing of the injection mold needs milling, grinding, EDM, and light etching process, etc., but the CNC milling process is still the fastest and the most economical way of achieving the main structure and shape of the molds. The results show that the milling effect of the arc isīetter and the waste is minimal in the parallel milling along the Z-X or Z-Y Then the experimentalĬutting processes are performed correspondingly and the surface roughness and theĪccuracy are measured.

Simulations of the milling process that are performed. At the same time, end miller, arc miller andīall miller are respectively selected in the software. Parallel milling along the Z-X or Z-Y axis direction and the streamline WeĬhoose three paths: the parallel milling along the X-Y axis direction, the in these simulations, but different processing paths are used.

The same processing conditions with same parameters such as speed, material andįeed rate etc. In order to analyze how the tool path affects the roughness of the surfaceĪfter milling, series of simulations are implemented in MasterCAM. Roughness is one of the most important evaluation indexes in machine cutting.
