Abstract: (298 Views)

The milling process is widely used in the manufacturing industry to shape complex geometric parts. Considering the flexibility of the cutting process and the various variables involved, process optimization has become a key issue in achieving higher productivity and quality. To optimize the process planning, it is important to choose a suitable machining strategy. Implementation and selection of tool path strategies and orientations are very important in the machining process, especially in the aerospace and molding industries. The right choice can lead to significant savings in machining time, improvement of work-piece surface quality, and improvement in tool life, thus leading to overall cost reduction and higher productivity. Therefore, this article aims to identify the best strategy in terms of surface roughness and milling time. In this article, Shallow's strategy has been investigated, and the milling of its finishing stage has been studied and compared with three strategies of the milling process, including raster, 3D offset, and raster flat. In this article, the comparison of the strategies in the Powermill software and with the flat-head finger mill, which can grind the floor and the wall simultaneously, has been done. Tool-cutting parameters were considered constant for all tested strategies. Machining quality was evaluated by comparing surface roughness, surface Topography, and dimension control parameters. The results indicate that the Shallow machining strategy has the lowest surface roughness and the best surface quality, and the raster strategy has the highest surface roughness and the worst surface quality in this test.

Keywords: Milling Strategies, Shallow, Surface Topography, Surface Roughness, Milling Time, Powermill Software
