Abstract
Machining with rotary tools using all insert circumstances instead of a specific cutting edge reduces tool wear and thus increases its life. This method, in addition to the simplicity of the mechanism, is considered one of the cheapest environmentally friendly processes. The important role of the inclination angle on the outputs has been pointed out. For this purpose, according to the forces and geometrical conditions, a suitable tool holder is designed and built in which it is possible to change the inclination angle. Aluminum 7075 has been selected as the workpiece, and the turning operation has been done using appropriate tools. The surface roughness of the workpiece is measured based on input parameters such as feed and inclination angle. The design of the experiment is based on full factorial design, and surface roughness has been measured based on the angle of inclination in three modes and three different feeds. Reducing the inclination angle and the feed has improved the quality of the surface. The best surface roughness has been at an inclination angle of 5 degrees and an advance of 0.12 mm/round. The shape of the chips has also been investigated. Ribbon-type chips were formed at higher inclination angles, but conical helical chips were formed as the inclination angle decreased.
