Abstract
The paper aims to analyse the processing of convex complex surfaces with toroidal milling cutters compared to spherical milling cutters. As comparison terms, surface roughness and processing time are taken into account. The main purpose of the paper is to demonstrate the usefulness of the toroidal milling tool that can be replaced in case of spherical milling cuts to improve the working time as well as the surface quality, these terms playing an important role in the processing of convex complex surfaces.
Highlights
Complex and convex surfaces are encountered in many situations, such as aerospace, automotive, matrix, and pneumatic actuators
Surfaces are 3D generated using a CAD program, helping to describe geometry in order to generate the trajectory of the milling tool. [1]
In the paper (Hayajneh et al, 2007) [2] are presented the effects of the parameters of the cutting process on the surface roughness. Factors such as the speed, feed, and depth of cutting that define the cutting process can be set in the initial phase, while factors such as tool geometry, tool wear, splintering, or tool material properties are uncontrollable (Huynh & Fan, 1992 )[3]
Summary
Complex and convex surfaces are encountered in many situations, such as aerospace, automotive, matrix, and pneumatic actuators. In the paper (Hayajneh et al, 2007) [2] are presented the effects of the parameters of the cutting process on the surface roughness. Factors such as the speed, feed, and depth of cutting that define the cutting process can be set in the initial phase, while factors such as tool geometry, tool wear, splintering, or tool material properties are uncontrollable (Huynh & Fan, 1992 )[3]. [8] argues that productivity machining operations spherical milling head is significantly effective when it is performed on CNC machine tools, which allow a high flexibility cutting conditions. In matrix processing, where spherical milling machines were typically used, toroidal cutters eliminate much more material and faster, improving productivity. Optimization of machining operations is fundamental when it is desired to reduce the cost of production of matrix or complex surfaces
