The Effect of the Cutting Speed on the Surface Roughness When Ball-End Milling

Abstract

Using freeform surfaces in advanced industries is becoming ubiquitous and widely applied in many fields such as the aerospace, automobile, consumer products as well as the die and mold industries. The ball-end mill is mainly used in machining such surfaces. However, the manufacture of this type of surface is still somewhat difficult when machining using a 3D ball-end milling machine. Due to changes in the surface inclination, the working diameter of the tool also changes. Variations in the working diameter leads to an unstable cutting speed, affecting the roughness homogeneity of the smoothed surface. This article discusses the effect of changing the cutting speed on the surface roughness in the case of concave and convex surfaces.

Investigation of cutting force components and surface roughness in face milling with different cutting ratios

“…Easy machining process, low-cost production system, time and power saving, continuously increase product quality to answer customer demand, and environmentally friendly production system are the main points the manufacturing industry needs to address to compute in the market [2][3][4]. CNC milling machines are popularly used for metal cutting operations, especially in complicated and very detailed cutting processes [5]. Machines equipped with CNC control are even capable of a certain degree of autonomous operation [6].…”
