Abstract

Path Interval and Its Relevance to Cutting Force in Ball and Filleted End Milling

Highlights

Computer numerical control (CNC) machine tool with digital twin technology is starting to become increasingly common all over the world
When a scallop height was set to double value in the same kind of tool, the path intervals were given as about 1.4 times the values in ball end milling
The values of increasing rate with increasing h in ball end milling were larger than the ones in filleted end milling, whereas material removal rate (MRR)(2) in filleted end mill was more than double the value, compared with the one in the corresponding radius of ball end mill

Summary

Introduction

Computer numerical control (CNC) machine tool with digital twin technology is starting to become increasingly common all over the world. Tool management using digital twin technology is attracting attention to improve manufacturing efficiency and machined surface feature [3, 4]. Process planning is commonly implemented through computer-aided manufacturing to create manufacturing process information essential for operating a machine tool [5, 6]. CNC milling process is being widely used as one of the core manufacturing technologies [7]. Tool path generation can provide manufacturing process information for a milling process, whereas there are a variety of the machining parameters affecting surface quality, machining accuracy, manufacturing efficiency, and so on [8,9,10,11]
