New Approaches in Tool Path Optimization of CNC Machining: A Review

Abstract

Computer numerical control (CNC) machines have been widely used in automotive manufacturing industries especially of machining operation in automotive part such as engine body and cylinder. One of the key features that improve efficiency of CNC machining is through the optimization of tool path. Previous researcher to optimize tool path has premeditated several approaches. This paper aims to provide a critical review of those approaches that have been developed in tool path. The developed tool path approaches covered different types of machining process under various constraints condition. This paper focuses on tool path generation in CNC machining such as milling and cutting process. Based on our finding, this review paper collects information on tool path optimization and recommends future research direction.

Path Optimization of Multi-tool Drilling Using Genetic Algorithm

“…Much of the existing literature on hole drilling focuses on drilling holes of the same diameter. Narooei et al (2014) propose an approach using Ant Colony Optimization (ACO) to reduce tool path and study the effects of changing parameters on the optimal solution. However, this approach is only tested on small drilling operations with a limited number of holes.…”

A Non-Uniform Offset Algorithm for Milling Toolpath Generation Based on Boolean Operations

“…Process productivity has been increased during the last decades by exploiting the advancements in tooling system, machine structure and numerical control (NC). The latter, in synergy with modern CAD/CAM software, allows for the implementation of advanced toolpath strategies [1]. Traditionally, in 2.5-axis milling, two main strategies are used: direction-parallel and contour-parallel [2].…”
