Energy-efficient vector field based toolpaths for CNC pocketmachining

We found that: 1. Toolpath strategy: No single toolpath strategy (topology) may be universally adapted as “the most energy-efficient” strategy to follow when generating toolpaths for 2.5–5-axis CNC milling. For instance, a true-spiral strategy in MasterCAM was generally found to be more time and energy efficient for non-rectangularWe propose a novel method to generate 2.5D CNC milling toolpaths that have characteristics designed for reducing energy usage.

A Simple Method to Tool Path Generation for Cone Surface on CNC

Abstract. In this paper, we present a method for generating tool paths for cone surfaces with line generatrix in 3 axes CNC milling machine. The tool paths are planned in order to minimize the total machining time. The fundamental principle of the presented method is to generate the tool paths according to a preferred constant scallop Trochoidal milling is a promising strategy for machining pockets with difficult-to-cut materials.

HSM toolpath generation with capsule-based region

This work focuses on smooth toolpath generation for HSM pocketing. The concept of region subdivision is proposed and implemented. With this concept, the input pocket is firstly subdivided into two classes of sub regions: the HSM regions and the low-speed machining (LSM) regions. For the HSM regions, very smooth path curves are filled This is typically done by selecting various CAM Operations or Toolpaths. An Operation or Toolpath is typically aimed at machining a particular Feature on the part, and we often refer to the Toolpath and the Feature by the same name, such as a “Hole” or a “Pocket”. But not always–“2D Profiling” cuts “Vertical Walls” around theComplete Guide to CAM Toolpaths and Operations for Milling
