This paper presents a regionbased 3 + 2axis machining toolpath generation method with 5axis machine tool. The surface is first divided into several preliminary subsurfaces using Kmeans clustering algorithm. A post processing procedure is then carried out to optimise the preliminary subsurfaces to ensure the machinability.

Abstract. Multiaxis CNC machines are widely used to manufacture complex industrial parts such as dies and molds. The current CNC toolpath planning strategies are complex and often lead to inefficient part programs. This paper presents an approach to use voxelbased CAD models for efficient zigzag toolpath planning.

When the CNC machining of continuous small line segments is performed, the direction of the machine tool movement will change abruptly at the corner of adjacent line segments. Therefore, a reasonable constraint on the feedrate at the corner is the prerequisite for achieving highspeed and highprecision machining.

CNC milling toolpaths are typically categorized as 2D, 3D, 4axis, and 5axis. However, the term 2D is a bit misleading since this toolpath uses the Zaxis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.

Curve 5axis: This toolpath is one of Mastercam's oldest and most popular. The cut pattern follows a curve (a line, a spline, a circle, or a surface edge) that can be wireframe, solid, or surface. Swarf 5axis: Sometimes called "Flankmilling," Swarf 5axis uses the side of a tool to cut a wall. It is very popular in aerospace milling.

A CNC machine's toolhead can move in multiple directions depending on the type of machine being used. Starting from twodimensional cutouts, the complexity goes all the way up to 9axis machining. In CNC terminology, the spindle or router holds the toolhead that chips away at the workpiece. Like with a 3D printer, it can usually move in three ...

An important 2D/3D difference for CAM programs is that 3D machining is frequently divided into a very distinct roughing and finishing stage. The bulk of the stock material is removed by the roughing toolpath as quickly as possible, although it may leave a poor quality surface. Finishing toolpaths are used to remove a small amount of material ...

A roughing toolpath is generally used in the CAD/CAM cnc programming phase for removing the most amount of material possible, as accurately and as efficiently as possible. Finishing toolpath comes after roughing and essentially "finishes" the cutting process removing the last amount of material on the machine to complete the machining process.
