Effective Tool Pass Generation Method for Roughing in Multi-axis Control Machining

Automatic Tool Path Generation for Multi-axis Machining Automatic Tool Path Generation for Multi-axis Machining Chapter 4: Tool Path Generation Strategy

We present a novel approach to CAD/CAM integration for multi-axis machining. Instead of redefining the workpiece in terms of machining features, we generate tool paths directly by analyzing the accessibility of the surface of the part. This eliminates the problem of feature extraction. We envision this as the core strategy of a new direct and seamless CAD/ CAM system. We perform the accessibili...

A generic uniform scallop tool path generation method for five-axis machining of freeform surface

In this paper, a generic uniform scallop tool path generation method for five-axis machining is presented. Unlike the conventionalmethodswhich are based on the local surface geometry assumptions, thismethod is inspired by cutting simulation. Initially, the designed surface is planted with dense grasses. If a cutter is put onto the surface, the affected grasses will be cut short. All the affecte...

Tractrix-based tool orientation control for 5-axis CNC machining

We consider a 5-axis CNC machine whose tool axis maintains a fixed angle with respect to the surface normal as the machine tool cuts a given path on a smooth surface. The tool axis a(ξ) lies on a cone of constant angle ψ about the surface normal n(ξ) at each point of the path, but its azimuthal position on this cone remains indeterminate. Geometrically speaking, given a curve n(ξ) on the unit s...
