Partition-based 3 + 2-axis tool path generation for freeform surface machining using a non-spherical tool

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...

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...

Tool Path Generation for 5-Axis Control Machining Considering the Quality of Machined Surface

Tool selection and path planning in 3 - axis rough machining

We present a novel approach to CAD/CAM integration for 3-axis machining. Instead of redefining the workpiece in terms of machining features, we generate tool paths directly by using the accessibility of the surface of the part as the central and the over-arching constraint. This eliminates the problem of feature extraction. We envision this as the core strategy of a new direct and seamless CAD/...

Non-Isoparametric Three Axis NC tool path generation for finish machining of sculptured surfaces

Sculptured surfaces are usually machined to their final shapes by a series of rough and finish passes. After each pass, excess material may be left at some concave or C1 discontinuous areas. Traditionally these undercut areas are “cleaned up” by repeatedly machining the whole surface with progressively smaller cutting tools. We present an algorithm for automatically identifying areas with exces...
