- Free-form surfaces are widely used in CAD systems to describe the surfaces of parts, such as molds and dies. The surfaces are often produced by three-axis CNC machines using ball-end cutters.To automate the design/manufacturing process, algorithms for efficient path planning based on accurate tool-path intervals are needed. Method
- This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining.
