“…Every point in the C-space corresponds to a set of independent parameters that characterize the position and orientation of the rigid object. Choi et al applied the Cspace approach to 3-axis NC tool path generation for sculptured surface machining [5]. Tool paths generated from the C-spaces were gouge-free and collision-free.…”

Effective cleaning with high pressure waterjets requires direct impact of jets and sufficiently high impact pressure. The objective of this research is to find all such cleanable regions, given a CAD model of a workpiece, by means of geometric accessibility analysis. We use a configuration space (C-space) approach for addressing the problems of both optimum surface proximity for effective cleaning and collision avoidance between the cleaning lance and the workpiece. Minkowski sums are used to compute the C-spaces and cleanable regions are then found by visibility analysis. Implementations and results for 2D examples are shown to validate the approach.

“…These conventional approaches are suitable for gougefree tool path generation, but the rest of the requirements can hardly be achieved by these approaches [20]. In this paper we present a new approach to SSM, called C-space approach, in which the geometric data describing the design-surface and stock-surface as well as tool shape are transformed into C-space elements, and then, all the tool-path generation decisions are made in the configuration space (C-space).…”

Abstract:Presented in the paper is a new approach to tool-path generation for sculptured surface machining. In the proposed C-space approach, the geometric data describing the design-surface, stock-surface and tool shape are transformed into C-space elements, and then, all the tool-path generation decisions are made in the configuration space (C-space). The C-space approach provides a number of distinctive features suitable for sculptured surface machining, including: I) gouge-free tool-paths; 2) uncut handling; 3) balanced cuttingload; 4) smooth cutter movement; 5) collision-free tool-path.

“…This quality is essential for multiple 3-axis setups or 5-axis simulation capabilities. Choi et al [12] used a Z-map for tool path planning and verification of 3-axis machining. Fussell et al [13] employed a Z-map for feed-scheduling of 3-axis tool paths.…”
