in this paper we present a new method for tool-path generation and adaptive interpolation for a three-axis cnc milling machine. this method satisfied the force and / or the error conditions by using a variable-direction variable-feedrate strategy based on maximum feedrate map. the proposed adaptive interpolator modifies the cutting path and the moving direction according to the actual instantan...

Signi cant advances have been made in the area of macro planning for assembly operations (i.e., dividing a product into sub-assemblies, determining the sequence of assembly operations). On the contrary, the state of the art in micro planning (i.e., tool selection, path planning for tool and part movements) is rather primitive. To generate a realizable assembly plan, both macro planning and micr...

Contour-parallel offset (CPO) machining uses successive offsets of the boundary curves of the machining region as the tool-path-elements (TPEs). For the efficiency of the CPO machining, it is very important to minimize the number of tool-retractions, which cause additional tool movements and do not contribute to the actual cutting. Presented in the paper is a CPO tool-path linking algorithm, wh...

Purpose – This paper aims to develop path-planning techniques that support a general selective disassembly planner in a virtual reality environment. Design/methodology/approach – The paper presents an automatic selective disassembly planning and two path-planning techniques that support it. The first one is based on single translations, while the second is based on the generation of a random se...

Currently, an automated surface treatment or finishing (e.g., abrasive blasting, cleaning or painting) is performed in two consecutive steps: first processing by tool, second quality evaluation by sensor. Often, a finished surface has defects like areas not properly processed. This is caused by path inaccuracy or errors in tool deployment. The defected areas can be detected only during a subseq...
