Freeform surfaces, also called sculptured surfaces, have been widely used in various
engineering applications. Freeform surfaces are primarily manufactured by CNC machining …

The application of the STEP-NC standard boosts the CNC machining industry towards
integration plus automation. Cutting tool selection, considered as a primary task in the …

An offset algorithm is important to the contour-parallel tool path generation process. Usually,
it is necessary to offset with islands. In this paper a new offset algorithm for a 2D point …

Barrel cutters have been widely used in the flank milling of blisk. In this paper, a new method
is proposed to select an optimal barrel cutter in the interest of the high productivity in the …

Tool sequence selection is an important activity in process-planning for milling and has
great bearing on the cost of machining. Currently, it is accomplished manually without …

While 5-axis CNC machines improve the manufacturing productivity, the tool-path
programming demands human expertise and tremendous time investment to generate …

This paper presents a new process planning method for five-axis machining, which is
particularly suitable for parts with complex features or weak structures. First, we represent …

The selection of cutting tools in die/mould-cavity NC machining affects not only the
machining time and costs, but also the process quality. A systematic methodology for cutting …

This work has created a completely new geometry representation for the CAD/CAM area that
was initially designed for highly parallel scalable environment. A methodology was also …

This paper describes algorithms for efficiently machining an entire setup. Previously, the
author developed a graph based algorithm to find the optimal tool sequence for machining a …
