Abstract

With respect to two or more NC data points among a group of dots together representing a tool locus, a curvature radius of the tool locus is determined. Then, the NC data point and its succession with other points is displayed in a display color determined according to the magnitude of the curvature radius. Alternatively, a movement direction of each minute segment relative to a specific axis selected from the three (XYZ) axes is determined as either positive, negative, or zero, and the minute segment or an end point thereof is display with the display property determined according to the movement direction. Still alternatively, after a specific axis is selected from the three (XYZ) axes, a region relative to the selected region is divided along the selected axis, for predetermined dividing width, first beginning with a predetermined reference point, and the resultant divided regions are given predetermined display properties. Then, a tool locus is displayed in the three-axial (XYZ) system according to the display properties given to the respective divided regions.

Description

technical field [0001] The present invention relates to a method for displaying a tool locus delineated by NC data, and in particular to an improved method for displaying a tool locus delineated by NC data for machining surfaces having any shape , the toolpath is lined up with points in precise pitch order. [0002] The invention also relates to a method for displaying tool paths defined by NC data as detailed A collection of segments or an endpoint to append to. [0003] The invention further relates to a method for displaying improvements based on data delineated in a five-axis system, which additionally includes A and B axes of rotation. Background technique [0004] For machining surfaces with complex shapes, including mold machining, NC-controlled machine tools are employed in a wide range of machining applications. For example, by using NC data prepared in CAD / CAM, any machining device such as an automatic tool-changing NC machine tool capable of high-speed tool fee...
