Title:
METHOD OF CHECKING TOOL INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/1984/004479
Kind Code:
A1
Abstract:
A tool interference checking method is employed to check, beforehand, whether or not a tool (TL) will interfere with a workpiece (WK) when cutting the workpiece (WK), by moving the tool (TL) relative to the workpiece (WK) in accordance with NC data constituted by a plurality of blocks (B1 to B5). The method comprises the steps of: obtaining tool movement directions (+X, -Y, +X, +Y, +X) specified by the NC data for each block; obtaining a tool offset path (TCP) from the tool radius r and the NC data; obtaining tool movement directions (+X, -Y, -X, +Y, +X) for each block of the obtained tool offset path; making a comparison between the tool movement directions specified by the NC data and the tool movement directions specified by the tool offset path for each block; and judging that tool interference will occur when the tool movement directions do not coincide with each other within at least one block.
