Abstract
A tool path compensation device according to an aspect of the present disclosure includes: a tool path acquisition unit which acquires tool path information that specifies a tool path on which a tool machining a workpiece moves by way of a plurality of command points through which the tool should pass; a tool shape acquisition unit which acquires tool shape information that specifies a shape of the tool; a target shape acquisition unit which acquires target shape information specifying a target shape after machining of the workpiece; and a density adjustment unit which adjusts a density of the command points, so that the density of the command points becomes larger as curvature of the target shape increases.
Claims5
A tool path compensation device comprising:
- a tool path acquisition unit which acquires tool path information that specifies a tool path including a plurality of command points, the plurality of command points being points that a tool passes through when machining a workpiece;
- a tool shape acquisition unit which acquires tool shape information that specifies a shape of the tool;
- a target shape acquisition unit which acquires target shape information specifying a target shape after machining of the workpiece;
- and
- a density adjustment unit that adjusts a density of the command points, so that the density of the command points becomes larger as curvature of the target shape increases, by:
- determining a first deviation range of a portion of the tool path between adjacent ones of the command points to the target shape,
- determining a permitted value for the first deviation range, and
- adding command points between the adjacent ones of the command points until the first deviation range is less than or equal to the permitted value.
