Abstract
A machining curve creating apparatus create curve of a tool used to machine a workpiece by repeating a procedure of taking, as a partial point sequence, a part of a point sequence expressing the tool path and generating a partial curve. The machining curve creating apparatus includes stored-information-utilized curve generating unit for generating a partial curve utilizing segmented curve information. When curve information utilization determining unit determines to utilize the stored information, the stored-information-utilized curve generating unit generates a partial curve.

A machining curve creating apparatus for creating a machining curve of a tool used to machine a workpiece by repeating taking, as a partial point sequence, a part of a point sequence expressing the tool path and generating a partial curve, the machining curve creating apparatus comprising:
- a curve information storage unit configured to store, for each of segmented curves that are individual curve sections providing the tool path, segmented curve information comprising a number of partial curves included in the segmented curve, a tangential direction at an end point of the segmented curve, and partial curve information comprising at least one of a partial curve length of each of the partial curves or a number of points of the partial point sequence and information that mathematically defines the partial curve;
- a curve information utilization determining unit configured to determine whether or not to use the stored segmented curve information when the partial curve is generated;
- and
- a stored-information-utilized curve generating unit configured to generate a partial curve utilizing the segmented curve information, and generate a partial curve, when the curve information utilization determining unit determines to utilize the stored information.
