Abstract
Provided are a numerical control device and a control method that enable simple true circular processing. The numerical control device is provided with: a true circular processing unit that, using an operative command, causes a cutting tool to perform true circular processing on a workpiece with a starting point set as a center; and a processing program calculation unit that, in order to give a command to a machining tool, calculates, as an operative command for the machining tool, a processing operation position from a single line processing program.
Claims4
A numerical control device comprising:
- a machining program computing unit that computes, as a command executable by a machine tool, a machining position from a one-line machining program for commanding the machine tool;
- and
- a true circular machining unit that performs true circular machining on a workpiece about a start point as a center with a cutting tool according to the executable command,
- wherein in a case where no cancellation code is commanded after commanding of the one-line machining program, when an optional position on a commanded plane is commanded, the commanded optional position is taken as the start point, and true circular machining on the workpiece is performed about the start point as a center with the cutting tool of the machine tool.
A numerical control device control method, comprising:
- a step of computing, as a command executable by a machine tool, a machining position from a one-line machining program for commanding the machine tool;
- and
- a step of true circular machining on a workpiece about a start point as a center with a cutting tool of the machine tool according to the executable command,
- wherein in a case where no cancellation code is commanded after commanding of the one-line machining program, when an optional position on a commanded plane is commanded, the commanded optional position is taken as the start point, and true circular machining on the workpiece is performed about the start point as a center with the cutting tool of the machine tool.
