Abstract
Provided is a numerical value control device capable of easily setting an effective diameter for a machined circle. The numerical value control device is equipped with a command unit which prescribes a machined circle standard or a proportion of the tolerance class to the machined circle tolerance in a machining program for machining a circle using a machine tool, and also equipped with a setting unit for setting a correction amount for the effective diameter of the machined circle on the basis of the machined circle standard or the proportion of the tolerance class to the machined circle tolerance.
Claims6
A numerical control device comprising:
- an instruction unit that instructs a standard or tolerance class of a machining circle and a ratio of a tolerance of the machining circle in a machining program that causes a machine tool to perform threading or circular machining;
- and
- a setting unit that sets a compensation amount of an effective diameter of the machining circle based on the standard or tolerance class of the machining circle and the ratio of the tolerance of the machining circle,
- wherein the numerical control device controls a cutting tool of the machine tool to perform the threading or the circular machining based on the set compensation amount, and
- wherein the effective diameter is defined by Japanese Industrial Standards (JIS) or International Organization for Standardization (ISO).
