Abstract: An apparatus that creates, based on shape data of an object to be machined and grinding allowance data for the shape data, a numerically controlled machining program that has the grinding allowance data reflected in the shape data, is configured to include storing means 2 and 4 that store the shape data of the object to be machined and the grinding allowance data; a shape data modification means 5 that modifies the shape data to create, based on the grinding allowance data, shape data having a grinding allowance; and a numerically controlled machining program creation means 6 that creates a numerically controlled machining program for the modified shape data, with the apparatus enabling easy and efficient creation of a numerically controlled machining program having the grinding allowance reflected in the shape data.

Abstract: A numerical control programming method is characterized by comprising: a machining unit editing step for generating an edited machining unit by editing, based on an input, at least one machining unit out of a plurality of machining units which configure a first machining program generated based on a first material shape model and a product shape model; a second non-edited machining unit generating step for generating a second non-edited machining unit which corresponds to a machining shape model having no duplication with a machining shape model which corresponds to the edited machining unit based on a first non-edited machining unit which is a machining unit other than the edited machining unit out of the plurality of machining units which configure the first machining program; and a second machining program generating step for generating a second machining program including the edited machining unit and the second non-edited machining unit.
