In a method of generating a numerical control program in which, based on sectional shape data of a product to which a relief processing is to be performed, a numerical control program for turning-processing the product is generated in order to recognize a groove shape data existing in the vicinity of a corner as a relief sectional shape, wherein groove shape data is extracted from the sectional shape data, an intersection of a line segment parallel to a turning axis and a line segment that is not parallel to the line segment is calculated as a corner of the sectional shape data, and the groove shape data is recognized as a relief sectional shape in a case where dimensions of a frame which includes from the corner to the groove shape data are within predetermined dimensions.

A level difference or a uncut portion is prevented from being left between adjoining worked regions without forming any useless worked region. A lathe sectional shape forming unit () produces a sheet model of a lathe sectional shape in an X-Z plane on the basis of the solid model of a lathe shape formed by a lathe shape forming unit (). A first/second step working sectional shape forming unit () produces sheet models of the worked sectional shapes of the first step and the second step on the basis of the sheet model of the lathe sectional shape, a step dividing position and an overlap amount. A first step disused shape deleting unit () and a second step disused shape deleting unit () delete the shape needing no work, from the sheet models of the worked sectional shapes of the first step and the second step.
