Embodiment Construction

[0028] Next, preferred embodiments of the automatic programming device and method according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to this embodiment.

[0029] In this embodiment, for the complex chamfering target part shape on the curved surface, even without using a 5-axis processing machine, the rotation axis parallel to the central axis of the curved surface as the material shape and the bottom surface of the processing area shape are used. The machining in the 2-axis direction of the linear axis also realizes the chamfering process that maintains approximately the same chamfering width within the allowable accuracy.

[0030] figure 1 It is a block diagram schematically showing the functional configuration of the automatic programming device according to this embodiment. The automatic programming device generates control command data based on processing unit data for local processin...

Abstract

An automatic programming device provided with: a machining area shape-generating unit for generating machining area shape data, which is the shape of the machining area to be machined using machining unit data; and a chamfering tool path-generating unit for generating, when the machining area shape is a region to be chamfered, chamfering tool path data for the chamfering from chamfering data, which includes machining area shape data, data on the tool used, and data on machining conditions. When chamfering the boundary area between a machining area shape, which is defined on a curved surface that is a raw material shape, and the raw material shape, the chamfering tool path-generating unit generates, as chamfering tool path data, a machining path for achieving the chamfering by machining in two axial directions: a rotation axis parallel to the central axis of the raw material shape; and a linear axis parallel to the bottom surface of the machining area shape.

Description

technical field [0001] The invention relates to an automatic programming device and method. Background technique [0002] As an automatic programming device, the processing unit data for local processing including data such as the shape of the processing area, processing method, tool used, and processing conditions are input, and the machine tool is generated based on the input processing unit data. Control command information. In the automatic programming device, the chamfering process mainly refers to the process of removing the corners of adjacent surfaces and boundary portions where the surfaces intersect. When chamfering is performed on a curved surface, since the boundary between the curved surfaces is the object, the shape of the chamfered portion becomes complicated, so chamfering is usually performed by a 5-axis control machine or the like (for example, refer to Patent Document 1). [0003] In addition, chamfering can only be done by removing the corners in most c...
