Machining simulation device and recording medium recording machining simulation program

Abstract

The invention provides a machining simulation device and a recording medium for recording a machining simulation program, which can visually output an overall difference of a machining result. This machining simulation device (1) virtually executes CNC programs and simulates machining results, and is provided with: a 3D model generation unit (12) that virtually executes a plurality of CNC programsand generates respective 3D models on the basis of the obtained machining results; a reference position specifying unit (14) that specifies, as a reference position, a predetermined coordinate commonto the generated plurality of 3D models; an overlay model generation unit (15) that generates an overlay model in which a plurality of 3D models are overlaid at a reference position; a difference model generation unit (16) that generates a difference model in which the difference of the 3D graphics in the generated superimposed model is acquired; and a display control unit (21) that controls thedisplay of the generated superimposed model and / or differential model.

Description

technical field [0001] The present invention relates to a processing simulation device and a recording medium recording a processing simulation program. Background technique [0002] Conventionally, it is known that a CNC (computerized numerical control) program is used to perform machining in industrial machines including industrial robots and machine tools. In an industrial machine, by displaying a plurality of CNC programs, differences in the CNC programs can be confirmed. [0003] However, the CNC program is composed of numerical values ​​or character strings, and it is not possible to visually know what kind of difference occurs when machining is actually performed. In addition, since a large number of settings are described in the CNC program, even if a part is changed, processing will be carried out unconsciously. Therefore, a numerical control simulation device capable of visually knowing a machining result by simulating a machining process has been proposed (for e...

[0003] However, the CNC program is composed of numerical values ​​or character strings, and it is not possible to visually know the machining results as to what kind of difference will occur when machining is actually performed.

In addition, there are many settings described in the CNC program, so even if a part is changed, processing will be performed unconsciously
