Embodiment approach

[0034] figure 1 It is a figure which shows the structure of the numerical control apparatus provided with the interference detection apparatus concerning embodiment. The numerical control device 1 is a device that controls the NC machine tool 30 using an NC program. The numerical control device 1 checks whether each combination of components constituting the NC machine tool 30 , a tool (rotary tool) 4 , a material (not shown), and a jig (not shown) interferes (collides).

[0035] The numerical control device 1 performs intersection calculation using the respective 3-dimensional shapes of the components, the tool 4 , the material, and the jig, thereby simulating whether or not they interfere (interference check simulation). In order to check whether the tool 4 interferes with components other than the tool 4 , the numerical control device 1 of the present embodiment generates a three-dimensional shape of the tool 4 using image data of the tool 4 .

Abstract

Equipped with: a contour shape analysis unit (13) that analyzes the 2D image of the rotary tool to extract the contour shape and tool length of the tool cross section; a rotation center analysis unit (14) that analyzes the contour shape to obtain the rotary tool the center of rotation; the 3D rotation shape generating part (15), which generates the 3D shape of the rotating tool based on the contour shape, the tool length and the rotation center; and the interference check processing part (16), which uses the 3D shape check in use When the rotary tool performs NC machining on the workpiece, whether the rotary tool interferes with parts other than the rotary tool, the 3D rotary shape generating unit (15) generates the profile of the rotary tool using the left profile shape and the right profile shape The 3-dimensional shape, wherein the left contour shape is the contour shape to the left of the rotation center among the contour shapes, and the right contour shape is the contour shape to the right of the rotation center among the contour shapes.

Description

technical field [0001] The present invention relates to an interference inspection device and a numerical control device for inspecting the interference between a tool used in a working machine and other parts. Background technique [0002] Numerical Control (Numerical Control: hereinafter referred to as NC) device is a device that allows a machine tool to process a material (processed object) according to a processing program. Before the working machine starts processing, it must be confirmed that there is no collision between various parts when the working machine is moving. Therefore, an interference check simulation is performed beforehand. In this interference check simulation, it is checked whether or not any of components constituting the machine tool, tools, materials, and jigs used in the machine tool interfere with each other. In order to execute the above-mentioned interference check simulation, a 3-dimensional shape of a tool or the like is required. [0003] ...
