Display device and processing system for swing cutting

Abstract

The present invention relates to a display device and machining system for wobble cutting. The display device includes a position information acquisition unit, a rotation information acquisition unit, a first waveform generation unit, a second waveform generation unit, and a waveform display unit. The position information acquisition unit acquires position information of the feed axis (M1) when intermittent cutting is performed. The rotation information acquisition unit acquires the rotation speed of the workpiece as the rotation information of the spindle when intermittent cutting is performed. The first waveform generator generates first waveform data representing a time-dependent change in the position information based on the time-series position information of the feed axis. The second waveform generation unit obtains the time per one rotation from the above-mentioned rotation speed, and divides the first waveform data into partial waveform data according to this time, so that each partial waveform data matches the start point of the first waveform data in time. move sequentially in the axial direction, thereby generating a plurality of second waveform data. The waveform display unit displays a plurality of second waveform data.

Description

technical field [0001] The invention relates to a display device of a machine tool for turning a workpiece through the cooperative action of a spindle and a feed shaft, in particular to a display device and a processing system for oscillating cutting. Background technique [0002] When machining a workpiece with a cutting tool of a machine tool, if chips are continuously generated, the chips may be entangled with the cutting tool. In such a case, in order to remove chips from the cutting tool, it is necessary to stop the machine tool, which takes time and reduces productivity. In addition, the workpiece may be damaged by chips, which may lower the quality of the workpiece. [0003] In order to avoid such defects, there is known an oscillating cutting in which a cutting tool and a workpiece are relatively oscillated in a machining direction to chop chips (for example, refer to Japanese Patent No. 5033929, Japanese Patent No. 5599523, etc.). A control device of a machine too...

Problems solved by technology

[0007] However, there is a problem that it is difficult to judge whether the tool can cut chips simply by displaying the command data or the time change of the actual position data related to the oscillating feed axis.
