Problems solved by technology

like Figure 11 As shown, when arc shape machining by scraping machining is commanded, even if the movement amount and feed speed in the X-axis direction, Y-axis direction, and Z-axis direction are corrected in advance using the above formula 1, the tool path Even if the circular interpolation is used, there will also be a problem that the cutting path is a skewed circular arc shape.

Embodiment Construction

[0044] below, with Figure 1 Embodiments of the present invention will be described first.

[0045]In the numerical control device of the present invention, if circular interpolation is commanded in the scraping process of the machining program, the path of the cutting point, the speed of the cutting point, the tool angle data, the effective tool nose data of the tool, and the actual machining The program block progress rate calculates the actual path and speed of the tool, and controls the machine. The numerical control device of the present invention relates to the control method of the tool path that considers the progress rate of the program block in the actual processing, not only can be applied to the cone angle processing and arc shape processing based on scraping processing, but also can be applied to other shapes The processing situation. Hereinafter, the case of performing circular-arc shape machining will be described as an example.

Abstract

A numerical controller capable of automatically calculating a tool path based on a command of a cutting path in skiving machining includes a command analysis unit that determines whether a block readfrom a machining program corresponds to a skiving machining command, a skiving machining command data calculation unit that calculates a path and a feed speed of a tool based on a path of a cutting point and a feed speed of the cutting point commanded by the skiving machining command when the command analysis unit determines that the block corresponds to the skiving machining command, and an interpolation unit that calculates interpolation data according to a progress rate of the block during actual machining based on the path of the tool calculated by the skiving machining command data calculation unit and a coordinate value during actual machining.

Description

technical field [0001] The present invention relates to a numerical control device, in particular to a numerical control device for controlling skiving processing. Background technique [0002] Scraping is a processing method in which, when cutting a work with a blade (bite), the work is cut by feeding the blade in the line direction of the work (JIS standard B0106 0.209). In the scraping process of a turning machine, a tool including a linear knife disposed obliquely to the rotation axis of a rotating workpiece is used, and the workpiece is machined while moving along the Y-axis (for example, Japanese Patent No. 3984052). [0003] When the above-mentioned scraping process is performed by the conventional numerical controller, it is necessary to command the movement of the Y-axis corresponding to the movement of the Z-axis. Figure 7 It is a figure which shows the cutting path of the cutting process with respect to a workpiece|work at the time of scraping processing, and the...
