Problems solved by technology

In the five-axis processing machine, because the number of axes is not enough, it is generally impossible to make the (Xf, Yf, Zf) direction of the feature coordinate system parallel to the (Xt, Yt, Zt) direction of the tool coordinate system
Regarding this situation, for example, in claim 1 of Japanese Patent Application Laid-Open No. 2005-305579, it is stated that a "rotation angle around the Z axis" occurs, which measures the (Xf, Yf) direction of the characteristic coordinate system from the tool coordinate system The (Xt, Yt) direction of the tool coordinate system is rotated, so the (Xf, Yf) direction of the feature coordinate system cannot be parallel to the (Xt, Yt) direction of the tool coordinate system

Embodiment Construction

[0037] Take the A-axis, B-axis, and C-axis as three rotation axes, and take the order of the A-axis, B-axis, and C-axis as the axis sequence from the tool to the worktable in the mechanical structure. When there are a plurality of table rotation axes, these axes intersect. When there are a plurality of rotation axes of the tool head, these rotation axes intersect and intersect with the tool center axis. The origin of the tool coordinate system is the intersection position of these rotation axes when there are multiple tool head rotation axes, and the intersection position between the rotation axis and the tool central axis when there is one tool head rotation axis. In addition, when there is no tool head For the rotary axis, it is the intersection position of the tool axis and the end face of the tool head. When there are multiple rotary axes of the worktable, take the intersection position of the rotary axes of the worktable as the origin (P0). The coordinate system that mo...

Abstract

The invention provides a numerical control device for a multi-axis processing machine used for a processing inclined plane. Inclined planes of a work piece are processed through controlling three linear axles relatively to a position of the work piece installed on the working table and controlling three rotary axles relative to a direction of the work piece. A three rotary axle operation part composed of an analyzing unit calculates positions of the three rotary axles to make a coordinate system (a knife coordinate system) on a knife and moving along with the movement of the knife to be parallel with a characteristic coordinate system indicating a coordinate system of the inclined plane on the work piece. The three rotary axle are driven to calculated positions.

Description

technical field [0001] The present invention relates to a numerical control device for controlling a multi-axis processing machine having at least three linear axes and at least three rotary axes. In particular, when machining an inclined surface of a workpiece on a table, the coordinate system of the inclined surface, that is, the feature coordinate system (feature coordinate system), is commanded, and the rotation axis is controlled so that the coordinate system on the tool, that is, the tool coordinate system, becomes consistent with the feature coordinate system. A numerical control device for directions parallel to the coordinate system. Background technique [0002] Japanese Patent Application Laid-Open No. 2005-305579 describes a method of machining an inclined surface on a workpiece, focusing on a five-axis machining machine composed of three linear axes and two rotary axes. Five-axis processing machines are roughly divided into three types: "tool head rotary type",...
