specific Embodiment approach

[0020] The specific implementation of the present invention is described in conjunction with the accompanying drawings: a virtual axis numerical control programming method of a universal angle milling head of the present invention, comprising the following steps:

[0021] a. Set the theoretical position of the virtual axis of the milling head, and set the value of the acute angle α formed by the tool axis and the horizontal plane according to actual needs. The position of the tool axis at this time is the theoretical position of the virtual axis;

[0022] b. Determine the theoretical deflection position of the tool. According to the angle α value and the tool length L' where the virtual axis is located, the deviation value ΔY in the vertical direction and the deviation value ΔX in the horizontal direction of the tool tip are obtained, so as to determine the position of the tool tip, and then get The theoretical deflection position of the tool;

[0023] c. Calculate the gap ΔL ...

Abstract

The invention provides a universal angular milling head virtual axis numerical control programming method and relates to a milling head programming method. The method aims at solving the problem that machining can not be achieved by a machine tool through a numerical control programmed program because of the adoption of the principal axis direction which can not be achieved or defined by the machine tool in the use process of a universal angular milling head. The method specifically includes the following steps that the theoretical position of the virtual axis of the milling head is set, the theoretical deflection position of a tool is determined, a gap between a tool bit and a workpiece is calculated, tool length compensation is conducted, the program is executed, and the tool starts to work. The method is applied to a numerical control milling machine which can not achieve special angle machining, four-axis machining can be achieved by a three-axis machine tool, five-axis machining can be achieved by a four-axis machine tool, numerical control programming application problems of the universal angular milling head are solved, and the use range of the machine tool is expanded.

Description

technical field [0001] The invention relates to a programming method of a milling head, in particular to a numerical control programming method of a virtual axis of a universal angle milling head, and belongs to the technical field of numerical control programming of a universal milling head. Background technique [0002] The right-angle milling head is a machine tool accessory, also called a transverse milling head or a horizontal milling head, which is used to change the output direction of the normal spindle of the machine tool so that the output of the tool is at a 90° angle to the spindle. It can realize the vertical and horizontal conversion of the machine tool, which is used to process the side of the workpiece, reduces the number of clamping of the workpiece, and improves the machining accuracy and efficiency. And the universal angle milling head (see figure 1 ) can make the output axis of the tool and the main shaft form any angle, even greater than 90°. [0003] ...
