Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 5 As shown, the workpiece to be processed is at the junction of the horizontal groove 2 and the arc groove 1, and the arc groove 1 is tangent to the horizontal groove 2. The milling cutter adopted in the present invention is an end mill or a ball end milling cutter whose radius is smaller than the width of the arc groove to be processed. The processing method of the axially changing space arc groove of the present invention comprises the following steps:

[0023] Step 1. The starting point of the outer edge of the arc groove 1 to be processed is the origin O, the horizontal radial feed direction of the milling cutter is the X axis, the axial feed direction of the milling cutter is the Z axis, and the vertical diameter feed direction of the milling cutter is Y-axis, establish a space rectangular coordinate system; define the...

Abstract

The invention discloses a method for machining axially changed spatial arc slots, which relates to the field of machining spatial arc slots of bogies for railway vehicles. According to the method, in the process of arc interpolation, an arc is divided into multiple line segments, and in a linear interpolation mode, feeding is performed in a machining plane along the axial direction parallel to a tool, so that the machining of a spatial arc is realized; in the process of interpolation, a system automatically computes the radius parameters of the tool, so that a problem that the system can not compute the radius of the tool and a spatial arc can not be interpolated in the axial direction due to axial changes is solved, so that the efficiency and the machining quality are improved. The method disclosed by the invention is particularly applicable to an arc machining mode that under the condition that a space or a tool is restricted, arc interpolation can not be performed in a direction perpendicular to a machining plane.

Description

technical field [0001] The invention relates to the field of machining space arc grooves of rail passenger car bogies, in particular to a machining method for axially changing space arc grooves. Background technique [0002] In workpiece processing, circular interpolation is a frequently used process method. The traditional process uses G02 (clockwise arc / circle cutting) and G03 (counterclockwise arc / circle cutting) along the direction perpendicular to the processing plane. to process arcs. In special cases, due to space or tool constraints, it is impossible to perform circular interpolation in the direction perpendicular to the machining plane. At this time, it can only feed along the axial direction parallel to the tool in the machining plane to process arcs. Since interpolation along the axial direction involves constant changes in tool length compensation, the corresponding processing instructions cannot be given in the numerical control system to realize the processing...
