Embodiment Construction

[0016] The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention, all equivalent technical solutions also belong to the category of the present invention, and the patent protection scope of the present invention should be defined by each claim.

[0017] In order to explain more clearly how the program OFFSET realizes its function during execution, the working process and results of the software will be illustrated in the form of a view. Assume that the milling head is at 0° orientation. That is, the spindle end of the milling head faces image 3 The positive direction of the X axis of the machine tool.

[0018] First: After the gantry milling machine is installed with the accessory milling head, it will be as follows figure 2 As shown, the center above the milling head is the center of the machine tool spindle. When the workpiece is installed, the zero point of the workpiece coordinate syste...

Abstract

The invention discloses a program control method of a pentahedron of a numerical control plano milling machine. The method comprises the following steps: firstly, automatically setting numbers, angles and positions on a plurality of auxiliary cutter heads; deviating and rotating the coordinate axes of the auxiliary cutter heads according to the angles and the positions, and then converting into a coordinate axis rule conforming to a numerically-controlled machine tool theory; respectively setting the main shaft center and the cutter packing surface of the auxiliary cutter heads, and then determining a new coordinate system of workpieces and the zero position of the coordinate system; and finally deviating so that the zero point of the coordinate system is superposed with the zero point of the coordinate system of the workpieces, which is determined by a machine tool spindle. A software program solves the automatic conversion of the coordinate system in four positions of the right-angle cutter heads, solves the automatic conversion of the coordinate system in any angles of the universal-angle auxiliary cutter heads, ensures no need of resetting a center to determine the zero point of the coordinate system of the workpieces after the auxiliary cutter heads are assembled, meets the precision requirement of relative position of any plane or slope of some workpiece, and effectively controls the geometric tolerance in processing the workpiece.

Description

technical field [0001] The invention relates to a program control method, in particular to a pentahedron program control method for a large-scale numerically controlled gantry milling machine for processing product parts with complex structures and many cavities. Background technique [0002] In the field of machinery manufacturing, with the development of CNC machine tools, the processing efficiency is continuously improved and the product quality is getting better and better. Large-scale gantry milling machines are becoming more and more popular in heavy industry, and their status is becoming more and more important. Due to the particularity of the gantry milling machine structure, it must be equipped with various accessory milling heads to expand the processing range of the machine tool. For example, in the current field of marine low-speed diesel engine manufacturing, due to the complex structure of product parts and many cavities, this large-scale gantry milling...
