Abstract

The invention discloses a Z-direction reference plane detection and setting method for a vertical milling machine. A probe is used to align and calibrate the reference processing plane. Before measurement, the profile of the bit plane is determined on the tooling according to the size and position of the blank of the part, and the profile of the positioning plane is used as the boundary. According to the position of the positioning surface of the part, a number of sampling points are selected as the sampling positions, and within the tolerance range, the average value of the Z values ​​of the sampling points is taken as the position of the Z-direction reference plane. The problem of slow speed, poor reliability, and low precision of the coordinate system Z toward the initial origin.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method for detecting and setting a Z-direction reference plane of a vertical milling machine. Background technique [0002] Machining technology generally follows the "positioning-processing" operation mode. According to this mode, how to follow the design and process [0003] It is required to realize the precise positioning of the workpiece to be processed and establish the corresponding processing coordinate system has become the most important work content in the processing process. When establishing the processing coordinate system, the alignment and setting of the Z-direction reference plane are the first steps. At this stage, for [0004] For vertical machine tools, the manual alignment method is the most commonly used method. During alignment, the operator uses a standard tool setting block to manually set the tool on the machine tool to find the po...
