A method of hole location based on graphic file for machine tool

Abstract

The invention discloses a method for locating a hole position of a machine tool based on a graphic file, comprising the following steps: A. Definition of a color pattern: defining a height plane position data for each color pattern and saving it in a database; B. Locating the hole position: b1. Obtain the target graphic file; b2. Collect the color pattern data in the file, and match the color pattern with the color information in the database to obtain the matching height plane position data; b3. Determine whether the color pattern is a hole pattern, if so , go to the next step, if not, discard and continue to collect the next color pattern data; b4. Collect hole center coordinate data and aperture data of the hole pattern; b5. Send all the data information of the collected hole pattern to The storage end is saved, and the collection and judgment are repeated until all color pattern judgments are completed; C. Hole position sorting to determine the hole position processing order. By adopting the above method, it has the advantage of being able to accurately locate the position of the hole on the special-shaped machining surface of the workpiece.

Description

technical field [0001] The invention relates to the technical field of numerical control system processing, in particular to a method for locating a hole position of a machine tool based on a graphic file. Background technique [0002] Automatic machine tools such as automatic drilling machines, automatic tapping machines, CNC milling machines, tapping, drilling and milling machining centers, etc., and the processing platform in the automatic machine tools will define the horizontal plane as the plane formed by the X axis and the Y axis, while the Z axis is the plane formed by the X axis and the Y axis. Represents the height direction. When drilling or tapping on the surface of the workpiece, the processing program is generally compiled by the programmer himself. This method requires the programmer to compile the hole positions of each hole one by one. Therefore, when the number of holes is small It can be easily adjusted. However, when there are many holes, it will take a l...

Problems solved by technology

However, when the machined surface of the machined part is a non-planar curved surface or stepped surface, due to the irregularity of the machined plane, although the CAD drawing can locate the hole position of the machined part's overlooking angle, the machining tool head of the machine tool , such as a drill tap, but it cannot be in good contact with the machined surface of the machined part, so as to control the torque of the machined tool head and the depth of machining well, so the program generated directly based on the X and Y coordinates cannot be used, or It can only be used by manually modifying or separating multiple production programs according to the Z-axis height
