Abstract

The invention discloses a robot constant-force polishing machining parameterized programming method based on UG NX secondary development. The robot constant-force polishing machining parameterized programming method comprises the following steps: establishing a three-dimensional simulation model of the curved surface revolving body part; opening UG NX10.0 through software compiled by a C # program; importing the three-dimensional simulation model of the curved surface revolving body part; and determining a machining coordinate system, decomposing a curved surface revolving body part grinding process, and establishing the relation between the contact area and the cutting depth; writing a parameterized interface by using C #; generating a motion trail coordinate file. cls by a teaching robot; assigning values in a tool path program, drawing track points, and conducting simulation machining through a parameterized interface, and distinguishing the grinding amount of a ground workpiece through colors, so as to judge whether the ground surface meets the requirement or not; and generating a robot language capable of being directly used for robot grinding machining through after-treatment. The robot constant-force polishing machining parameterized programming method has the characteristics of strong universality, high programming efficiency and good processing quality.

Problems solved by technology

[0002] The grinding and polishing of free-form surface parts with complex surfaces and high precision requirements such as aircraft engines, steam turbine blades, and abrasive tools is basically done by hand-held tools and relying on the experience of workers, which is difficult to guarantee the shape and position of free-form surface parts Precision, surface microscopic physical properties, and high manufacturing costs restrict the development of aircraft parts processing technology; especially the current manual work is difficult to ensure the consistency of quality and processing efficiency

[0003] Automatic grinding also faces many problems: 1) The grinding process is a complex process, and the research on its mechanism is not deep enough, which makes the grinding of free-form surfaces a weak link in mold production and manufacturing and restricts the development of the mold manufacturing industry. Bottleneck; 2) The surface to be processed is complex and diverse, requiring a flexible and adaptable way to control the grinding accuracy

[0004] At present, domestic automatic grinding and processing simulation software is not perfect, lacking the factors affecting the contact area of ​​constant force grinding, and there are no functions such as parameterized programming and 3D simulation.
