The robot is fiber-optic Laser Cutting machine is the fashion of laser beam machining with higher demand of a kind of precision, usually, cent of error of robot Laser Cutting is not geometrical error for geometrical sum of errors. Among them geometrical error includes staff parameter error, the rough travel of department of academic and referenced coordinate and the error that actual and fiducial coordinate fastens, articulatory axes is spent, null deviation; Error of clearance of the stretch deformation that is not geometrical element to include joint and connecting rod, gear, positive drive, hot deformation. If had very good compensation to the geometrical error of machine of robot Laser Cutting, very precision can rise greatly, the ability when the application that raises very precision to specific need only considers to undertake is not the compensation of geometrical error. Want to raise the very precision of machine of robot Laser Cutting, can from two respects proceed with, it is to use the method that avoids an error, be aimed at all sorts of error sources of generation robot error namely, use tall accurate process instrumentation to machine a robot each component, combine tall nicety to assemble a technology to undertake constructional. 2 it is to use integrated compensation technology, use contemporary measurement namely method, the data that measures to place undertakes an analysis, complementary with proper compensation algorithm, undertake compensating reducing the goal of the error in order to achieve to the error of machine of robot Laser Cutting. Because the robot is fiber-optic the precision demand of Laser Cutting machine is very high, need uses a variety of methods to undertake the error is compensated integratedly. Use the method that avoids an error above all. In the structural design of the robot, use reasonable structure, make of the robot be out of shape as far as possible small. In machining production process, the processing technique that crucial part uses high accuracy and ship-fitter art. But this method moves to robot course, generation is reduced as a result of function of mechanical wear, component and the error that the element such as character of trends of component part oneself brings is helpless. Raise robot precision further next through compensating a technology integratedly. Namely the robot error that the basis measures actually, appropriate compensation algorithm introduces in robot model, will reduce the error of the robot, achieve improvement and the goal that raise robot precision.
