CNC machine tool geometric error and pensation method
Abstract: The geometric error C machine tools were the cause of a more detailed analysis, the system pensation methods were summed up, and on this basis on a variety of methods of pensation applications, in order to further the achievement of precision machine tools lay the foundation for soft upgrade.
Keywords: CNC machine tools; geometric error; pensation
Foreword
Improve the precision machine tool There are two ways. One is by improving the part design, manufacture and assembly level to eliminate a possible source of error is called error Prevention Act (error prevention). This method is the main subject on the one hand, the precision machine tool processing constraints, on the other hand, lead to improving the quality of parts processing costs of expansion, with the result that the use of this method are subject to certain restrictions. Another called pensation Act (pensation), usually by modifying the machine's processing instructions for pensation of machine tools, achieve the desired trajectory, precision machine tools to achieve a soft upgrade. Studies have shown that the geometric error and the error caused by the temperature of the overall error of machine tool about 70 percent, of which the geometric error is relatively stable, easy to carry out pensation. Geometric error C machine tools pensation, you can raise the level of processing machinery industry, the promotion of scientific and technological progress and improving China's national defense capability, in turn greatly enhance China'prehensive national strength are of great significance.
1 Geometric Error Causes
Generally agreed that the geometric error C machine tools from the following causes:
Machine Tool original manufacturing error
Machine refers to position of the ponents work surface geometry, surface quality, the position error between the machine ca
