【正文】 asure. (4) The output data processing results. The detection of Note: (1) The instrument should be accurate calibration before use. (2) The pitch error pensation, should be adjusted after pletion of the geometric precision machine carried out in order to reduce the geometric precision of the positioning accuracy. (3) for pitch error pensation of highprecision testing instruments should be used (eg laser interferometer) for measuring first and then the pensation should be repensated measurements and should be the appropriate analytical standards (VDI3441, JIS6330) on the measurement data analysis, until it reaches the machine tool positioning accuracy. Reposted elsewhere in the paper for free download. (4) machine tools, pitch error pensation methods, including linear shaft rotary axis pensation and pensation for these two methods can be right linear axis and rotary table positioning accuracy of pensation, respectively. 3 Cutting Accuracy Checking the accuracy of machine tool cutting checks, under the conditions in the 重慶理工大學(xué)畢業(yè)論文 文獻(xiàn)翻譯 8 cutting tool geometry on the accuracy and positioning accuracy of a prehensive examination, including the individual machining accuracy and the processing of checking the accuracy of the cast iron specimen examination (standard carbide cutting tools use cutting) . Examination items generally include: boring hole dimensional accuracy and surface roughness boring shape and pitch accuracy, precision flat end milling cutters, side milling cutter on the side of a straight line accuracy, side milling cutter on the side of roundness accuracy, axis of rotation switch 900 side of the rightangle milling cutter precision, twoaxis accuracy. 4 References 1.
