(1) CNC turning technology first thing to consider is the rationality of the parts map. Mainly in three aspects of analysis, that is, the size of the parts on the scale method is appropriate and CNC machine tool processing requirements, analysis of node coordinates calculation and analysis of the accuracy of the parts and technical requirements.

(2) whether the dimension method on the part drawing is suitable for the processing requirements of the CNC machine, which determines the rationality of the machined parts. The dimensions of the parts are given directly under the same reference, so that the design, process, measurement and programming origin can be unified stand up. This avoids unnecessary trouble and simplifies the various programming calculations.

(3) analysis of node coordinates calculation, in the processing of parts, including manual programming and automatic programming, in the manual programming to calculate the coordinates of each node, in the automatic programming will have to define all the geometric elements. Therefore, in the analysis of the parts diagram, to analyze the calculation of node coordinates.

(4) Analysis of the accuracy and technical requirements of the parts to be processed, you want to choose a reasonable parts processing methods, clamping methods and cutting costs, etc., must analyze the specific size of parts with superb technical level. Take full account of the various possibilities, if not achieve the desired effect of the remedial measures, in the established goals to complete all the links, and timely changes in accordance with the actual situation cutting speed, in any case to ensure the quality of work, the fact is, Do not cover the truth.
