The importance of shenzhen precision machinery parts processing nc programming in the process of precision machinery parts processing, precision parts
with process has a lot to do, what are the specific impact?
In this paper, we mainly discuss the numerical control programming, and the influence of geometric accuracy.
Precision metal processing is dependent on the CNC machine, operators need to application of nc programming to realize the control of the machine tool, so the numerical control programming that is particularly important, has a very big influence on the precision of parts processing.
Mainly reflects in the following respects.
First of all, should determine the origin of programming, CNC programming when its origin to choose whether or not appropriate, affect the accuracy of precision metal processing, it can avoid the machining error caused by the conversion;
Second, operators need to do a good job of programming data processing in the system, the reasonable degree of precision parts contour precision of trajectory;
In addition, in this link node calculation for programming, and then choose the correct processing road;
Finally, the operator to select the appropriate interpolation method, thus to reduce to a certain number, the machine will appear the phenomenon of dislocation and mobile, which affect the accuracy of precision metal processing.
In the process of parts processing, part of the job is done by human operators, such as cutting and polishing, etc. , this will inevitably have a certain degree of deviation, resulting in precision machinery parts processing will also appear when the error of the geometric accuracy.
The precision of the cutting tool will affect the precision of the parts, cutting tool in cutting, the blade and the blade can produce friction and parts, over time, the cutting tool will appear a certain degree of wear and tear on the wear area is larger, the friction between cutter and part value will increase, cutting tool in the work of the vibration amplitude will increase, lead to changes in the shape of precision metal cutting processing.
In order to solve this problem, technical personnel need to increase the degree of tool wear and installation accuracy, in the process of daily use, intensify of tool maintenance and repair, to compensate the wear parts in the compensation device used in it, and machine tool in the process of precision machinery parts processing is in a constant state of operation, the spindle rotation error in the long run will now, in the case of spindle axis deviates from the standard, the relative position of parts processing will change, thus affecting parts surface smooth degree, cause error within the precision of parts.
In order to solve the above problems, the operating personnel should strictly carry out of the machine tool spindle installation work, and in the daily processing timely maintenance of the spindle, adjust its operating position on a regular basis.
