cnc parts processing matters needing attention

1. The basic principle of processing is incorrect

The key error of CNC parts processing is due to errors caused by similar machining fitness exercises similar cutter wheel corridors. Because the basic principle of processing is incorrect, it is called an error of the basic principle of processing. If the critical error is within the allowable scale, the treatment of such varieties will still work.

2. Geometric errors of CNC lathes

The production equipment makes production errors, device errors damages in the entire process immediately damage the machining accuracy of the workpiece. It mainly includes the fitness movement of the turning axis of the lathe, the uniform linear motion of the slide rail of the CNC lathe the error of the transmission gear of the CNC lathe.

3. Production errors damages of special tools

Production errors in the production process of CNC parts processing tools, device errors damages all damage the machining accuracy of the workpiece. In the whole process of laser cutting, the cutting edge, drilling surface its workpiece cutting form significant friction, which may cause tool damage. When the special tool is damaged to a fixed value, the roughness value of the workpiece increases, the color harmony attitude change of the integrated ic are accompanied by a sensation. Tool damage will immediately damage the drilling output rate, processing quality cost.

4. The tooling fixture is incorrect

The errors of tooling fixtures for CNC parts processing include positioning errors, clamping errors, tooling fixture device errors tool setting errors. The key to this error is related to the production of tooling fixtures the accuracy of the assembly line.

5. The machining precision of CNC lathe parts is perfect. If the errors are controlled within a certain scale, it will be easy to have practical significance. Special tools produce production errors damage.

6. Incorrect positioning

The positioning error includes a reference to an undirected error a locator-produced error. When machining parts on a CNC lathe, several geometric primitives on the workpiece must be selected as the positioning reference for part processing. It is assumed that the selected positioning reference design basis are used (reference is used to clarify the appearance specifications parts on the part drawing). Assuming that a misdirection occurs, a reference misdirection error will be formed. The positioning pair of the workpiece positioning surface layer the fixture positioning member occurs once. The positioning part is accurate, the large deviation of the workpiece formed by the pair of open spaces in the center is called positioning. The inaccuracy of sub-production is incorrect. Inaccurate errors in positioning production are only formed when using the conditioning method, are prone to occur during the whole process of trial cutting.

7.Incorrect conditioning.

In each production process, the whole process system software is conditioned by a certain method beginning to end. Since the conditioning is unlikely to be accurate, it results in a conditioning error. In the processing system software, according to the adjustment of the CNC lathe, the tooling fixture the workpiece to ensure the mutual position accuracy of the workpiece the tool on the CNC lathe. When the initial accuracy of CNC lathes, cutters, tooling fixtures workpiece blanks considers the rules of the craftsmanship does take into account the daily dynamic elements, conditioning errors play a fundamental role in processing errors.

8. Measuring errors

When measuring parts accurately during production after processing, accurate measurement accuracy is immediately compromised by test methods, measuring instrument accuracy, workpieces, subjective factors. The above-mentioned seven kinds of processing errors can be prevented at a certain level, so it must be processed, the actual operation staff of the processing can more carefully more carefully detect the six production processes that will form processing errors during the entire processing process. After the actual processing operation, the damage of processing errors can be reduced as soon as possible.
