Common problems and improvement methods in CNC machining customization process

From the specific consideration of production and manufacturing, the article summarizes the common situations and improvement methods in the whole process of CNC machining customization, and how the three key elements of speed, cutting amount and turning depth are adopted in different application levels, for your reference.

  1. Over-cutting the product workpiece
    Cause Analysis:
  2. Sliding away, the compressive strength of the CNC tool is insufficient, too long or too small, causing the CNC tool to bounce.
  3. Improper use of the operator.
  4. The turning capacity is uneven (eg: 0.5 left on the side of the bevel and 0.15 on the bottom edge)
  5. The main parameters of turning are not good (such as: the work difference is large, the SF setting is too fast, etc.)
    Improve:
  6. Knife standard: it can be big or small, short or long.
  7. In addition to the cleaning process, the capacity should be kept as symmetrical as possible (the capacity of the side and the bottom should be kept the same).
  8. Change the main parameters of turning rationally, and round the corners with large capacity.
  9. Using the basic functions of CNC lathe SF, the operator adjusts the speed to improve the actual effect of CNC lathe turning.
    Second, the situation
    Cause Analysis:
  10. The operator is not precise when using it manually.
  11. There are burrs around the mold.
  12. The centring rod is magnetic.
  13. The two sides of the mold are not vertical.
    Improve:
  14. Manual use should be repeated carefully and carefully, and the points should be at the same height as possible.
  15. Use a whetstone or a file knife to deburr around the mold, wipe it with a rag, and finally check it by hand.
  16. Demagnetize the centring rod before centring the mold (the centring stick can be divided by porcelain or others).
  17. Check whether the two sides of the mold are vertical (the vertical angle deviation is large, and the fitter detection method is required).
    Third, the knife situation
    Cause Analysis:
  18. The operator is not precise when using it manually.
  19. The CNC tool clamping is incorrect.
  20. The cutter head on the flying knife is incorrect (the flying knife itself has a corresponding deviation).
  21. There is a deviation between the R knife and the flat bottom knife and the flying knife.
    Improve:
  22. Manual use should be repeated carefully and carefully, and the knife should be set at the same point as possible.
  23. When the CNC tool is clamped, it should be blown clean with an air gun or wiped with a rag.
  24. The cutter head on the flying knife needs to measure the cutter bar, and one cutter head can be used when the bottom edge is smooth.
  25. An independent tool setting process can prevent the deviation between the R knife and the flat knife flying knife.

The above are the common problems and solutions of popular science from lathe processing custom manufacturers.
