CNC Machining Recessed Panel MDF Doors9/3
Any tips on reducing CNC machining marks left on recessed panels of MDF doors?
There are a few types of things can help improve the cut quality. Can you post a picture of the type of cut quality you are getting off your machine?
The first would be the type of MDF you are using. Not all types produce the same finish when pressing.
Next would be to adjust the overlap on the tooling and also with the speed of machining. It also could be the spindle might need some fine adjustment to improve your cut quality. Manufacturers have their tolerances for spindle alignment, but it can usually be improved upon by taking the time to align a spindle.
The final step would be to control the climate for the MDF as it comes in, sits, machines and then presses. Humidity and temperature can all affect it and cause problems. Some have problems letting the board sit overnight prior to pressing. Some people don't, it depends on the climate.
when you say "Overlap is minimal" I presume you mean "stepover" if minimal is above 45% then consider changing it. I get far cleaner cuts and less heat on bit I can run faster as well
I noticed you mentioned that your direction of cut is clockwise. You may want to try cutting in a counter-clockwise direction. We have found tools not only last longer when cutting in a counter-clockwise direction, but the cut is much cleaner.
-Just a thought.
