I have a SCMI Pratix 48cnc machine, and I have a customer I am cutting cabinet parts for. The customer is looking to have 5/8 melamine cut. The cuts on the melamine are clean (no chipping top or bottom), however when the cabinet is assembled it doesn’t pull together tight.
The drywall screws are being used on a 24" side, and three 8mm do-wells are used only to line the sides up. The box is not being clamped, and the cnc is producing a rough cut on the particle board, which that is the reason the cabinets won't go together tight. Does anyone have any thoughts?
From contributor F:
I used to cut melamine parts on a cnc with a single flute carbide bit. It is certainly possible that a dull bit will leave little ridges on the parts edges. The cure, for this case, is to keep an eye on the cut quality and change to sharp bits when necessary.
Try running a flush trim router bit over both edges of a set that won't pull up tight, and then check the fit. That will tell you immediately if it is on your end.
