Optimising parameter to set trims
Use this parameter to set a minimum rip trim on the front (leading edge) and rear of each board.
Allow for the saw blade thickness when setting this value.
A setting of 10mm removes a FULL 10mm of material from the board. If the saw blade thickness is set at 4.8mm the falling piece is (10 - 4.8), that is, 5.2mm. If the trim is set to less than the setting for the blade thickness, for instance 3mm when the saw blade is set at 4.8mm this produces a GRAZING cut. The material removed in this case is 3mm and is all lost as saw dust.
In inches a trim of 3/8in. with a saw blade thickness of 3/16in. creates a falling piece of 3/16in.
The trims are often necessary for squaring a board prior to accurate cutting but in some cases a trim is not required. Set either trim or both to zero if necessary.
Notes
- Can also be set as a Material parameter at both board and material level
