Kerf Compensation
Tracer controlled cutting of dimensional shapes
requires compensation for the kerf by the cutting
torch. Kerf compensation is accomplished by
offsetting the tracer head and cutting torch with
respect to the top template line edge.
The necessary kerf during cutting is determined by:
•
type of torch and nozzle used
•
type of fuel gas
•
material being cut
•
material thickness.
The most practical method to determine correct kerf
width is to make a cut in similar scrap material and
measure it.
Kerf offset range is determined by the lead of
the lens in the photocell tracer. Compensation is
adjusted by rotating the scanner in the housing
unit. Loosen the lock screw and adjust the reader's
position so that the torch is offset by ½ the kerf
width.
