Successful CNC routing is evaluated by how well and how long your tool cuts.
Cutting successfully will give you outstanding part finish and long tool life between sharpenings if the tools are being used
to their optimum performance. This requires managing the chipload.
Chip load is simply defined as the thickness of a chip which is formed during the machining of a material.
Chip load is critical because if the chip is the proper size, it will carry away the heat promoting tool life. If the chip
is too small, the heat is transferred to the cutting tool causing premature dulling. Too high of a chipload will cause an
unsatisfactory edge finish, or part movement.
To increase Chip Load: To
decrease chip load:
Increase the feed rate
Decrease the feed rate
Decrease the RPM
Increase the RPM
Use less flutes
