Tool Tip:
Eliminate Wall Taper When Finishing
STEP 1:
Run a climb cut finish pass using speed, feed and step-over values (RDOC)
from the speed and feed charts. Adjust for tool projection if needed.
STEP 2:
Re-run the path using the same speeds and feeds but in a conventional cut
direction. Simply retrace the prior finish pass; do not program to remove
more stock. This skim pass, traveling in the opposite direction of the first
pass, will help eliminate wall taper caused by tool deflection during the first
pass.
D = Tool diameter
IPT = Inch per tooth
SFM = Surface feet per minute
Adjustments must be made to reduce chatter and maximize tool life when using
long length tools. The adjustments below are based on the total amount of tool
projection and use the speed and feed data found in the application charts for
each tool series.
