Acu-Rite CNC 3500i User Manual

7 Programming: Canned Cycles, sub-programs



Updates tool-length register. To be used for large face mill style 
tools or shell mill tools that have a hole in the center of the bottom 
of the tool. 

This cycle is used to measure the length of large face mill style tools 
that have a hole in the center of the bottom of the tool. 

Tool#

T

Tool number. (Required)
With only the T parameter present, the 
spindle turns on in reverse and the canned 
cycle comes straight down measuring the 
tool length and storing it in the tool-length 
register. The T parameter must the same as 
the current tool in the spindle.

EstDiam

D

This is the rough diameter of the tool and is 
only used in this cycle to determine if the 
spindle should be turned on in reverse or 
forward. If you have a left-handed tool you 
would give a negative value to the 
diameter. If this parameter is left off, the 
control always turns on in reverse by 
default. (Optional)

OvrMed
Feed

M

This is the override for the medium 
feedrate that was set in the machine setup 
parameter ZFirstPickFeedRate_Medium. 
Sometimes there may be a tool that has a 
large diameter making it necessary to slow 
it down to prevent the touch probe from 
being hit too hard. This can only be set 
slower. Trying to set this higher will result 
in the software using the original feedrate.
