

Updates tool diameter register for irregular shaped tools or tools 
with a hole in the center of the bottom. 

This cycle is used to measure the diameter of irregularly shaped tools 
or tools with a hole in the center of the bottom.

Tool#

T

Tool number. (Required)
The T cycle parameter must be the same as 
the current tool in the spindle.

EstDiam

D

This is the rough diameter of the tool. 
(Required) The diameter specified in this 
cycle parameter should be larger than the 
actual diameter of the tool being measured 
but no more than 0.04" (1.0 mm) over. If 
you have a left-handed tool, you would give 
a negative value to the diameter so the 
spindle turns on in the forward direction.

DistDown

E

The incremental distance from the current 
Z Retract amount to go down along the side 
of the probe stylus when doing a diameter 
pick. The maximum E value is 0.55" (13.97 
mm) or the tool may crash into the probe or 
table. If you enter a value larger than 0.55" 
(13.97 mm), the control issues an error 
message. If E is not set, the cycle uses a 
default value of 0.1" (2.54 mm). (Optional) 
[Default: 0.1"]
Ball nose cutters and special cutters that 
require a move down more than 0.55" 
(13.97 mm) are not supported.
NOTE: Z Retract Amount is set in the Tool 
Probe Parameters.

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.
