Cutting data calculator
Application
With the cutting data calculator you can calculate the spindle speed
and the feed rate for a machine process. Then you can load the
calculated values into an opened feed-rate or spindle-speed dialog
box in the NC program.
Do not use the cutting data calculator if you have
programmed the
M136
function. With the
M136
function the TNC move the tool at the feed rate
F
in millimeters/spindle revolution as specified in
the program, but the cutting data calculator always
calculates feed rate in mm per minute.
To open the cutting data calculator, press the CUTTING DATA
CALCULATOR soft key. The TNC shows the soft key if you
open the pocket calculator (CALC key)
open the dialog field for spindle speed input in the TOOL CALL
block
open the dialog field for feed rate input in positioning blocks or
cycles
enter a feed rate in manual operation (F soft key)
enter a spindle speed in manual operation (S soft key)
The cutting data calculator is displayed with different input fields
depending on whether you calculate a spindle speed or a feed rate:
Window or spindle speed calculation:
Code letter
Meaning
R:
Tool radius (mm)
VC:
Cutting speed (m/min)
S=
Result for spindle speed (rev/
min)
Window for feed rate calculation:
Code letter
Meaning
S:
Spindle speed (rpm)
Z:
Number of teeth on the tool
(n)
FZ:
Feed per tooth (mm/tooth)
FU:
Feed per revolution (mm/rev)
F=
Result for feed rate (mm/min)
