Cutting data calculator
Application
With the cutting data calculator you can calculate the spindle speed
and the feed rate for a machining process. Then you can load the
calculated values into an opened feed rate or spindle speed dialog
box in the NC program.
To open the cutting data calculator, press the
CUTTING DATA
CALCULATOR
soft key. The TNC shows the soft key if you
open the on-line calculator (press the
CALC
soft key)
open the dialog field for spindle speed input in the T block
open the dialog field for feed rate input in positioning blocks or
cycles
enter a feed rate in manual mode (press the
F
soft key)
enter a spindle speed in manual mode (press the
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 rate per revolution (mm/1)
F=
Result for feed rate (mm/min)
You can also calculate the feed rate in the T block
and automatically transfer it to the subsequent
positioning blocks and cycles. For this purpose, with
feed rate input in positioning blocks and cycles, press
the
F AUTO
soft key. The TNC then uses the feed
rate defined in the T block. If you have to change the
feed rate later, you only need to adjust the feed-rate
value in the T block.
