5.3 CUTTING FEED
Overview
Feedrate of linear interpolation (G01), circular interpolation (G02,
G03), etc. are commanded with numbers after the F code.
In cutting feed, the next block is executed so that the feedrate change
from the previous block is minimized.
M
Four modes of specification are available:
1. Feed per minute (G94)
After F, specify the amount of feed of the tool per minute.
2. Feed per revolution (G95)
After F, specify the amount of feed of the tool per spindle
revolution.
3. Inverse time feed (G93)
Specify the inverse time (FRN) after F.
4. One-digit F code feed
Specify a desired one-digit number after F. Then, the feedrate set
with the CNC for that number is set.
T
Two modes of specification are available:
1. Feed per minute (G94)
After F, specify the amount of feed of the tool per minute.
2. Feed per revolution (G95)
After F, specify the amount of feed of the tool per spindle
revolution.
