SECTION 5 S, T, AND M FUNCTIONS
To drill two 15 mm dia. holes, create a program as indicated below:
LE33013R0300700070003
•
Calculate the feedrate (mm/min) for drilling with the equation below:
Feedrate (mm/min) = Tool speed (rpm) x Feedrate (mm/rev)
Therefore, when the tool speed is 400 min-1{rpm} and the feedrate is 0.1 mm/rev, the feedrate
(mm/min) is calculated as:
F = 400 x 0.1 = 40 mm/min
•
When an end mill is used, its feedrate (mm/min) is calculated with the following equation:
Feedrate (mm/min) = Tool speed (rpm)
Feed (mm/blade)
Number of end mill blades
•
Assuming an end mill with four blades (flutes) is used at 300 min-1{rpm} and a feedrate of 0.05
mm/blade, the feedrate (mm/min) is
F = 300 x 0.05 x 4 = 60 mm/min

Continued from turning operation program
Indexes C-axis in the positive direction.
The spindle indexes at the 90
°
position
in positive direction and the drill is
positioned near the workpiece surface
at the rapid feedrate.
Designates the spindle as the C-axis.
Feedrate in mm/min mode is selected.
The drill starts rotation at 400 min
-1
{rpm}
in the leftward direction.
After thespindle is clamped, 15 mm dia.
hole is drilled at a feedrate of
40 mm/min.
The drill returns to the commanded
point at the rapid feedrate.
The spindle is indexed at the 270
°
position after it is unclamped.
The second hole is drilled after the
spindle is clamped.
The M-tool stops and the turret returns to
the turret index position.
