E-26 PREPARATION BEFORE STARTING MASS PRODUCTION
<Example>
If the workpiece is machined to 50.35 mm diameter
although the program is intended to machine it
50 mm, follow the steps indicated below. Assume
that the tool command used for this machining is
T0101 (tool wear offset number 1).
a)
Move the cursor to the X-axis offset data field
for the wear offset number 1.
b)
Calculate the wear offset data.
[Programmed diameter]
−
[measured diameter]
= [offset data]
50.0
−
50.35 =
−
0.35
c)
Since the diameter is machined 0.35 mm
larger than the programmed diameter, the
offset data should be input to machine the
workpiece 0.35 mm smaller.
Input "
−
0.35" using the data entry keys.
d)
Press the
[+ INPUT]
soft-key.
1.
If the INPUT key is pressed, the value
having been input with data entry keys is
input for the tool wear offset data.
Therefore, make sure to press the
[+
INPUT]
soft-key.
2.
Make sure that the decimal point and the
plus or minus sign are input correctly.
24)
Select the memory mode (
) with the mode
selection switch.
25)
Display the PROGRAM (memory) screen, and
locate the head of the program.
26)
Make sure that the cursor is at the head of the
program.
27)
Close the front door.
