• Release the tool in the Z–axis direction without moving the X–axis and stop the spindle.
• Measure the diameter á of surface B. Set this value as the measured value along the X–axis for the desired
offset number in the same way as when setting the value along the Z–axis.
• Repeat above procedure for other necessary tools. The offset value is automatically calculated and set.
• For example, in case a=69.0 when the coordinate value of surface B in the diagram above is 70.0, set 69.0
[MEASURE] at offset No.2.
• In this case, 1.0 is set as the X–axis offset value to offset No.2.
Compensation values for a program created in diameter programming
Enter diameter values for the compensation values for axes for which diameter programming is
used.
Tool geometry offset value and tool wear offset value.
If measured values are set on the tool geometry compensation screen, all compensation values
become geometry compensation values and all wear compensation values are set to 0. If measured
values are set on the tool wear compensation screen, the differences between the measured
compensation values and the current wear compensation values become the new compensation
values.

Program checking in dry run single block mode

Objectives : At the end of this exercise you shall be able to
• load the program to run in auto mode operation
• check the program in dry run using single block mode.

Job Sequence

• Load the program to run in auto mode operation
• Keep the feed rate and rapid knobs to zero position.
• Press cycle start

• Press dry run and single block mode
• Open the rapid switch to 30%
• Press cycle start button, the execution of the program is stopped after the current block is executed.
• Press cycle start button to executeive next block.

• Similarly continued until the end of program that is M30;

Skill Sequence

Running program in auto mode/memory operation

Objectives : At the end of this exercise you shall be able to
• load the program to run in auto mode
• execute the program in auto mode.

Memory operation
Programs are registered in memory in advance. When one of these programs is selected and the cycle start
switch on the machine operator’s panel is pressed, automatic operation starts, and the cycle start LED goes on.
