Changing to a Tool of unknown length when in the DRO
If you are using the DRO and need to set a new tool, follow the procedure below. Be sure to reestab-
lish the tool length offset for your program before running it as described below.
•
From the
DRO
view, press the
TOOL
key.
•
Enter the tool diameter, clear any length and if you wish, the type.
•
Press the
GO
key.
•
An Operator intervention message will appear asking you to “use” the selected tool.
•
Place the selected tool in the spindle.
•
Press the
GO
key to confirm that you have installed the tool.
•
Set the Z-axis datum following the instructions found in your operation manual.
At this point, your program’s tool length offsets are no longer valid. Follow the steps below to
reestablish the Z-axis datum and tool length offsets for your program.
•
From the
PROGRAM

•
Press the
GO

Changing to a Tool of unknown length in program
When running a program, it is easy to switch between tools of known length, to tools that have a
non-repeatable length such as a counter-bore held in an R-8 collet. For example, let’s say a program
is being run that has tool 1 -a center drill- in a repeatable holder, as the first step.
Step 2 in the program is a bolthole pattern.
Step 3 is a tool step using tool two-a drill- in a chuck that also repeats.
Step 4 is the same hole pattern repeated.
Step 5 is a tool step programmed as a counter bore of unknown length.
Step 6 is the same hole pattern repeated.
For this example, if two identical parts are being machined. The first part is in place and datum has
been set using tool one from the program as the current tool.
