Operation Manual
All tool lengths originate from datum. There are several different ways to establish
datum, such as “touching off” with an empty spindle, using a repeatable standard or
using an electronic edge finder (refer to Establishing Datum).
If you begin setting the tool length offsets by setting Datum using an electronic edge
finder it must have a fixed and repeatable length. The current tool information can
not have a length value. All of the tool length offsets in the program will be the dif
ference in length between the tool and the edge finder.
When defining tool length offsets in the Tool Step, touch each tool to the same sur-
face and press the
TEACH TOOL LENGTH softkey to establish the tool length.
Once you have identified the tools you will be using, you can program the length
offsets into the tool steps.
Entering the first tool
Decide on a method that will be used to set the Z-axis datum. You can choose to set
the Z-axis datum with the spindle nose (without a tool inserted), using a repeatable
standard, or using a 3-D electronic edge finder. To begin your Tool Library, set the
current tool information in the status bar so the tool length is zero. In this example,
you will begin with the spindle nose to set datum zero. If you wish to use the ACU-
RITE 3-D Electronic Edge Finder, or a tool holder with a repeatable standard, then
place it into the spindle instead.
