4.2 Tool Data
 With the tool in the spindle, carefully jog the tool down until it
touches the top surface of the work piece. This is referred to as
“Part Zero”.
 Touch the Teach button. The 3500i calculates the tool
length offset for the selected tool putting the data to
the length column.
 Press the Enter button to save the data entered in the field.
Diameter Offset in Tool Table
When you activate a tool, you automatically activate the length offset
and diameter values recorded on the Tool Table. When a tool is
activated, the length offset is applied immediately to provide an
accurate Z-axis position display.
The active diameter value is important when you program
compensated moves and use cycles with built-in tool compensation.
If tool diameter is correct, compensated moves and cycles are
executed accurately.
Enter tool-length offsets and tool diameter values on the numbered
lines of the Tool Table. The numbered lines on the Tool Table identify
the tool number (T-Code) that activates those values.
You can program a tool activation as a separate block or include it
within the block for most moves and cycles. Tool activation's
programmed, as separate blocks are easier to find in a Program
Listing.
The Tool Table can store information for up to a number of tools
specified by the machine builder.
On machines equipped with collet-type tool holders, it is impractical to
use the Tool Table to store tool-length offsets. You can set tool-length
offset at tool change. Tool Table diameters are still required for
compensated moves and when using cycles that have built-in
compensation. You can run all Jog features from the Tool Table.
Tool Table offsets activate when you program a T-Code.
