Overview
Most of the program steps described in this section can be performed 
as one-step milling functions from the DRO screen or be included as

the data is entered.  Much of the information in this chapter should be 
familiar after performing the demonstration program in Chapter 7.

Repeatable tool length offsets
Programming a tool
When a program is using the Tool Length function, there are two 
requirements that must be followed to ensure that the tip of all 
additional tools is actually where MILLPWR
G2 has calculated it to be.
All tools used must have a fixed, repeatable length.
The surface that the tool touches off on must be a repeatable 
surface and used for all tools added to the program.
This also applies to all tools...
