7.1 Demonstration Program
Overview
The following steps and key stroke sequences will guide you through
creating a demonstration program based upon information from the
part drawing shown.
All dimensions are in inches.
This will help introduce you to MILLPWR G2 and familiarize you with
how it operates.
Selecting Datum
Although there is no clear "zero point" identified on this print, use the
center of the bolt hole pattern as datum. There are advantages to
using this location:
 It is the center of the bolt hole pattern
 It is the center of the large arc, making it easy to calculate the arc's
start and end points.
 The pocket is dimensioned from this point, and nearly all of the
dimensions on the print originate from this point.
This print could also be programmed using another point such as the
upper left corner, for example as datum.
The datum will be ready to set just before running a program.
