Creating a ShopMill program

7.4 Creating a ShopMill program
Incremental dimensions
In the case of production drawings in which dimensions refer to some other point on the
workpiece rather than the zero point, it is possible to enter an incremental dimension.
When incremental dimensions are entered, each item of position data refers to a point
programmed beforehand.
Example
Y
20
15
20
The position data for points P1 to P3 in incremental dimensions are:
P1: X20 Y35 ;(referred to the zero point)
P2: X30 Y20 ;(referred to P1)
P3: X20 Y-35 ;(referred to P2)
7.4 Creating a ShopMill program
Create a separate program for each new workpiece that you would like to produce. The
program contains the individual machining steps that must be performed to produce the
workpiece.
If you create a new program, a program header and program end are automatically
generated.
