Sample File 1 (HPGL 3D code)
The following is a 5" square.
Rapid level .5 inches above material, feed down 60 ipm, cut feed
200 ipm, depth
.25 inches. This is for a single head system with manual tool change.

| PD0,0,-10 |
Position X=0.0, Y=0.0, and

The PD command should be called before the Z axis is lows the tool into
the Material or at the start of a new contour.
- The Auxiliary output for the selected tool is turned on. (This output
can be wired to operate a tool misting or cooling unit.)
- The Motion will change from Slew mode (high speed rapid) to Machine
mode (Cutting Mode)
- If this is the first PD called in the program the spindle output will
come on for the current selected tool. |

Sample File 2 (HPGL 2D code)
This is a simple HPGL 2D file. The
user would set all speeds, depths and the tool lift at the keypad.
Notice that there is no "G00 C" command.

Moves the Z axis to Tool Lift
position that is set at keypad. The tool lift is the distance
above the material in reference to Z=0 or the surface of the
material. |
| PA0,0 |

| PD |
Moves the Z axis to the depth
set at the keypad. The depth is the distance into the material
in reference to Z=0 or the surface of the material.
The Z axis is lowered the tool into the Material at the start of a new
contour when the PD command is called
- The Auxiliary output for the selected tool is turned on. (This output
can be wired to operate a tool misting or cooling unit.)
- The Motion will change from Slew mode (high speed rapid) to Machine

End of Job. The spindle is
turned off at this time. |
The following is the same file as above with
some added 2D commands. All of the speeds and depths are set the
same as Sample one. The ZD, ZU, and SF commands can be sent at
any time in the file. The PD and PU commands that follow will use
the new settings of these commands.

Sample File 3 (ATC Tool 3)
The following is a program to cut 2 squares with
tool 4 and 2 circles with tool 1. The first circle is counter clockwise
and the second circle is clockwise. The Squares are 5 inches and
the Circle are 4 inches in diameter. The file is in 3d mode and
all speeds and feeds are set in the file.
