8.0 Program Mode Part 2: Program Events

Events are fully defined pieces of geometry. By programming events, you tell the

ProtoTRAK PMX CNC what geometry you want to end up with; it figures the tool path

for you from your answers to the prompts and the tool information you give it in the Set-

Up Mode.

8.1 POSN: Position Events

This event type positions the table and spindle at a specified position. The positioning is

always at rapid speed (modified by feedrate override) and in the most direct path possible

from the previous location. The most common use of the position event is to move the

tool around an obstacle such as a clamp. For this reason, Z and X - Y motion will not

occur simultaneously. First, the Z (head) will move to the higher of the Z rapid position

of the current and next event, then the X (table) and Y (saddle) will move to the

programmed position.

To program a Position event press the POSN soft key.

Prompts for the Position event:

X END is the X dimension to the position

Y END is the Y dimension to the position

Z Rapid is the Z dimension to the position

RPM is the spindle RPM for the event. INC SET will use the RPM of the previous event.

Tool # is the tool number you assign. SET will use the tool number of the previous

event.

Note: the blue ? is active during the Tool # prompt. Pressing the HELP hard key will

take you to a screen where you may view, edit or enter tool diameter and tool type.

NOTE - On all RPM line prompts for all events except tap, a blue “?” will be visible,

which when pressed will allow the user to run the spindle in reverse. A “REV” prompt

will show up in the event to the right of the RPM programmed.

8.2 DRILL Events

This event positions the table to the specified X and Y position, moves the spindle at

rapid to the Z RAPID location, feeds the tool to the Z END location, and rapids back to Z

RAPID for drill, and feeds back for bore.

Press the DRILL soft key.

Prompts for the drill event:

Drill=1, Bore=2: selects whether the hole is to be drilled or bored.

X: is the X dimension to the hole

Y: is the Y dimension to the hole

Z Rapid: is the Z dimension to transition from rapid to feed

Z End: is the bottom of the hole

# Pecks for Drill: the factory setting is for each peck to be successively smaller, taking

the largest cuts at the beginning and the smallest at the end. When the highlight is on this

prompt, you may change this setting by pressing the HELP key. This will take you to a
