8.15 ENGRAVE Event

The Engrave Event allows you to machine numbers, letters and special characters as part

of a part program. See below for the letters and special characters that are available in

the Engrave Event.

When programming with the Engrave Event, the ProtoTRAK will construct a box to

contain the text you define. This box is oriented along the X axis like the text in this

sentence, and you may program up to 40 characters per event (although you will only be

able to see 20 characters on the prompts screen). To machine text in a direction other

than the X axis, simply use multiple Engrave Events and place the lower left corner of the

box wherever you would like. The numbers and letters you program will always have a

standard orientation (like the letters on this page) – you cannot program tilted or inverted

letters with the Engrave Event. The letters are of the font shown in the figure and all

capitals.

Prompts for the Engrave Event:

First, define the lower left corner of the box that will contain your text:

X BEGIN: The X coordinate of where you want your text to begin

Y BEGIN: The Y coordinate of where you want your text to begin

Z RAPID: The Z dimension where the Z rapid feed slows to Z program feed

Z END: The Z dimension to the bottom of your text.

HEIGHT: The height of your text. Each character varies in width; the set height of the

character will change the width in order to keep the overall size of the character

proportional.

TEXT: The text to be milled. When you get to this prompt, the Alpha keys will

automatically pop up to allow you to enter the text. Once you have finished entering text,

you must press End and then any of the SET keys to successfully enter your text into the

event. The alpha keys will appear automatically if the text field is blank. If you have

already entered text but wish to make a change, you will see a blue question mark appear

on the lower left corner of the screen when you scroll to this field, press the Help button

and the alpha keys will appear.

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

event.

Z FEEDRATE: is the Z feedrate from Z rapid to Z end in in/min from .1 to 800, or

mm/min from 5 to 20320.

XYZ FEEDRATE: The feedrate of XYZ along the path of the text

Tool #: is the tool number you assign
