Cutting quality

A term used on OMAX, and sometimes other controllers to indicate how the machine should cut a given surface
of the part. A quality of “1” being a very rough, high speed cut, and a quality of “5” being a very smooth, highly
precise operation. “Quality” was coined by OMAX Corporation, and is becoming the standard for describing sur-
face finish for abrasivejet machined parts.

Note, however, that different manufacturers of equipment use

“Quality” to mean different things.

For example what is “Quality of 1" by one manufacturers definition is not

the same as another’s “Quality of 1".

Degrees

When entering values for degrees:

•

Positive values move counterclockwise (that is, a line at 90º points straight up)

•

Negative values move clockwise (a line at -90º points straight down)

•

To enter values greater than 360, subtract 360 from the value until the value is less than 360. (Entering
an angle of 450º or 810º is the same as entering 90º). In other words, the number is divided by 360 and
the remainder is used as the angle.

Device driver

A “device driver” is software that tells your computer (and specifically Windows) how to communicate with a
device. If a scanner is connected to your computer, for example, there is a device driver than lets the computer
tell the scanner when to scan.

DOS

DOS is an older operating system using on IBM-compatible personal computers. DOS was introduced in the
early 80s and was the main operating system until the early 1990s when Windows 3.0 began to gain popularity.

Dot

A point at either end of an entity. When dots are turned on with the Config command in Layout, they appear white
on the screen.

Draft angle

The angle caused by Taper.

DWG File

A DWG file is a drawing file from AutoCAD. This is an unpublished format that is proprietary to AutoDesk, Inc.
Layout can read most DWG files by using the Import from other CAD function on the File menu. However,
because the file format is not publicly available, it is difficult to get good conversion results when using this file
type.

DXF File

DXF (Drawing eXchange Format) is a standard file format used to exchange drawings between CAD (Computer
Aided Drawing) programs. Most CAD and drawing programs support DXF files, including AutoCAD, CorelDRAW,
Mastercam and SmartCam.

Dynamic pierce

During a “dynamic pierce,” the nozzle and abrasive are turned on, and the nozzle begins to slowly move. As the
nozzle moves, the material is pierced. Contrast this with a wiggle pierce.

EDM

Acronym for “Electrical Discharge Machining”. A slow, but extremely precise method of machining using electri-
cal sparks to remove material in very small increments.

Endpoint

The point at either end of an entity. Each entity (line or arc) has two endpoints. When dots are turned on with the
Config command in Layout endpoints appear white on the screen.
