Two M-codes can be used to cause a ____.

The X- and Y-axes of the Cartesian coordinate system divides the system into four separate regions called ____.

____ allows verification of the paths the tool will take by watching a simulated computer model cut the part on a display screen.

____-codes are used to turn on and off miscellaneous (auxiliary) functions.

The ____ is used for the machine's own reference purposes and helps it to keep track of how far each axis can move before it runs out of travel.

The coolant command ____ refers to the command for mist coolant.

The ____ flange was originally developed specifically for CNC use by Caterpillar Inc.

A ____ is a tool that is mounted to the turret and, when programmed, can approach the remaining bar material after a part has been cut off.

Using a combination of a T- and M-word command in a single block is performing a ____.

When a machine is programmed ____, all X coordinates are expressed as diameters.

____ coordinates require that positions be identified by defining both an angle and a distance (like a vector in mathematics).

The drawing type wherein the part shape is defined by a thin outline only, appearing as though the part's image is made of a framework of thin wires is called ____ drawing.

Once tool measurements have been determined, those tool offset measurements are stored in the machine's ____ offset page.

A G83 is for the ____ drilling cycle and fully retracts the tool from the hole between pecks.

The configuration of a modern ____ can be compared to a standard vertical knee-type mill.
