Model G0894 (Mfd. Since 05/19)

The following is a list of common definitions, terms and phrases used throughout this manual as they relate

to this CNC router and woodworking in general. Become familiar with these terms for assembling, adjusting

or operating this machine. Your safety is VERY important to us at Grizzly!

Glossary Of Terms

Axis:

Direction of movement. On a three-axis mill-

ing machine, axes are typically X (left-right),

Y (front-back) & Z (up-down). Axis directions

are described as positive or negative. On this

machine, negative movement is defined as

movement towards the front (Y), left (X), and

bottom (Z) of the working envelope.

Ball End (Ball Nose):

A cutting tool that has a

rounded cutting arc, where the arc diameter

is equal to the cutting diameter.

Ball Screw:

Drive system component. The ball

screw is rotated by the stepper motor and

provides the means for moving the gantry

and spindle along the axes.

Bed:

The bed of the CNC consists of a welded

steel frame, an extruded aluminum table top,

and a tongue-and-groove table top with inte-

grated T-slots.

CAD:

Computer aided design. CAD software is

used to create a digital model of a project.

CAM:

Computer aided manufacturing. CAM soft-

ware converts CAD models into a toolpath

defined by G-code that CNC machines can

interpret.

Chip Load:

Chip load is the measure of the

thickness of chips a tool will cut. Chip load

is equal to: Feed Rate ÷ (Spindle Speed X

Number of Flutes).

CNC:

Computer numerical control. Manufacturing

controlled by a computer via coded instructions.

Climb Cut:

Cut that occurs when the rotation of

the cutter moves in same direction as the

workpiece.

Collet:

Metal collar that holds the cut-

ting tool in place within a spindle nut.

Conventional Cut:

Cut that occurs when the

rotation of the cutter moves in opposite direc-

tion as the workpiece.

Compression Bit:

A cutting tool with a combina-

tion of up and down shear cutting edges.

Typically used for cutting laminate material to

prevent tear-out on both sides of the sheet.

Tool Deflection:

Tool deflection occurs when the

spindle speed and feed rate exert sufficient

force to deflect the cutting tool. Deflection

leads to excessive wear and chatter, which

can shorten tool life and leave unwanted

tooling marks on the material.

Down-Cut Bit:

A cutting tool with edges that

carve downward on the face of the tool-

path. Reduces the potential for tear-out, but

requires a slower feed rate.

Dust Shoe:

An accessory that channels dust and

debris directly from the cutting tool through

an attached dust collection system.

End Mill:

A cutting tool with a straight end, typi-

cally with spiral flute(s). It creates a channel

with a flat bottom perpendicular to the sides.

Feed Rate:

The speed at which the cutting tool

moves along a workpiece.

Flute Length:

The length of the cutting portion on

a router bit or cutting tool.

Flutes:

The cutting edges or inserts of a router bit

or cutting tool.

Finish Cut:

A 3D toolpath that reduces or elimi-

nates the irregular contours left by a rough

cut.
