integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage

from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to the State

of California to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

Work in a well ventilated area, and work with approved safety equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles.

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).

Climb Cut: Cut that occurs when the rotation of

the cutter moves in same direction as the

workpiece.

CNC: Computer numerical control. Manufacturing

controlled by a computer via coded instructions.

Collet: Metal collar that holds the cutting tool in

place within a spindle nut.

Compression Bit: A cutting tool with a combi-

nation of up and down shear cutting edges.

Typically used for cutting laminate material to

prevent tear-out on both sides of the sheet.

Conventional Cut: Cut that occurs when the

rotation of the cutter moves in opposite direc-

tion as the workpiece.

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.

Finish Cut: A 3D toolpath that reduces or elimi-

nates the irregular contours left by a rough

cut.

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.

Form Bit: A bit that carves a standard profile such

as a roundover, ogee, or similar contour.

Gantry: The structure that straddles the bed and

carries the spindle. It moves the full length of

the bed along the Y-axis.

G-Code: A machine language that uses axis

points and commands, which the machine

uses to move and perform functions.
