In the command examples, the lde symbol (~) stands for a real value. If L~ is wrien in an example,
the ~ is oen referred to as the L number. Similarly the ~ in H~ may be called the H number, and so
on for any other leer. As described in detail elsewhere, a real value may be one of the following:
• An explicit number. For example: 4.4
• An expression. For example: [2+2.4]
• A parameter value, For example: #88
• A unary funcon value. For example: acos[0]
Many commands require axis words (X~,Y~,Z~, or A~) as an argument. Unless explicitly stated
otherwise, the following assumpons can be made:
• Axis words specify a desnaon point
• Axis words relate to the currently acve coordinate system, unless explicitly described as
being in the absolute coordinate system
• Where axis words are oponal, any omied axes retain their current value
Any items in the command examples not explicitly described as oponal are required.
7.3.1 Rapid Linear Motion – G00
For rapid linear moon, program: G00 X~ Y~ Z~ A~
Word Definition
X~ X-axis coordinate
Y~ Y-axis coordinate
Z~ Z-axis coordinate
A~ A-axis coordinate
This produces coordinated linear moon to the desnaon point at the current traverse rate (or
slower if the mill does not go that fast). It is expected that cung won’t take place when a G00
command is execung. It is an error if all axis words are omied. The axis words are oponal, except
that at least one must be used. The G00 is oponal if the current moon mode is G00.
If cuer radius compensaon is acve, the moon diers from the above; see Cuer Compensaon
later in this chapter. If G53 is programmed on the same line, the moon also diers; see Absolute
Coordinates later in this chapter. Depending on where the tool is located, there are two basic rules
to follow: If the Z value represents a cung move in the posive direcon (i.e. out of a hole), the
X axis should be moved last. If the Z value represents a move in the negave direcon, the X-axis
should be executed rst. It is an error if:
• All axis words are omied
• G10, G28, G30 or G92 appear in the same block
