10.2.1 About the Examples Used
Many commands require axis words (X~, Y~ ,Z~, or A~) as an
argument. Unless explicitly stated otherwise, you can make
the following assumptions:
l Axis words specify a destination point
l Axis words relate to the currently active coordinate
system, unless explicitly described as being in the
absolute coordinate system
l Where axis words are optional, any omitted axes retain
their current value
Any items in the command examples not explicitly described
as optional are required.
10.2.2 Rapid Linear Motion (G00)
For rapid linear motion, program: G00 X~ Y~ Z~ A~
l X~ is the X-axis coordinate
l Y~ is the Y-axis coordinate
l Z~ is the Z-axis coordinate
l A~ is the A-axis coordinate
This produces coordinated linear motion to the destination
point at the current traverse rate (or slower, if the machine
won't go that fast). It's expected that cutting won’t take place
when a G00 command is executing. The G00 is optional if the
current motion mode is G00.
Depending on where the tool is located, follow these two basic
rules:
1. If the Z value represents a cutting move in the positive
direction (like out of a hole), the X-axis should be moved
last.
