Position Readout
The position readout is used to determine the current
position of the spindle/cutting tool. It can be used like a
digital readout on a manual milling machine.

Homing The Mill
Homing means to move the spindle or cross slide
to a fixed known position on the machine.
Homing commands perform two functions:
1. To check against a specified coordinate for calibration
loss.
2. To provide for quick machine set up when the part
location does not vary.

CNC Milling Machine Axis
The Milling machine
moves along three Axis X, Y and Z. When
programmed the mill
moves to coordinates
along the three axis. The
origin is the point at
which the three axis meet.
The graphic shows the
orientation of these axis.

Tool Library
Setting up the tool library properly is a critical step. Once the tool
library is setup, however, it does not need to be changed unless a
new tool is loaded into a an existing tool holder. During setup the
tool is defined by its geometry, size, number of teeth and relative
length (Height Offset).
Tool Library
Some of the information in the tool library is simply
used when verifying programs. For instance, the NC
program only directs the center of the tool so the
verify program needs to know the diameter of each
tool to show how much material is removed. The tool
offsets and tool numbers, however, are very
important when running programs with multiple tools.
Each tool must be defined with a Tool Height Offset.
Tool Setup
The first step in setting up a tool library is to home the
machine. The homing process send the mill to a known
position along all three axis. The machine can be
homed by:
•Selecting Setup in the menu bar and then “Set/Check Home”
•Holding the “Control” key and typing “H”
•Right Clicking on the Jog Control Panel and selecting
“Set/Check Home”

Continue setting up as many tools as necessary in the library. Any time that a
tool is removed from the tool holder (not the spindle) the height offset must be
reset. Now lets take a closer look at some more options in the tool library.

Editing Programs
The following techniques are helpful when editing
programs:
Find - In the Edit Menu, Find can be used to search for
specific text. This might be used to find a moves made
to negative Z depths.
Editing Programs
The following techniques are helpful when editing
programs:
Replace - In the Edit
Menu - Used to find
specific text and replace
it with a correction.
Helpful in changing feed
rates that have been
placed all throughout the
program.
Editing Programs
The following techniques are helpful when editing
programs:
Goto - Found in the Edit menu - Sends the edit cursor
to a specified program line. This is helpful when it is
necessary to make a change on a line that has been
identified by the software as having an error.
