Section 1 - Programming Concepts
Introduction
This section contains programming concepts for the beginning
programmer. It contains terminology and concepts that should be
mastered before writing programs.
Programs
A program is a precise sequence of machine instructions. Each program
consists of blocks of information that instruct the movements and
sequence of events to machine a workpiece. These blocks include all
necessary events, including activating the spindle, coolant, tool selection,
and all axis movement required to cut the workpiece in a safe and
productive manner.
Every program is given a unique name for identification. Programs are
stored in the CNC’s memory and accessed from the CNC’s Program
Directory. You can create, delete, undelete, copy, and rename programs
in the CNC’s Program Directory.

Axis Descriptions
Z Axis
Refer to Figure 1-1. Motion along the Z-axis is linear. Positive Z motion
is toward the tailstock and negative Z motion is toward the headstock.
C Axis
Refer to Figure 1-1. The C-axis is reserved for rotary spindle motion,
which can be clockwise or counterclockwise.
The builder determines C axis capability.

X Axis
Refer to Figure 1-2. In relation to the tool, positive X motion is away from
the centerline of the part. Negative X motion is toward the centerline of
the part. If the tool passes the centerline, the value of X will be negative.
Positive X direction varies, depending on whether a Front or Rear Tool
Post is used.

Part Zero Definition
NOTE: In general, all drawings in this manual assume a front tool post
configuration. The builder determines the tool post
configuration.
Refer to Figure 1-3. The intersection of the zero X and zero Z point is
the reference point that defines part zero. In X, this is usually at the part
centerline; in Z, it is at the front face of the part.

The reference point for moves in Absolute Mode is Part Zero; in
Incremental Mode, it is the current position.

Example (using front tooling and Incremental Mode): In X, to
travel 2 inches toward the part centerline (negative direction), program
X-4. (In Incremental Mode, an X-4 command moves the tool 2 inches
per side.) In Z, to travel 6 inches towards the chuck (negative
direction), program Z-6.
Polar Coordinates
Refer to Figure 1-4. If it is inconvenient to use X and Z coordinates, you
can use the Polar Coordinate System. Polar Coordinates can only define
points that lie on a single plane. Polar coordinates use the distance from
the origin and an angle to locate points.

Absolute Positioning
Refer to Figure 1-5. When the CNC is in the Absolute Mode, all positions
are measured from Absolute Zero. The Absolute Zero Reference, also
called Part Zero, is not a fixed position on the machine; you select the
point.
ABSOLUTE
Figure 1-5, Absolute Positioning
You can set the Absolute Zero (X0, Z0) anywhere. Absolute Zero
Reference is frequently at a position that makes it easy to use blueprint
dimensions.
NOTE: In Absolute Mode, a move to X0, Z0 will move the machine to
Absolute Zero.

Incremental Positioning
Refer to Figure 1-6. Incremental positions are measured from the
machine’s current position. This is convenient for performing an
operation at regularly spaced intervals.
INCREMEN
Figure 1-6, Incremental Positioning
NOTE: If an Incremental command to X0, Z0 is programmed, the CNC
remains at the current position.
Diameter or Radius Programming
NOTE: All program examples in this manual use Diameter
Programming.
Refer to Figure 1-7, Diameter and Radius Programming. X Dimensions
can be given in Diameter or Radius Mode:
Diameter X absolute dimensions are given as diameter values. X
incremental dimensions are given as the diametric
distance from the current diameter. X arc centers (I) are
always given as actual distances.
Radius X absolute dimensions are given as radius values. X
incremental dimensions are given as distance from the
current position.
Since X0 is usually the centerline of the workpiece, diameter
programming can simplify the programming of the workpiece.

The default, set by the machine builder, is usually Diameter.
NOTE: In canned cycles (with the exception of area clearance), all X
values are given as radial, regardless of whether diameter or
radius programming is used.
Developing Part Programs
The most important part of writing a CNC program is the planning. The
following guidelines are provided to help a first-time programmer organize
the process.
First, decide how to hold the workpiece in the machine and where to set
Part Zero. Part Zero is best located on the front face of the workpiece
along the Z-axis and at the centerline of the workpiece in the X-axis. Try
to select a Part Zero that facilitates the direct application of part print
dimensions.
Develop a program using a procedure similar to the one that follows:
1. To enter the Program Directory from the Manual screen, press
Program (F2).
2. Create a program name for the part by pressing Create (F2).
3. Enter the program name in the entry field for New Program.
Refer to “Section 10 - Program Management” for additional in-depth
information.
4. Enter the Program Editor (press Edit (F8)) to open the new program
and start writing blocks as described in steps 6 – 9 below.
Refer to “Section 6 - Program Editor” for additional in-depth
information.
5. The first block of any program is usually a safe start position and tool
change position (a position away from the workpiece to which the
axes can return for safe tool-changing). The first block is also
normally used to state the units of measurement (Inch/MM), the mode
of operation (Absolute), the move type (Rapid), and to cancel all
auxiliary functions (Tool Offsets, Spindle, Coolant).
Typical first block: G70 G90 G0 X0 Z0 T0 M5
