Chapter 1 Programming Fundamentals
The automatic machining of CNC machine is the course of edited part programs automatically
running. The programming is defined that the drawing and the technology of machining workpiece
are described with CNC language and are edited to the part programs.
Here describes the definition of command and the programming mode of CNC part programs.
Please read carefully these contents before programming.
1.1 Coordinate Axis and its Direction
This system has defined the controlled axis and its motion according to GB/T 19660—2005/ISO
841 ： 2001
Industrial Automation System and Integration-Numerical Control of
Machines-Coordinate System and Motion Nomenclature.
The two coordinate axes are
named with X and Z, which are perpendicular each other to form X—Z plane rectangular
coordinate system as Fig. 1.
Fig. 1 X—Z plane rectangular coordinate system
X
：
It is defined to be perpendicular with the rotary centerline of spindle. X positive direction is the
one that the tool leaves from the rotary center of spindle.
Z
：
It is defined to be coincident with the rotary centerline of spindle and Z positive direction is the
one that the tool leaves from the headstock.
1.2 Machine Zero
The reference point is a fixed point on the machine. Generally, it is set at the position of X, Z max.
stroke, the machine zero signal and the stopper are installed here. If the system is not equipped
with the machine zero signal and the stopper, please do not use this function, or set P12 Bit7 to
0.
1.3 Programming Coordinate
The absolute coordinates (X, Z word), the incremental coordinates(relative coordinates) (U, W
word) or the compound coordinates (X/W, U/Z word) can be applied to the programming in the
