Chapter 2 Programming
CNC milling System is highly effective automation equipment according to programmed
program to process workpiece. Programming is using the CNC system control language according
to the requirement and drawing of the workpiece to describe the processing trajectory and the
assistant action. Ideal system not only could promise process qualified workpiece, but also make the
functions of milling reasonable application and fully use, so it is very important to programming,
this chapter will introduce many kinds of instructions and usage of CNC program, please read
carefully.
2.1 Basic Concepts of Programming
Item SZGH-CNC1000MDb
No. of Basic Controllable Axes 3 (X, Y, Z)
Expansion of controlled axis(total) Up to 5(X, Y, Z, A,B/C)
Table 2-1-1
Program Segment:
a complete command line consisted of instruction and data .
Program: is a congregation of program segment by machining logic structure in order to
complete the machining of workpiece.
Machine Coordinate System:
The establishment of coordinate is based on machine’s zero
point.The milling machine coordinate axis and its direction should follow to "ISO841" standard.
The method as follow: Through right hand rule we can make the program coordinate, The Z axis
is parallel as spindle, The X axis is horizontal, The Y axis is determined by right hand rule. The A,
B, C are rotated axis or assistant axis which parallel as X,Y,Z axis. Furthermore, The coordinate
axis direction is the increasing workpiece dimension direction.
When without set work coordinate, take machine coordinate as work coordinate.
Working Coordinate System : Work piece processing uses the coordinate system is called as
the work piece coordinate system, it is set by CNC. The work piece coordinate system could change
to move its zero point.
Set the workpiece coordinates:
1.Use G54 ~ G59: Use coordinate parameters to set 6 workpiece coordinate system.
2.G52: Set a value behind G52 to set the workpiece coordinate system in program.
With absolute value instruction ,it must use the above method to establish the work piece
coordinate system.
