Local coordinate system
: Set local coordinate system of workpiece coordinate system in order
to programme easily when programming in workpiece coordinate system.
Absolute Programming:
coordinates data of programming mode based on established absolute
coordinate system.Absolute coordinate value is corresponding to homing point of coordinate system.
It is settlements by “G90 X_Y_Z_A_”.
Relative Programming
(increment programming)
：
It is distance and direction of operation end
point ,compared with starting point.It is settlements by “G90”.
Mode Instruction
：
The instruction which can remain the function in the program.It works both
in this program and program in the future.
In the same operation, there may be several mode instruction, such as M03(spindle
clockwise),M04(spindle counter clockwise),M05(spindle stop).They are all mode used to control
spindle.The mode of same kind are categorized into one mode group.At any time it must be one of
them,and there is only one of them.The original chosen mode is called mode origin.In the above
mode group,M05 is such a mode origin .
Suspending Mode
(destroying mode): It is instruction which can turn mode instruction into mode
origin or destroy the mode.Such as M20(program ending instruction),meaning the end of operation
and returning to original status.
Non-Mode instruction
：
It is the instruction which has no function to store,and only works in the
segment of program.
2.1.1 Tool Movement Along Workpiece Parts Figure Interpolation
The tool moves along straight lines and arcs constituting the workpiece pats figure(See
Fig2.1.1)
The function of moving the tool along straight lines and arcs is called the interpolation.
a)Tool movement along a straight line
Fig2.1.1 Tool Movement along a line
b)Tool movement along an arc
