1.4.5 Linear axis and rotary axis
NO.1006 Bit0(ROTx) can set each axis to linear axis or rotary axis. NO. 1006 Bit 1 (ROSx) can
be used to select the rotary type for each axis.
Absolute coordinate value is displayed circularly with the movement per rev set by NO.1260
when the cycle function is executed, which can prevent the rotary axis from overflowing. The cycle
function is valid when NO.1008 Bit 0(ROAx) is set to 1.
For absolute value command, the coordinate values is the corresponding angle cycle value of
per rev set by NO. 1260 after the machine moves. When NO.1008 Bit 1(RABx) is set to 0, the
machine rotates according to the shortest distance(to the target point). For incremental command, the
machine moves according to the angle defined by the command.
1.5 Structure of an NC Program
User needs to compile part programs (called program) according to command formats of CNC
system. CNC system executes programs to control the machine tool movement, the spindle
starting/stopping, the cooling and the lubricant ON/OFF to complete the machine of workpiece.
Program example:
Fig. 1-9
O0001 ; (Program name)
N0005 G0 X100 Z50; (Rapidly positioning to A point)
N0010 M12; (Clamping workpiece)
N0015 T0101; (Changing No.1 tool and executing its offset)
N0020 M3 S600; (Starting the spindle with 600 r/min)
N0025 M8 (Cooling ON)
N0030 G1 X50 Z0 F600; (Approaching B point with 600mm/min)
