DESCRIPTION
O1234 ;
N10- Tool change command, select cutter no. 6 .

N20- Program in the incremental coordinate system, work coordinate destination on milling machine, all dimension in “mm”, select xy plane, cancelled canned cycle if apply, tool height offset compensation negative ;

N30 – Spindle on clockwise speed 1200 r.p.m .

N40Rapid traverse where at position  X0 & Z0 .

N50- Rapid traverse where tool moves at the position Z10 , coolant is on .

N60- linear interpolation command where Z is 0 . (tool touch to workpiece ) , feed rate per revolution  is 0.2

N70- linear interpolation command where tool take position 15.75 in X axis , tool radius compensation left.

N80- Circular interpolation counterclockwise where I = -15.75 & depth of cut in Z axis is -4 .( first cut imaginary point P0 to P1)
I= An incremental distance and direction from the start point of the arc to the arc centre along the X axis.

N90- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( Second cut from point P1 to P2)
N100- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( Third cut from point P2 to P3)
N110- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( Fourth cut from point P3 to P4)
N120- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( Fifth cut from point P4 to P5)
N130- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( Sixth cut from point P5 to P6)
N140- Circular interpolation counter clockwise where I = -15.75 & depth of cut in Z axis is -4 . ( The seventh cut from point P6 to P7)

N150- linear interpolation command where tool return at starting position X =0 , tool nose compensation off.

N160- Rapid traverse where tool moves at the position Z50 .

N170- Coolant off , spindle off , main program end .
