CNC PROGRAMMING FOR STEP TURNING OPERATION WITH CHAMFERING
For learning CNC program we have to knowledge about G-Code and M-code .So friends in this programming specially focus on chamfering . Chamfering always given in degree . lets see following fig. there is some hidden dimension need to calculate .This operation perform only two steps . For calculating geometrical co-ordinate and chamfering CLICK HERE

CUTTING DESCRIPTION ( N070 to  N170 ) :
N070Tool travel X32 and Y 0 rapidly ; it means it means near to working position .
N080Tool at X 30 and feed is 0.12 ; it means  touch to the job at x .
N090- Tool cutting in x direction from X 30 to X0 .
N100- Tool return back to X30. (position 1)
N120Tool travel from Z 0.0 to Z -25.0 linerly ( position 2 to 3 )
N130 Tool   travel X47 AND Z-31 (position 3 to 4)
N140Tool travel  X 53 linearly ( position 4 to 5 )
N150-Tool travel X 60 and Z-37 (position 5 to 6)
N160Tool travel  Z-67 linearly ( position 6 to 7)
N170- Tool travel X78 and Z-73 (position 7 to 8)
