Friends, we have to know which type of drilling is done more in depth. for deep drilling is considered as DEPTH/ DIA => 5
The benefits of peck drilling reduce cycle time. In G73 peck drilling after each drill, tool retract only 1 mm.This drilling cycle is used mostly drill soft materials like; Aluminium
O4231
N10 M06 T06 ;
N20 G90 G80 G17 G00 G54 X0 Y0 ;
N30 G43 Z100 H11 ;
N40 M03 S1500 ;
N50 M08 ;
N60 G99 G73 Z-55 R5 Q20 F300 ;
N70 G98 G80 G00 Z100 ;
N80 M05 M09 M30 ;
More examples..........!!!!
