G73 Pattern Repeating cycle (cnc programing)

G73 pattern repeating cycle


G73 पैटर्न repeating साइकिल  और G71 साइकिल से थोड़ा डिफरेंट है ये दोनो Cycle OD turning के लिए use होती है लेकिन दोनो का काम करनेका तरीका अलग है 

 G73  U  W  R

G73 P  Q  U  W  F

U- machining allowance on X axis

W- machining allowance on Z axis

R- number of rough cut


P- sequence number of the first block of       the program

Q- sequence number of the first block           of the program

U- finish allowance on X axis /diameter

W- finish allowance on Z axis /face

F - Feed


Example drowing

G73 pattern repeating cycle


The G73 pattern is slightly different from the repeating cycle and the G71 cycle. Both cycles are used for OD turning, but the working method is different.
