\par \pard\b0\fs16
\par \fs20 The G71 code commands a multiple repetitive cycle, sometimes referred to as a canned cycle. The G71 cycle is similar to the G72 cycle except that the cut is applied in the X axis.
\par Canned cycles are used within a CNC program to simplify programming, since only the dimensions describing the required component profile are required. The CNC control will then generate the roughing cuts needed to make this component profile, from within its own memory.
\par
\par
\par Prior to writing the command G71 within the program, the tool is positioned at the start point.
\par
\par Any F (Feed rate) or S (Spindle speed, rpm) commands between \f1 start block\f0 \f1 and end block\f0 numbers will only be effective on the finishing pass (G7\f1\'d8).
\par
\par \b A G71 command is written in the following format :
\par G71 U (1) R ;
\par G71 P ns Q nf U (2) W F ;
\par where,
\par U (1) is the depth of cut in the X axis (Radius value).
\par R is the escaping amount (Retract).
\par ns is the sequence number of the first block of the programmed finished shape.
\par nf is the sequence number of the last block of the programmed finished shape.
\par U (2) is the distance and direction of the finishing allowance in the X axis (Diameter value).
\par
\par W is the distance and direction of the finishing allowance in the Z axis.
\par F is the feedrate for Roughing.\b0
