Contour –Parallel Roughing Cycle G73 Or Profile Turning Cycle Or Copy Turning Cycle
This function will allow efficient execution in roughing when cast or forged parts are to be cut along finish shape.
Programming Format:-
G73 U___ W__ R__ ;
G73 p__ Q__ U__ W__ F__ S__ T__ ;
U = escape distance and direction in the X-axis direction ( radial value )
W = escape distance and direction in the Z-axis direction
R = times of divisions
* Other Addresses Are As With G71
Tool Nose Radius Compensation:-
When this cycle is commanded in the tool nose radius compensation mode, tool nose radius compensation is applied to the finishing shape sequence for this cycle and cycle is executed for this shape.
However, when this cycle is commanded in the tool nose radius compensation mode, the compensation is temporarily cancelled immediately before this cycle and started at the head block of the finishing shape sequence.
