6.12. G37. TANGENTIAL APPROACH AT THE START OF MACHINING
The preparatory function G37 can be used to link two paths tangentially without having
to calculate the intersection points.
Function G37 is not modal, i.e., it has to be programmed every time two paths are to be
linked tangentially. There paths may be straight-straight or straight-arc. The radius, R4.3
in mm or R3.4 in inches, of the entry arc must be programmed following G37.
The value of the radius must be positive.
That programming has to be carried out in the block which incorporates the movement
whose path is to be altered. The movement must be rectilinear (G00 or G01).
When G37 R4.3 is programmed in a block in which a circular movement (G02 or G03) is
incorporated, the CNC will display the error 41.
