If, however, in the same example you require the entrance of the tool to the part to be machined
tangential to the path and describing a radius of 5 mm, you should program:
G90 G01 G37 R5 R5 X20 Z30
G03 X40 Z10 R20
As can be seen in the figure, the CNC modifies the path so that the tool starts to machine with a
tangential entry to the part.
You have to program Function G37 plus value R in the block which includes the path you want to
modify.
R5.5 should appear in all cases following G37, indicating the radius of the arc which the CNC enters
to obtain tangential entry to the part. This R value must always be positive.
Function G37 should only be programmed in the block which includes a straight-line movement (G00
or G01). If you program in a block which includes circular movement (G02 or G03), the CNC displays
the corresponding error.
