In continuous-path operation (G64), block transitions are covered without feedrate reduction,
i.e. the path is rounded at points of discontinuity in the contour to an extent that depends on
the traversing rate.
As a result of function G62 (continuous-path operation with feedrate reduction), the tool path
feedrate is reduced to the rate entered in NC MD 3, provided the selected feedrate was
greater.
The rounding radius is thus reduced at discontinuous block transitions.

Exact positioning
Practical application:
When the traversing rate must not become zero on a block change (exact positioning) but the
feedrate in continuous-path operation is too high.
Note:
With SW 5 and higher, separate values can be set for G620/G00, G62/G01 and G62/G36.
See MD 146*, MD 148*, MD 150*.
