3. INTERPOLATION FUNCTIONS
NC FUNCTION
45
Helical interpolation B moves the tool in a helical manner. This
interpolation can be executed by specifying the circular interpolation
command together with up to four additional axes in simple
high–precision contour control mode.
Basically, the command can be specified by adding two movement axes
to a standard helical interpolation command (see Section 3.5). Address
F should be followed by a tangential velocity, which has been determined
by also taking movement along the linear axes into consideration.

The feedrate equals the tangential velocity determined
by also taking movement along the linear axes into
consideration.
