1. Reapproach contour, triggered by operator
REPOS allows the tool to be returned to the interrupt position by
means of the direction keys.
2. Programmed contour reapproach
A selection of approach strategies are available in the form of
program commands: Approach point of interruption, approach
start of block, approach end of block, approach a point on the
path between start of block and interruption.
The axis feedrate is adjusted as a function of the speed of the
master spindle in the channel (programmed with G95).
This function is used to tap holes without the use of a compensating
chuck. The spindle is controlled as an interpolative rotary axis and
drill axis, with the result that threads are tapped precisely to the final
drilling depth, for example, in blind tapped holes (precondition:
Spindle axis mode).
Rotary axes cause the tool or workpiece to rotate to a specified
angle position.
The range of motion of a rotary axis can be set to a modulo value
(in machine data) or defined as continuous in both directions,
depending on the application. Continuously turning rotary axes are
used, for example, for eccentric machining, grinding and winding.
Component of a --> frame which defines a rotation of the coordinate
system through a specific angle.
Rounding axes cause the workpiece or tool to rotate to an angle
position described on a graduated grid. When the grid position has
been reached, the axis is "in position".
