HEIDENHAIN CNC Pilot 4290 - Manual (Page 280)

6 TURN PLUS 268
Peak-to-valley height
The peak-to-valley height is evaluated during finishing (see also ”
4.5.4
Auxiliary Commands of the Contour Description”).TURN PLUS
distinguishes:
■ Peak-to-valley height (Rt) – general peak-to-valley depth (profile depth)
■ Mean roughness index (Ra)
■ Average roughness value (Rz)
Additive correction
The CNC PILOT manages 16 tool-independent compensation values.
In the dialog box, you enter the number of the additive correction
value. The correction value is defined during the machining of the
workpiece.
Exclusion from machining
The effect of the attribute depends on the type of machining:
■ Roughing: The attribute is evaluated with the first/last element of
an inside/outside contour. Form elements are not machined.
■ Finishing: Marked elements are not finished.
■ Predrilling: Attribute is ignored.
■ Recessing: Marked recesses are not machined.
■ Thread machining: Marked thread elements are not finished and
threads are not cut.
■ Centering: Marked holes (form elements) are not drilled.
■ Drilling: Marked holes (for C/Y machining) are not machined.
■ Milling: Marked milling contours (for C/Y machining) are not
machined
6.9.4 Precision stop
Tagged contour elements are machined with the ”precision stop”
(see also ”
4.5.4 Auxiliary Commands of Contour Description”).
6.9.5 Separation Points
are used for shaft machining or machining with multiple setups.
After the element is selected, TURN PLUS opens the ”selection point”
dialog box.
Parameters
Position:
■ Delete: Deletes an existing separation point (a division of
the contour element remains, however)
■ 1. In target point: Separation point at the end of the element
■ 2. On element: Separation point lies on the element
X, Z: Position of the separation point
