HEIDENHAIN iTNC 530 HSCI - Conditions and Constraints

July 2013 6.5 Tilting and swivel axes 765
Conditions and
constraints
Conditions:
 The display position in the status window is referenced to the tilted
coordinate system.
 In the combination of coordinate transformation cycles the sequence of
activation must agree with the sequence of deactivation.
 The tool radius compensation in the working plane and the tool length
compensation parallel to the tool axis is active.
 For machining with tilting tables, the coordinate system remains parallel to
the machine coordinate system.
 If MP7500 bit 1=1 (spatial angle), Module 9045 shows all axes that will be
tilted.
 If MP7500 bit 1=0 (axis angle), Module 9045 shows all axes that are actually
tilted.
Constraints:
 PLC positioning movements are always parallel to an axis of the machine
coordinate system (Cycle 19 has no influence).
 A datum shift via PLC also works with the "tilted working plane" function.
 The axis designations for the tilting axes are limited to A, B and C. Each
designation can be used only once.
 With an active Cycle 19 "Tilted working plane," it is not possible to position
with M91 or M92.
 Please note that the "Tilt working plane" function remains active even after
the cancelation of a block scan, the end of an NC program or a reset, until it
is explicitly deactivated. In these cases, the tilted plane should be
specifically deactivated by means of a suitable Cancel macro in order to
avoid machine movements that the user does not expect.
If the position of the working plane is entered, only the following tilting axes
(with tool axis Z) are permissible:
 Double swivel head 45°: Axis sequence A fixed; B or C variable; A fixed;
B or C variable
 Rectangular double swivel head: Axis sequence A or B variable; C variable
 Rotary or tilting table: Axis sequence C variable; A or B variable
 Swivel head and rotary table: Axis sequence A or B variable; C variable
 Tilting table 45°: Axis sequence C variable; A fixed; B variable; A fixed
 Rectangular double swivel head: Axis sequence A variable; B variable
 Universal swivel head: Axis sequence A fixed; B –90°; A variable; B +90°; A
fixed; C variable
 Swivel head and rotary table: axis sequence B variable, A variable
 Swivel head and rotary table: Axis sequence C fixed, A fixed, B fixed –90°,
A variable, B fixed +90°, A fixed, C fixed, C variable
