Tool Orientation (Oric, Orid, Osof, Osc, Oss, Osse, Oris, Osd, Ost) - Siemens Sinumerik 840D sl Programming Manual

7.6 Tool orientation (ORIC, ORID, OSOF, OSC, OSS, OSSE, ORIS, OSD,
OST)
Function
The term tool orientation describes the geometric alignment of the tool in space. The tool
orientation on a 5-axis machine tool can be set by means of program commands.
Orientation rounding movements activated with OSD and OST are formed differently
depending on the type of interpolation for tool orientation.
If vector interpolation is active, the smoothed orientation characteristic is also interpolated
using vector interpolation. On the other hand, if rotary axis interpolation is active, the
orientation is smoothed directly using rotary axis movements.
Programming
Programming a orientation change:
A change in tool orientation can be programmed by:
• Direct programming of rotary axes A, B, C (rotary axis interpolation)
• Euler or RPY angle
• Direction vector (vector interpolation by specifying A3 or B3 or C3)
• LEAD/TILT (face milling)
The reference coordinate system is either the machine coordinate system (ORIMKS) or the
current workpiece coordinate system (ORIWKS).
