Within this context, workflow is typically character- ized by the CAD-CAM-CNC process chain. From the CAD system right through to the control system, Siemens can offer an integrated solution for these requirements in the form of its SINU- MERIK products.

Page 10: Linear Axes, Rotary Axes And Kinematics
Using three linear axes and two rotary axes, theoretically any point in space can be approached with any tool orientation. This is the basis of 5-axis machining. © Siemens AG All rights reserved. SINUMERIK, Manual, 5-axis machining...
Page 11 In addition to programming based on the direction vector and rotary axis positions, other forms of angle programming are also common. These include, for example, Euler or RPY angles.

Thus, the machining result is no longer a free- form surface, but a polyhedron. The small planes of the polyhedron can be visibly mapped on the surface. This can result in undesirable remachining. © Siemens AG All rights reserved. SINUMERIK, Manual, 5-axis machining...

CAM systems define the position of the TCP differently depending on the tool shape. For Siemens controls, it is assumed that the TCP is at the tool tip. If the CAM system specifies a different TCP position then this difference must be taken into account when specifying the tool length.
