Basic information
1.5.2 Kinematics of 5-axis machining centers
A 5-axis machine can control tool motion in five axes. These are the three linear axes (with which
you will already be familiar) and two additional rotary axes. There are different kinematic
solutions for the two rotary axes. We will present the most common of these schematically. With
SINUMERIK controls, even special kinematics can be controlled on the basis of the integrated,
kinematic transformation feature. Special cases such as hexapods, etc. will not be explored in
further detail here.

*: If the axis of rotation is not perpendicular to a linear axis, then this is known as a "nutated" axis.
