System overview (840Di)
An overview of the system components required for clearance control in conjunction with
SINUMERIK 840Di is provided in the following diagram.

1D/ 3D machining
Clearance control can be used for 1D and 3D machining with up to five interpolatory axes.
• 1D machining
In the case of 1D machining, clearance control is only applied to one axis, e.g. axis Z, as
shown in the example machine configuration in the system overview for each SINUMERIK
system (see "System components for clearance control with SINUMERIK 840D" and
"System components for clearance control with SINUMERIK 840Di" above). Clearance
control acts only in the direction of the Z axis.
• 3D machining
3 linear axes are used to position the tool. One or two rotary axes are used for the
orientation of the tool vector (5-axis machining). Up to 3 linear axes are controlled by the
clearance control. The direction of the compensation movement can be defined either in
the direction:
