Due to the manufacturing process, machine axes deviate from their ideal geometrical shape and are never exactly perpendicular to each other. The existing geometrical deviations lead to translational and rotational deviations which have the effect that the actual position deviates from the target position.

• AfM Technology GmbH acquires the existing, individual geometry deviations of all axes with special measuring methods.
• From the individual errors, AfM Technology GmbH can generate a machine-specific error map for the CNC and save it in the control.

By knowing the single geometry deviations from the error map, the SINUMERIK Run MyCC /VCS option is able to calculate the total error at the tool center point (TCP) during runtime at every individual position. As soon as this error has been calculated, the CNC can change the coordinates of the target position so that the calculated deviations are taken into account and the tool center point thus reaches the setpoint specified in the CNC program in the best possible way. Significant increases in the accuracy of the machine and machined products are the result.
