6.2.2.3 IKA data
IKA stands for interpolation and compensation with tables. This function can
be used on the SINUMERIK 840C in relation to machines and/or workpieces.
1. IKA data defining a machine
The IKA function is used as a compensation for machine-dependent error
curves caused by mechanical considerations and temperature, etc. These
data are entered by the machine manufacturer, stored in the MD user
directory and protected by password.
2. IKA data defining a workpiece
The function is used here to describe the contours of a workpiece in terms
of IKA data. Up to 16,000 interpolation points can be defined in a table. Up
to 32 IKA relationships (IKA data records) are supported.
This function can be used to generate complex contours using a burst of
interpolation points.
Machine manufacturer
The IKA function must be configured by the machine manufacturer. Please
refer to the machine manufacturer’s documentation for further information.
Caution
The IKA is not included in the actual value display.
