Induction coil assembly, method for monitoring an inductive heating process for an induction coil assembly, self-learning system for monitoring an inductive heating process, and method for training the self-learning system

A method for monitoring an inductive heating process for an induction coil assembly with a sleeve portion of a tool holder inserted in an induction coil of the induction coil assembly, the method comprising:

• providing one or more different characteristic variables of the induction process, the one or more characteristic variables including at least one variable selected from the group consisting of a coil current, a coil voltage, an input current, an input voltage, a link circuit current, and a link circuit voltage;
• supplying the one or more characteristic variables to a learning system, using the one or more characteristic variables by the learning system to ascertain a monitoring characteristic variable, the monitoring characteristic variable being a variable selected from the group consisting of a temperature characteristic variable of the sleeve portion inserted into the induction coil, a sleeve characteristic variable of the sleeve portion inserted into the induction coil, and a time characteristic variable for the heating process of the sleeve portion inserted into the induction coil;
• and
• monitoring the heating process using the monitoring characteristic variable, including at least one of the temperature characteristic variable, the sleeve characteristic variable, or the time characteristic variable.
