Abstract
In a method for monitoring an operating behavior of a tool holder, a resultant measurement axis signal is calculated using at least two measurement axis signals of at least two radially oriented measurement axes of a sensor provided in the tool holder. The monitoring is performed using the resultant measurement axis signal or the resultant.
Claims20
A method of monitoring an operating behavior of a tool holder, the method which comprises:
- providing a tool holder configured for rotation about a tool holder axis of rotation defining an axial direction, the tool holder, at one axial longitudinal end thereof, having a tool section with a tool-receiving formation for receiving a tool and, at another axial longitudinal end thereof, having a coupling section with a coupling formation for a torque-transmitting coupling to a machine spindle of a machine tool, the tool holder further having a measuring apparatus for acquiring data relating to an operation of the tool holder, the measuring apparatus being a sensor with at least two measurement axes that are oriented substantially radially with respect to the tool holder axis of rotation;
- outputting by the sensor at least two measurement axis signals associated with the at least two measurement axes;
- calculating a resultant R, being a resultant measurement axis signal, using the at least two measurement axis signals;
- and
- monitoring the operating behavior of the tool holder using the resultant R.

An intelligent tool holder, comprising:
- at least one tool holder that is configured for rotation about a tool holder axis of rotation defining an axial direction, said tool holder, at one axial longitudinal end thereof, having a tool section with a tool-receiving formation for receiving a tool and, at another axial longitudinal end thereof, having a coupling section with a coupling formation for torque-transmitting coupling to a machine spindle of a machine tool;
- a measuring apparatus for acquiring data relating to an operation of said tool holder, said measuring apparatus being a sensor with at least two measurement axes that are oriented substantially radially with respect to the tool holder axis of rotation, said sensor being configured to output at least two measurement axis signals assigned to the at least two measurement axes;
- and
- an evaluation unit being configured to calculate a resultant R, being a resultant measurement axis signal, using the at least two measurement axis signals, and said evaluation unit being configured to monitor the operating behavior of the tool holder using the resultant R.
