A feed unit for feeding a core drill bit into a work object

A method for controlling a feed unit for feeding a core drill bit of a core drill system into a work object, the feed unit comprising a feed motor and a control unit, wherein the feed motor is arranged to be connected to a device for feeding the core drill bit into the work object, and to be controlled by the control unit via a motor control interface,

• wherein the method comprises:
• obtaining a computer implemented classification model, wherein the classification model is configured to classify a material currently engaged by the core drill bit into a pre-determined set of materials based on obtained data associated with the motor control interface and/or based on data obtained from one or more sensors arranged in connection to the feed unit,
• determining a material currently engaged by the core drill bit based on the classification model and the obtained data, and
• controlling the feed motor based on the determined material.

A concrete processing system comprising a core drill system and a remote control device,

• the core drill system comprising a feed unit with a feed motor and a control unit wherein the feed motor is arranged to be mechanically connected to a device for feeding a core drill bit of the core drill system into a work object, and to be controlled by the control unit via a motor control interface,
• wherein the control unit is arranged to communicate with a remote control device and to control the feed motor based at least in part on control commands received from the remote control device,
• wherein the control unit is further arranged to determine a material currently engaged by the core drill bit based on a computer implemented classification model and based on obtained data associated with the feed unit,
• wherein the control unit is arranged to adjust the control commands received from the remote control device for controlling the feed motor based on the material currently engaged by the core drill bit.
