A calibration tool for a coffee grinder can receive an image from a camera. The image can depict coffee grinds produced by the coffee grinder. The calibration tool can analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds. The calibration tool can determine whether the representative grind size of the coffee grinds deviates from a predefined reference size by at least a threshold amount. In response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, the calibration tool can output an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size.

The invention relates to a method for controlling an automated orbital sander, in which method an electrically powered orbital sander is moved around automatically, at constant pressure, over the surface of an object, along at least one predefined sanding path so as to perform sanding, characterized in that the instantaneous power consumed by the sander along the sanding path is measured and in that the measurement thus taken is processed in order to deduce therefrom information regarding the level of abrasion along said path and/or to detect any sanding incident that has occurred along the latter.

The present disclosure provides a monitoring device, a monitoring method and a device for cutting a display substrate. The monitoring device includes an infrared temperature detection module configured to detect a temperature at a contacting position where a cutter wheel is in contact with the display substrate when cutting the display substrate with the cutter wheel, so as to acquire a temperature parameter at the contacting position; and a processing module configured to generate, based on the temperature parameter, a corresponding control parameter for controlling the process of cutting the display substrate.

A calibration tool for a coffee grinder can receive an image generated using a light detection and ranging (LiDAR) system. The image can depict coffee grinds produced by the coffee grinder. The calibration tool can analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds. The calibration tool can determine whether the representative grind size of the coffee grinds deviates from a predefined reference size by at least a threshold amount. In response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, the calibration tool can output a notification associated with the deviation. The notification can include an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size.

A method for grinding bevel gears (1), wherein a first grinding tool (2) is used during a first method section and a second grinding tool is used during a second method section. A measurement system (30) is used to carry out a measuring procedure, in which sampling values can be ascertained for at least a part of first flanks of the bevel gear workpiece (1), which enable a statement about the concentricity error of this bevel gear workpiece (1) in the present chucking. Concentricity correction dimensions are ascertained by computer on the basis of the sampling values, and an adaptation of machining movements of the second method section is performed on the basis of the concentricity correction dimensions.
