Abstract: In some examples, a material removal system may control movement of a material removal machine based on whether a material removal tool is in contact with a sample. A material removal system may include a material removal machine (e.g., saw, grinder, polisher, and/or more general material preparation and/or testing machine) that is configured to move at the urging of one or more actuators. The system may further include control circuitry configured to control movement (and/or speed, acceleration, etc.) of the material removal machine (e.g., via the actuators) based on one or more power, thermal, position, and/or other parameters that indicate whether the material removal tool of the material removal machine is in contact with a sample.

Abstract: A method for controlling a sawing machine with a sawing tool, which is driven by an electrical sawing tool drive with a first frequency converter, and with a sawing feed device for moving the driven sawing tool at a feed rate in relation to a workpiece to be sawn, and also to such a sawing machine. The feed rate is changed over from an idling feed rate to a working feed rate when the sawing tool engages in the workpiece. A value of a physical variable which corresponds to the torque transferred from the sawing tool drive to the sawing tool or from which a change in this torque can be calculated is determined here at the first frequency converter. The changeover from the idling feed rate to the working feed rate takes place in dependence on the value of this physical variable.

Abstract: A band saw machine for sawing metallic workpieces, having a lower saw part and an upper saw part with two carrying wheels mounted therein, and a saw band that revolves with a cutting motion around the wheels that passes through a cutting region. A feeding device attached to the lower saw part feeds workpieces to the cutting region and/or into a sawing plane, in which the cutting region of the saw band is moved in a saw advance motion. The feeding device has a movable holder for detachably fastening the workpiece, and the holder, starting from an initial position, is movable both with translational and rotational motions. The saw band is guided through the cutting region, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. Here, the workpiece is preferably turned by the holder such that its upper side faces downward.

Abstract: A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.
