Abstract: Provided is a disclosure for a cutting device configured to control a linear speed of a cutting wheel as the cutting wheel gets smaller with use. In one example, the cutting device includes a cutting wheel; an actuator to rotate the cutting wheel; a power source configured to provide power to the actuator for rotating the cutting wheel at an adjustable rotational velocity; and control circuitry configured to adjust the rotational velocity of the cutting wheel to maintain a substantially constant surface speed.

Abstract: Methods and apparatus to control a fluid dispenser on a metallurgical specimen preparation machine are disclosed. An example system to dispense fluid for a grinder/polisher includes: a fluid dispenser having: a fluid reservoir to store a fluid, and a nozzle configured to dispense the fluid onto a grinding/polishing surface; a temperature sensor configured to output a temperature signal indicative of a temperature of the grinding/polishing surface during a grinding or polishing operation; and a processor configured to: compare the temperature signal to a threshold; and send a dispense signal to the fluid dispenser when the temperature signal satisfies the predetermined threshold, wherein the fluid dispense is configured to dispense the fluid in response to the dispense signal.

Abstract: A grinder/polisher comprises a specimen holder, a platen, an actuator configured to move at least one of the specimen holder and the platen, an input device, a machine readable storage device, and a controller. The input device includes a plurality of quick-recall inputs and is configured to receive grinding/polishing parameter inputs representative of grinding/polishing parameters, The grinding/polishing parameters comprise at least two of a cycle time, a platen speed, a specimen speed, a platen direction, a specimen direction, and an applied load. The quick-recall inputs are selectable on a same interface as the user parameter inputs. The controller is configured to save to the machine readable storage device a plurality of user-selected grinding/polishing parameters based on inputs received by the input device, associate the parameters with one of the quick-recall inputs, configure the parameters in response to selection of the quick-recall inputs, and perform an operation according to the parameters.
