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.
