German M. Chistokhodov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Machine tool with vibration detection
    Patent number: 9737968
    Abstract: A method of detecting machine tool vibration is provided. The method includes receiving, from a sensor arranged in a machine tool, motion data measured along an axis. The method also includes comparing the motion data against a first threshold. The method also includes adjusting a counter if the motion data has a magnitude greater than the first threshold. The method also includes generating an alarm if the counter is greater than a second threshold.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: August 22, 2017
    Assignee: Haas Automation, Inc.
    Inventors: Razmik G. Petrossians, Joseph V. Soliman, Puneet Gupta, German M. Chistokhodov, Barry D. Johnson

  • Systems and methods for decelerating a motor in a computer numerical controlled machine tool
    Patent number: 8299742
    Abstract: A method for decelerating a motor in a computer numerical controlled machine tool is provided. The method includes calculating a present rate of deceleration DP, for a motor of a motor drive system, based on a present speed SP of the motor, a reference speed SR of the motor, and a reference rate of deceleration DR of the motor. The method also includes decelerating the motor from SP according to DP. The motor drive system comprises a maximum power rating that defines a maximum power, generated by the motor while decelerating, that can be dissipated without overloading the motor drive system. DR is a rate of deceleration such that power, generated by the motor while decelerating from SR according to DR, is equal to the maximum power rating. Power, generated while decelerating the motor from SP according to DP, is equal to or less than the maximum power rating.
