  • Patent number: 8845245
    Abstract: A dampened spindle cartridge and a dampened spindle adaptor are provided for damping tool vibrations during operation of a machine tool. Damping media is arranged inside a cavity formed within the spindle adaptor or the spindle cartridge. The damping media may be a solid aggregate, such as steel shot or sand, or a viscous fluid, such as oil. The damping media attenuates and/or converts tool vibrations into friction and heat, thereby dissipating vibration energy generated during cutting operations performed by the machine tool and prevents reinforcement of the forced vibration.

  • 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.

  • Patent number: 8269645
    Abstract: Rule based display systems and methods are provided. In an aspect of the disclosure, a display screen is dynamically generated using one or more display boxes selected from a plurality of display boxes stored in memory. Each of the plurality of display boxes has rules associated with the display box. To generate the display screen, a rules module generates a set of conditions based on current conditions of the system. The rules module then compares the rules of each display box with the set of conditions to identify display boxes having rules that are satisfied by the set of rules. A display module then generates the display screen using the display boxes identified by the rules module, thereby dynamically generating the display screen.

  • Patent number: 7603943
    Abstract: A linear actuator for a rotating shaft assembly includes a cylinder and a piston arranged within a cavity defined by the cylinder. Faces of the piston delimit first and second chambers within the cavity. A rotatable shaft fixed to the piston defines a first main passage in fluid communication with the first chamber and a second main passage in fluid communication with the second chamber. A pressure delivery body rotatably fixed to the rotatable shaft defines a first delivery passage in fluid communication with the first main passage and a second delivery passage in fluid communication with the second main passage. A passage isolation system selectively isolates fluid communication between the first delivery passage and the first main passage and fluid communication between the second delivery passage and the second main passage. A pressure limiting system selectively blocks fluid communication through the first and second main passages.
