Method Of Designing Tool And Tool Path For Forming A Rotor Blade Including An Airfoil Portion

View page
US Patent:
20100042244, Feb 18, 2010
Filed:
Oct 22, 2009
Appl. No.:
12/603629
Inventors:
Tahany Ibrahim El-Wardany - Bloomfield CT, US
Changsheng Guo - South Windsor CT, US
Daniel V. Viens - Mansfield Center CT, US
Eric Fromerth - Manchester CT, US
Lienjing Chen - Tolland CT, US
International Classification:
G06F 17/50
US Classification:
700 98, 700103
Abstract:
A method of designing a tool for forming a rotor blade including an airfoil portion includes generating a computer model of a rotor blade having an airfoil portion, and determining a curvature and radius of curvature at sections of the rotor blade. An inner and outer diameter of a circumferential forming portion of a tool operable to form the rotor blade may then be calculated. A method of designing a tool path for forming a rotor blade including an airfoil portion includes generating a computer model of a cylindrical tool operable to form a rotor blade including an airfoil portion and of a rotor having a plurality of the rotor blades. The computer models of the rotor and tool are used to generate a first and second tool motion corresponding to airfoil suction and pressure portions. A method of forming a rotor with integral blades is also disclosed.

Method And Apparatus For Machining Parts With Variable Stiffness

US Patent:
20200206851, Jul 2, 2020
Filed:
Jan 2, 2019
Appl. No.:
16/238167
Inventors:
- Farmington CT, US
Zhigang Wang - South Windsor CT, US
Eric Fromerth - Manchester CT, US
International Classification:
B23P 15/02
B23C 3/18
Abstract:
A method and apparatus for machining parts with variable stiffness includes determining, by a controller, a chatter-lobe plot of a cutter assembly. A preliminary tool path is developed by the controller. Virtual machining of a blank part using the preliminary tool path is performed by the controller. A chatter-lobe plot of the virtually machined part is determined by the controller. A dynamic chatter-lobe plot using the chatter-lobe plot of the cutting tool assembly and the chatter-lobe plot of the virtually machined part is determined by the controller. A chatter-free rotational speed of the cutting tool from the dynamic chatter-lobe plot is determined by the controller. A machining apparatus, controlled by the controller, uses the determined chatter-free rotational speed of the cutting tool to machine a blank part.
