Project Mission Statement The mission of the project team is to theoretically develop a design for a simple turret index model. This design shall incorporate a torque motor and be used to evaluate the feasibility of future applications. The team shall conduct an extensive benchmark study as well as perform testing on competitors turrets published data. A feasibility evaluation resulting in design recommendations will be conducted. Upon review the team shall then develop the selected design in preparation for pilot builds.

Concept Development Main Drive – Torque Motor Top Plate – 12 Tooling Stations (off shelf) Coupler – Locks motor and top plate (off shelf) Piston – Connects top plate to coupler (off shelf) Housing – Cast iron, interface with x-y axis slides

Preliminary Concepts

Preliminary Concepts Continued

System Model Torque motor response to step input voltage Optimized around a single station to station index motion

Concept Evaluation Process Designs were evaluated based on the following characteristics. Indexing Time Static Stiffness/Rigidity Repeatability Weight/Volume Simplicity

Design Concerns Heat generation and removal Sealing the motor Bearings Static Stiffness Thermal Deflection Dynamic response to electrical input

Desired Outcomes Confirmation of published data using a validated experimental process. Verify the feasibility of Torque Motor implementation into CNC machines. Demonstrate competitive advantage through the use of Torque Motor.
