Project involves the design of a micrometer type (a.k.a "click style") hand torque wrench. Must be familiar with the principles involved in this kind of tool to ensure accuracy and repeatability of results. The ratchet head will be purchased “complete” and attached to the tool, along with other interchangeable head styles. This design activity involves only the handle and torque measurement mechanism needed to produce reliable results and ease of use, design of the individual torque heads are not part of the project.
Accuracy must be +/- 2% and the overall design must comply with ANSI B107.14 standard (copy can be provided for this project). After assembly this tool will be calibrated and certified traceable to NIST, and must therefore employ a design which is at once simple, accurate and durable in order to pass calibration and provide years of use for the end users.
Design will involve working closely with us concerning all “purchased components” such as springs and screws etc....
