The fastening tool process controller (40) provides an apparatus and process for programming, controlling, and comparison validation of the semi-automated operation of a transducer (32) equipped and/or non-instrumented, pneumatically driven impulse or impact tool to a repeatable final shutdown torque value. The controller (40) is taught a supply line pressure to output torque ratio for the particular pneumatic tool (22) being used by validation against a NIST traceable standard torque transducer (32), or through manual checking with a normal torque wrench. This process is referred to as an automatic or manual teach cycle. The ratio provides the controller (40) with the final required line pressure needed to achieve the pre-program torque targeted value. |
