Show transcribed image text Problos No. 1: in a semi-automated work cell. As part of the process, a brass shell with a nominal volume of 2.5 cc is filled with thermally conductive grease. Next, a sleeve and the bimetallic thermal sensor element are submerged into the shell cavity. The fill process is designed to provide decidedly less than 2.5 cc. In the desired condition, the apparent volume of the grease as displaced by the sleeve and sensor element wili not exceed the shell cavity volume. Both the fi11 process and the brass shell manufacturing process are in control. An automotive supplier manufactures an engine coolant temperature sensor X-bar and R cha rts for the brass shells and the thermal grease filling process indicate the following: x-double-bar 2.8c R-bar 0.1 co Thermal grease fi11-volume: x-double-bar-2.6 cc R-bar0.03 cc Specifications for the brass shell cavity are set at USL-2.9 cc and LSL – 2.6 cc. Make a statement of process capability both as a probability of non-conformance and as a process capability index if appropriate. a.) b.) Specifications for the thermal grease volume are set at USL 2.56 cc and LSL 2.51 cc. Make a statement of process capability both as a probability of non-conformance and as a process capability index if appropriate. c.) What proportion of sensors will be under filled, i.e., have less than 2.51 ce of thernal grease?
