Question

The quality assurance manager is assessing the capability of a process that puts pressurized grease in an aerosol can. The design specifications call for an average of 60 pounds per square inch of pressure in each can, with an upper specification limit of 65 psi and a lower specification limit of 55 psi. A sample is taken from production and it is found that the cans average 61 psi, with a standard deviation of 2 psi. Also, the process will stop if the process starts making cans that are more than three standard deviations above or below the average. What is the capability index of this production process?

Answer 1

A sample is taken from production and it is found that the cans average 61 psi with a standard deviation of 2 psi.

Step-by-step explanation:

After the checks of the QC manager, it is deduced that a sample is been taken from the production and it is also found that the kergs average 61 psi woth a standard deviation of 2 psi.

Hydraulic fittings are available in threaded, thread-forming, rivet and drive styles. They are available in different angled configurations and a wide variety of extension lengths to allow you to position the fitting for easy access with a grease gun on different types of equipment.

Another factor to consider is the type of grease fittings used in the facility. Most fittings have a ball check in the head of the fitting, which prevents dirt from getting to the bearing. The spherical contour of the fitting head provides a ball-and-socket joint between the fitting and the hydraulic coupler of the grease gun. The most common fitting is the hydraulic fitting, available in standard and metric sizes.
