Component Used of Power Transmission Assignment

Assignment Task

In Assignment 2 you are expected to review the brief below, become familiar with the data presented in the table, analyze it and answer the following questions. The assignment should be in the format of a report, following all relative academic guidelines.

Brief

A component used as a part of a power transmission unit is manufactured using a lathe.

Twenty samples, each of five components, are taken at half-hourly intervals. Within the flow of the day a number of (non-)technical incidents appear. These include taking a lunch break and adjusting or resetting the machine.

For the most critical dimension, the process mean ( x ¯ ) is found to be 3.500 cm, with a normal distribution of the results about the mean, and a mean sample range ( R ¯ ) of 0.0007cm.

With the above scenario in mind, and considering the data in the table below, complete the following tasks.

1. Use this information to set up suitable control charts.

2. If the specified tolerance is 3.498 cm to 3.502 cm, what is your reaction? Would you consider any action necessary?

3. The following table shows the operator’s results over the day. The measurements were taken using a comparator set to 3.500 cm and are shown in units of 0.001 cm. What is your interpretation of these results? Do you have any comments on the process and/or the operator?
