9451757 White This proposal is for a CNC lathe to enable junior mechanical engineering students to conduct their own SPC experiments. The major application of the lathe will be in a required junior level mechanical engineering course titled Manufacturing Methods. The proposed CNC lathe would be used in the SPC module of this course. Using the lathe, student teams will conduct an experiment to determine if a manufacturing process is capable and in control. Each student team must determine what should be measured and how to make the measurements. The CNC lathe permits the timely replication of a sufficient number of parts required for these experiments. Additionally, the CNC lathe requested has an on board computer which can be programmed to produce "good" or "bad" identical parts. This latter aspect is a necessary ingredient for the students to be able to determine the effect of variables, such as feed rates and spindle speeds, on process control. This is a unique approach (and something that is lacking) from most current mechanical engineering curricula. Knowledge and practical experience in CNC/CAM and SPC are critical tools for today's mechanical engineering graduates planning to pursue a career in manufacturing.

这个建议是一个数控车床，使初级机械工程专业的学生进行自己的SPC实验。车床的主要应用将在初级机械工程课程“制造方法”中进行。提出的数控车床将在本课程的SPC模块中使用。使用车床，学生团队将进行实验，以确定制造过程是否有能力和控制。每个学生小组必须决定应该测量什么以及如何进行测量。数控车床允许及时复制这些实验所需的足够数量的零件。此外，要求的数控车床有一个机载计算机，可以编程生产“好”或“坏”相同的零件。后一个方面是一个必要的因素，使学生能够确定变量的影响，如进给速度和主轴速度，对过程控制。这是目前大多数机械工程课程中独特的方法（也是缺乏的）。CNC/CAM和SPC的知识和实践经验是当今机械工程专业毕业生计划从事制造业的关键工具。
