CNC Lathe for Student Conducted SPC Experiments

9451757怀特这项提案是关于一台数控车床，使机械工程专业的初级学生能够进行他们自己的程控实验。该车床的主要应用将在初级机械工程必修课程《制造方法》中进行。拟议的数控车床将用于本课程的SPC模块。使用车床，学生团队将进行一项实验，以确定制造过程是否有能力并处于可控状态。每个学生小组必须确定应该测量什么以及如何测量。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，所要求的数控车床有一台板载计算机，可对其进行编程以生产“好的”或“坏的”相同的零件。后一个方面是学生能够确定诸如进给速度和主轴速度等变量对过程控制的影响所必需的因素。这是目前大多数机械工程课程中的一种独特的方法(也是缺乏的)。在数控/CAM和SPC方面的知识和实践经验是当今机械工程毕业生计划在制造业发展的关键工具。

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.
