First off I want to apologize I titled last week’s post “Week 1”, when by my counting, last week was Week Zero. Opps! I hope there won’t be too much confusion.
This week will be a busy Week 1 in ME1800. We have 3 lectures, reading assignments to do, homework assignments due, and we will start labs this week. This week we will introduce the topic of Lean Manufacturing which will be a recurring theme through out this course. Following that introduction we will spend the rest of the week examining the Process Variables in Manufacturing Engineering (specifically those associated with machining,) In Manufacturing Science these are considered to be the independent variables. These are the things we get to control as manufacturing engineers. In lab you will begin the process of becoming familiar with the CNC machine tools we will use in the class and will experience the life as a Machine Tool Operator. There are several Assignments due this week
- Introduce Lean Manufacturing.
- Develop an understanding of PVs in Manufacturing and how to choose them.
- Get started with CNC machining in the lab

||Week 1 Quiz
||Week 2 Survey
This week in ME1800 we will form groups, and complete our first group assignment. In class we will finish up our discussion of Art to Part and PVs and then look at issues concerning quality and measurement. We will look at topics covering measurement tools and measurement uncertainty, develop inspection plans, discuss SPC and Quality Assurance, and begin a discussion of what might cause quality problems. In labs we will continue to practice operating the CNC mills and begin to introduce turning operations on the lathes, and will go into more depth in the CAM exercises.
In the Computer Lab area you will need to finish up CAM 1 Getting started if you haven’t already and complete the first part of CAM 2 Standard Milling Operations and features. You will learn how to create the G-Code that at the machines can read and a little about how to read it yourself sou you will at least know what the machine tool is about to do.
At the machines you will operate a mill with a little more opportunity to do something wrong than last week and depending on the schedule begin to familiarize yourself with the Haas Lathes we have i the lab. It is important for us at this point in the class for you to get a little out of phase with each other in the labs. Most lab exercises are available for longer than one week to make sure everyone has a chance to do each exercise.
