Machining
Module
Outcomes
1. Be able to analyze machining and
material processes based on scientific principles, engineering challenges, and
engineering practice.
2. Be able to determine appropriate
machining and material processes for applications by justifying the selection
as compared to alternatives.
3. Be able to identify an
appropriate sequence of operations.
4. Be able to do cost-benefit
analyses related to machining and material processes.
Preparation
ð
The
introductory section from Chapter 20 in the text, provides a good overview of
machining/material removal processes. The definition of machining (p522-3) and
figures 20.1 and 20,2 provide concise summary of
machining and where machining fits into material removal processes in general.
I thing the disadvantages listed on page 524, could be opportunities for
measuring productivity. Section 20.1 should be read in its entirety. Pay
careful attention to Figures 20.3, 20.5 and equation 20.1. Limit the focus in
20.2 to pages 531-2 (chip formation). Section 20.4 should be read in its
entirety, connect equation 20.1 with the equations for power and energy
consumption. Chapter 21 should be read up to and including Section 21.6. This
is probably the best introduction to machining I have seen. Read the
introduction to Chapter 22 and Section 22.1. We will connect tool life, to
section 20.4 and eqn 20.1. Chapter 23 should be
reviewed. Connecting economic considerations will be a key part of the
project.
ð
The
following videos from the text provide great examples of: Basic
Lathe Operations (Turning, Drilling/Boring/Reaming, Facing and Parting), the
2 types of hole making , the versatility of Milling As you view these I suggest you elaborate on
the notes you took from the reading.

Machining
Experiences Provided for Freshmen at Kettering. Focus
not only on how the processes relate to machining in general, but on the
details of the procedures. You may want to compare these to your notes from the
reading and the videos. You may want to refer to these later in the course when
ISO and Safety are discussed.
