Cycle Time Reduction For CNC Machining & Turning Centers
Help local industry reduce the time it takes to complete production runs!
During any CNC machines usage, there are really only two
activities. Either machines are in setup or they are running production. Setup
time is the total time the machine is down between production runs. Cycle time
is the time it takes to complete a production run divided by the number of good
When machines are in production, they are, of course, being productive. But
anything that can be done to reduce the time it takes to complete a production
run will - in turn - reduce cycle time. And of course, will improve the
machine's overall utilization.
Traditionally, CNC users have not had to run CNC machines at peak potential.
The sheer productivity of CNC machines (compared to their manual counterparts)
has thrilled many a CNC user. However, things have been changing in the
manufacturing environment. Lot sizes are shrinking. Lead times are shorter.
Quality expectations are higher. And of course, operating expenses must be
All of this requires CNC users to provide faster turn-around for the
workpieces they produce and a big part of faster turn-around is related
to reducing the amount of time that machines take to complete a production run.
All CNC users should have a strong interest in cycle time reduction. The
larger the lot sizes, the more important it is to reduce cycle time. Even
people with years of experience will be interested in finding new ways to
minimize cycle time, meaning you should be able to draw from very large student
base, dramatically increasing the number of potential students for your CNC
This course will allow you to relate the cycle time reduction from the
ground up. The objective of this course curriculum is to help instructors
relate concepts, techniques, and ideas that will help students go back to their
companies and implement a successful setup reduction program.
The course will be presented in three modules.
Discussion of basic premises, reasons why cycle time must be reduced, and
general introduction to the course
2: Cycle time reduction principles
The two task types related to running production, the three general ways to
reduce cycle time, and the four-step procedure to reduce cycle time
3: Cycle time reduction techniques
Countless techniques to reduce cycle time for CNC machining centers and
turning centers in several categories, including preparation &
organization, workpiece loading, program execution, workpiece
unloading/unloading, maintaining production, sizing adjustments, and dull tool
Be sure to download samples for
this curriculum. Samples include all written instructors materials,
samples of the slide shows, and samples of the student materials.
CD-rom disk including all instructor materials - The disk includes
the following instructor materials: Written documentation: Getting
started with the machining center curriculum - provides information
about how we intend the curriculums to be used. Setup reduction planning forms,
and exercises & answers.
All written documentation is provided in Adobe Acrobat format (PDF files) on
disk one in the folder named Written documentation. In order to view/print
them, you must have Adobe Acrobat Reader installed on your computer. We also
provide this software on disk one in the folder Adobe Acrobat Reader. Note that
all written documentation provided on the CD-rom can be freely printed, copied
Microsoft PowerPoint slide presentations - PowerPoint is fast
becoming the presentation software of choice by most presenters. Presentations
in this curriculum total over 450 slides to provide your visuals for the
course. Every step along the way, there's a highly colorful graphic or
animation to help you make your points!
Microsoft PowerPoint Viewer - Though we highly recommend that you
have the actual PowerPoint software, we do include the PowerPoint Viewer. It
does allow you to display the slide shows, but youll have no way to
modify them. Additionally, the slide shows are quite long (some over 300
slides). PowerPoint Viewer does not allow you to move around in the slide show
nearly as easily as the actual PowerPoint software does.
Ability to print the slide show hard copy - PowerPoint allows you to
print a hard copy of each slide show (Microsoft calls this printing handouts).
This may help you prepare if you dont always have a computer available.
You can include 4, 6, or 8 slides per page.
Free phone assistance - Again, theres a lot of information in
this curriculum. If you have questions about any topic while your preparing to
teach the course, we welcome your phone calls (847-639-8847). Or email us at
What you'll still need
In order to show the PowerPoint slide presentations to a group of people,
you need the following items.
A computer with Windows 95 (or higher) - Any current model
computer will work. If using a desktop computer, you can easily watch the
monitor of the computer (facing your audience) to see the slide show as slides
are displayed behind you by the projection system. Since the left mouse button
advances the slides, you even have a remote slide advance button (as is
commonly used with a 35 mm slide projector). If portability is an issue, keep
in mind that many of the notebooks and sub-notebooks have ample power to run
the presentation software. However, be careful in your selection. Many
notebooks do not allow you to send data out through the VGA port and see the
slide show on the LCD screen of the notebook at the same time. Without this
ability, you may have to turn around to see your slides, which can be
distracting to your audience.
Microsoft PowerPoint Software (PowerPoint 2000 was used to create
the slide show) - Though you can display all presentations with PowerPoint
Viewer (included with this curriculum), you will need Microsoft PowerPoint if
you intend to modify the slide shows given in this curriculum. We highly
recommend that you have this ability. This software can be found in any
computer store for a price of about $250.00 (it also comes with Microsoft
Office). You will find this to be a very powerful presentation generating
program; one you can use to develop your own slide shows for other courses (or
of course, modify those in this course curriculum).
A way of displaying the screen show - You have several alternatives
in this regard. All involve using a device that takes data from the VGA port of
your personal computer. First, many schools already have a projection system
that can display information from a personal computer. Basically, anything that
can be shown on the computer screen can be displayed through the projection
system. Second, you can use a device that sits on top of an overhead projector
to display your screen shows. In essence, this device makes a transparency of
what ever is on the display screen of the computer. Third, and especially if
price is a concern, you can use a simple scan converter (about $200.00 -
$300.00) and display your screen show on any television that has a video in
connector (as most do). If you must use the RF connector of the television
(where an antenna plugs in), an RF converter must be purchased. Since there are
so many alternatives for displaying your slide shows, we welcome phone calls
(847) 639-8847 if you have questions about your alternatives.
This curriculum is FREE with your initial textbook order!
Not only will you be teaching with the best state-of-the-art CNC curriculums
in the industry, youll be doing so free of charge! All we ask is that
your school bookstore buys the student manuals from us! With an initial order
of just 20 manuals, well ship the instructors materials free of
charge! All instructor materials (slide shows, PowerPoint Viewer, instructors
manual, and Adobe Acrobat Reader to view/print the manual) come on the cd-rom
disks. Our net price to your school (or bookstore) for manuals is $40.00 each
for the student manual. Future orders can be in any quantity. This cost will be
recovered, of course, as students enroll in your classes and buy the manuals.
In essence, your first 20 students will be paying for the curriculum!
