THE MACHINE SHOP AT HESS LABS

• WHERE YOUR CREATIVE IDEAS BECOME REALITY

2

• Dear Students,
• Hi my name is George Carenzo. I was asked by Mark
  Shiber and your professor to share with you some
  of the work we create here in the machine shop,
  and the services we provide. Im curious to know
  if anyone has seen or been in the machine shop.
  Well, as you will see from the slide show, they
  illustrate various mechanical components created
  in a machine shop such as medical devices, molds,
  lens holders, nozzles, and sequence valves.
• The components shown are made using a wide
  variety of materials. The machines we use are
  vertical and horizontal milling machines, lathes,
  drill presses, surface grinders, sheet metal
  cutters, and a nifty wire EDM machine. The photos
  you will see are prototypes and special
  components based on the designs created by
  students and researchers. At the machine shop, it
  is not so much that we make a part or a component
  from a drawing. Our basic mission is to ensure
  that the part or component in question is what
  the student or researcher had envisioned. This is
  what challenges us practically every day.
  Especially when students, even with the best of
  intentions, bring with them a drawing that does
  no reflect his or her vision.
• Now most people assume that a machinist sticks a
  piece of metal in a machine and cuts it. This is
  quite far from the truth. Cutting a piece of
  metal is relatively easy. What makes our job a
  challenge is discovering genuine solutions to
  your particular part or component. When I say
  that, as research machinist, our combined
  experience can provide you with design solutions
  it is because we base our experience on reality.
  This is to say, we have discovered time and time
  again, what works in a part or component and what
  does not.
• We realize that most students who embark in
  designing something, it is often based on a
  theory -which is understandable. But it is also
  based on their subjective knowledge of the
  problem at hand, hearsay, or misinformation. We
  see a lot of this in the drawings that are
  submitted. It seems to me that if you want to get
  the most of the services we provide, the best way
  to communicate with us is through a good drawing.
  The adage a picture is worth a thousand words
  could not have been said any better when working
  with mechanical drawings and submitting them to a
  Research Machinist. So, if you want us to get
  your part done, accurately, efficiently, and in a
  timely manner, give us a good mechanical drawing.
  It is, ultimately, the best way to communicate.
  So if you are in earnest to become a mechanical
  engineering designer, I strongly suggest you
  develop a good habit in making drawing that
  reflects the level of your expectations.
• Now I realize that you, as students, did not come
  here to be draftsmen. However, and realizing that
  you most likely need parts made in a timely
  manner, giving greater attention to a mechanical
  drawing complete with tolerances and the like
  will, in the long run, save both of us much time
  and effort in completing your design request.
  From our experience, considerable time and effort
  is needlessly wasted when drawing are submitted
  with missing dimensions, off scale, no
  tolerances, or a mistaken dimension. I cannot
  empathize this enough. Id also like to say that
  there have been many occasions in which a
  researcher spends an inordinate amount of time in
  his or her design project, only to discover upon
  our observations that it was not going to work
• In this respect, I strongly suggest you seek the
  advice of Mark Shiber and even the Research
  Machinist in the shop during your design project
  especially if it requires substantial machining
  or if you find yourself feeling uncertain of your
  design ideas.
