Caz HS Tech Labs Gets a Faro 3D Laser Scanner

Cazenovia students will be able to utilize a Coordinate Measurement Machine in the near future. This device is used for measuring the physical geometrical characteristics of an object and is manually controlled. It is a 7 degree of freedom arm with a laser end effector that you could use to scan objects. You can then scan an object, bring it into 3D modelling, and modify it or 3D print it. A brief overview of this CMM can be downloaded HERE.

They are used in industry to reverse engineer parts, produce highly accurate 3D models, and for inspection of manufactured items.  It is widely used in many industries including:
  • Aerospace: Alignment, Tooling & Mold Certification, Part Inspection
  • Automotive: Tool Building & Certification, Alignment, Part Inspection
  • Metal Fabrication: OMI, First article inspection, Periodic Part Inspection
  • Molding/Tool & Die: Mold and Die Inspection, Prototype Part Scanning

Students in the Engineering & Technology programs will be able to utilize this piece of equipment in many different ways including scanning to a 3D print, and parts inspection in Computer Integrated Manufacturing class. Students in the Intro to Engineering Design class would be able to use it to measure parts in the reverse engineering unit of the course. It may even be an interesting tool for art students as well!

A parent of a former student has donated the device which he uses in all aspects of the product development in his company MCM Design, Inc.  This is a local company doing global design work right here in Cazenovia. One of the goals of this small local company is to develop products to be manufactured cost effectively in the U.S.A.  What better way to do it than pass down technology to the people who will be using it in the future: our high school engineering students! We will be highlighting this company and the work they have done at a later date.

Here’s a cool idea for a project with it from Jay Leno: (This is the company that manufactures the arm that we are getting as well!)

POE Simple Machines

So you need a little help learning how to do lever problems, huh?  Below are a bunch of of videos that show how to do the problems in the Levers & Wheels presentation, step by step. Watch it once, or as many times as you like. Please let me know if you have any questions!     Continue Reading

How Accurate is the Dobot Magician?

Question:

Just how accurate is the Dobot Magician?

Answer:

Short answer: very accurate. To 0.007″ to be exact. Verified by an independent study student of mine using statistical analysis.
3bots In May of 2017  I purchased a Dobot Magician from an Etsy shop, as that was the only way to get them at the time. It is now available at In-Position Technologies here for $1499.00.  Use the code “chrisandjimcim”  or mention us on your PO and you will get free shipping as well as US based help and warranty service!
First thing I did, and when I say I, I mean an Independent Study student (props to Vincent Paglia , who will be going to RPI in August, see his info below!) was do an Accuracy test. They claim it is accurate to 0.2 mm, and our test on our robot proved that it was actually more accurate than that.  Try that with the robot you use for CIM class now! The only one more accurate in my classroom is my Fanuc, and it cost almost 15 times what the Dobot cost!

  For those of you into POE and “data” you can you download the spreadsheet with data points, graphs, ect here: 2017 Dobot Repeatability Data.  But this histogram says it all:
Dobot Accuracy Graph When all was said and done, our robot was accurate to about 0.18mm overall. That is 0.007″ for those of you in England… I must say, very impressed with the accuracy.

_MG_5137-4Special thanks to one of my best ever Independent study students for all of the work he did this year with me  with the Dobot. 
Vincent Paglia, son of Thomas and Regina Paglia, has been awarded a scholarship from SME. He plans to study engineering at Rensselaer Polytechnic Institute in the fall.  Vincent has played varsity and JV soccer; has played hockey at Center State for four years at the bantam and midget levels and for the high school as a senior; and is also a member of the Tech Club and National Honor Society.  He received the Rensselaer Medalist Award for outstanding achievement in math and science in 2016 and was also a Scholar-Athlete by the New York State Public High School Athletic Association (NYSPHSAA) while playing soccer and hockey.
