We have always loved our CNC vacuum table that came with our Multicam machine. We have t-slots on 2 of our other machines and dread every part of holding down parts. That was until we created our own t-slot hold downs (info available on our website here). Since the use of these holdowns, we have not only accepted t-slots as a viable option, but have found that they offer advantages in certain situations. The problem I have with most hold downs is the fact that they cover up some of the cutting surface. Ours do not.
As a high school teacher and user of equipment with teenagers, I feel that we know how to abuse tools. Like all reviews, each reviewer is sharing their personal perspective. This review comes from the perspective of lots of users doing a huge variety of projects with a variety of materials. This isn’t a review from a production shop, but rather a learning atmosphere. Over the last 2 years, we have fired up the CNC plasma about 400 times. We get a lot of use out of the tool.
I have spent a great deal of time pondering the definition of my class. I frequently am asked about what I teach and quickly look for a way to explain to someone without having to give too much background knowledge. By class name definition it is a manufacturing and engineering course. It is still the best term to use, but it leaves much to be desired by interested groups that don’t have manufacturing experience.
You can now buy shirts and sweatshirts with our logo on it! I am planning to buy a bunch of shirts in bulk to bring the cost down, but you are more than welcome to order your own from here.
We finally worked out a new logo. Looking to make class shirts and such.
Here is the new sign for outside our classroom. We CNC plasma cut it out of some 1/8 steel.
I liked this student’s project and wanted to document what he did so that other students could use some of his work. The thing that impressed me was his use of a 3D model in the CNC carve, his use of texture and modeling. We did a piece similar before, but used a different texture.
I stopped by a machine shop garage sale on my way home from work and learned that the machine shop was closing due to retirement. Dwight Koch was closing down his machine shop. He was kind enough to donate some end mills and other miscellaneous parts to our program. It is wonderful how much local businesses support programs like ours. Thank you to all that have helped us out over the years and I wish Dwight the best retirement. Thanks again.
We have known about designing boxes and cabinets in Solidworks and then cut the parts out on the CNC for some time, but we hadn’t made it happen yet. I love this system because it takes the best of both softwares and helps create awesome work. Solidworks handles the Assemblies so well and Vectric Aspire handles the vectors and post-processing for CNC so well. Continue reading

We have so much material to cover in our beginning manufacturing and engineering class that we don’t get very in depth their first year. It is mostly an introduction and some hands on experience, practice and then move on. This is true for our Arduino unit. This is most students first experience with electronics and coding, so we start simple.
This is not a how to use the Arduino, but rather a how I teach Arduino.
