I’ll say right at the outset: “It ain’t for the money.”
What do I mean by that? Read on . . .
For several years I have been interested not only in education in general, but how I might get actively involved, especially at the high school level in math and/or science. No, I have never been a teacher in a formal sense, and no, I don’t have a teaching credential either. Even though I had the will and desire to become a teacher, unless I had a teaching license issued by the state of Colorado, my options were limited.
Sure, I could have been a volunteer or a private tutor, but for me these options were limited in scope, responsibility, and personal satisfaction. I thought earlier this year that I was at a dead end until I remembered an ad I had seen and saved a couple of years ago about a program called Denver Math Fellows. This program is the first large-scale tutorial program integrated into the school day to be implemented district-wide in Colorado schools.
The concept and possibility of becoming a Denver Math Fellow (DMF) really piqued my interest because one of the primary qualifications was a college degree in virtually any field (mine’s in industrial design). This was good for me because I had never been a teacher before. Other qualifications include the desire to help students close the opportunity gap in math, as well as committing to at least a one-year term of service — in my case August 2015-June 2016.
Below is a slideshow/video of some the orientation and training I did before becoming a Denver Math Fellow — just click anywhere in the photo.

ANSYS, a major provider of engineering simulation (CAE) software, announced that it has acquired substantially all the assets of Delcross Technologies, a developer of computational electromagnetic simulation and radio frequency system analysis software.
The acquisition is intended to let ANSYS users to understand how antennas interact within their operating environments and how this behavior affects the system’s overall ability to transmit and receive data without interference. As usual, and not surprisingly, terms of the deal, which closed earlier this week, were not disclosed.
So, what does this really signify? Simulating not just large-scale antenna systems, such as those found in giant aerospace projects (which will surely go on after the acquisition), but on a much, much smaller scale for Internet of Things (IoT) projects.
Although it’s almost a year old, below is a video presentation (click on the image) from Delcross Technologies for modeling installed performance of antennas on electrically large platforms, such as aircraft and automobiles.

It’s obviously no secret that 3D printing continues its march on dominating the world of 3D physical realization. In the past year I’ve personally seen 3D printers at Office Depot, UPS, FedEx, and Staples where you can bring in an STL file on a USB drive and, theoretically, come back in a few minutes or hours with a 3D product of your creation.
From what I’ve seen, I haven’t exactly been overly impressed with the results. Between under-trained store staffs, limited choices of processes and materials, and just plain bad designs, the end product and process still leave a lot to be desired. In other words, it’s a hit or miss proposition, and probably more of the latter.
Honestly, if you’re serious about the result, take your design to a 3D printing service bureau with more process and material options, not to mention a professional, experienced staff who understands those important issues, but good design practices, as well.

With multitasking an increasing fact of life for us all, it’s no surprise that machine tools continue to evolve into increasingly multifunction machine platforms, as well.
Let’s be honest, though, multifunction machines are not exactly new. For example, machines with processes that work together providing several functions, such as milling, turning, drilling, tapping, measurement, and EDM have been around for a number of years as requirements have changed.
I’ve also seen a number of interesting things on the exhibit floors at manufacturing trade shows, such as RAPID and IMTS, that employ traditional multifunctional capabilities, but have been most intrigued by a new emerging class of hybrid 3D printers that employ both additive manufacturing (AM) and subtractive (conventional machining) methods. Some of these innovative hybrid machines follow.

Wow, it’s still summer, but what a week for cloud-based CAD apps. First, Onshape for Android, and now this development from Spatial and Machine Research.
Spatial Corp., a provider of 3D software development toolkits announced that Machine Research, a software provider that helps manufacturers increase efficiency and profitability, has leveraged Spatial’s 3D InterOp and 3D ACIS to launch the first Machine Research app for manufacturers, providing them with the ability to view, measure, collaborate, and translate virtually any CAD file type to any other file type on a secured cloud-based platform. Customers also can manage projects, utilize a visual search engine to find legacy projects of similar geometry, and customize and standardize the quotation process across their organization.
