Today I saw a demonstration of SolidCAM’s newest version of its iMachining technology. The co-hosts of the presentation were Shaun Mymudes, COO, North America and Ken Merritt, senior application engineer.
After a little SolidCAM iMachining theory, the science of cutting angle, and how it’s different from the competition, a live demonstration via webcam began with new iMachining software controlling a Hurco VMX42 HSi machining center. A tool running at 10,000 RPM and traveling at between 85-200 inches per minute cut and finished a pocketed part of 1018 steel in pretty short order.
Owing to iMachining’s unique tool motion control algorithms and variable cutting angle, the presenters said (and showed) significant improvement in cycle time efficiency/time savings (in this case, more than 70%), as well as reduced tool wear.
After the live demo, it was time to see some of the features and capabilities of the software.
Autodesk President and CEO, Carl Bass, led a conversation about “Engineering the Future” for the manufacturing industry at Develop3D LIVE 2013.
In a keynote address, Bass demonstrated how a series of major technology trends are shaping the way product designers and engineers work, and how these trends paved the way for Autodesk to create its cloud-based design platform Autodesk 360, which has been accessed by nearly 15 million users since September 2011.
Additionally, Bass announced that pricing for Autodesk Fusion 360, Autodesk’s comprehensive cloud-based 3D CAD offering, will range from $25 to $200 per user, per month. Originally unveiled at Autodesk University 2012, the cloud technology behind Autodesk Fusion 360 offers universal access where design data is the center of the design process. It also supports an open design environment, allowing designers to incorporate and modify CAD data from virtually any source and share it.
Carl discusses the Cloud and how it is transforming design:
In the following video, Carl discusses how Autodesk is solving tough design problems with Fusion 360, and provides examples of how Fusion 360 provides designers and engineers with clear choices on not only what they want to use, but also how they can buy it, and what it costs.
This is interesting news because I’m about to go hands-on with Autodesk Fusion 360. I’ll tell you how it goes.
Like many people, if not most, spring is my favorite time of the year. The days are longer, the weather is warmer, foliage is coming back to life, and it’s the season for FIRST Robotics Competition (FRC) all over the country. Eligible participants are male and female high school students — grades 9-12; ages 14-18.
For those unfamiliar with the event, every team is given a standard parts list and kit from which to build their robot that consists of mechanical, electrical, electronic, and software components. This, along with rigorous inspection for compliance with the strict rules and specifications before competition ensures that all teams literally compete on a level playing field.
A FIRST team working on their robot, preparing for competition
I was a volunteer at this year’s Colorado Regional FRC event. My official title was Field Repair/Reset, but in actuality I was a scorekeeper. Once the action starts, it’s non-stop and pretty heated until the competition is done for the day. Between the robots, teams, and fans in the stands, the volume level also remains pretty high throughout the day. A lot of excitement and great fun for me.
The game changes every year and this year’s was especially challenging. It involves team-built robots picking up and shooting Frisbees into target goal at varying heights. In addition, there is also a segment of the event that has the robots climb tubular pyramids — the higher, the more points. For safety, if a robot ascends above a certain height, it must be belayed back to the ground with climbing rope and special hardware.
There are also two different timed modes for competition — autonomous and teleops. The first 15 seconds are autonomous where the robot must find the target goals on its own and attempt to fling Frisbees into them. The teleops portion of the competition has the robots “driven” by team operators with computers and joysticks.
I wish my tools were this well organized . . . team from Minnesota’s tool crib
The FIRST events are always well organized, well attended, and well worth the time of everybody involved — participants, volunteers, teachers, parents, mentors, and sponsors. The FIRST event always leaves me with a good feeling about the promise of the future of engineering in the hands, minds, and hearts of those who will create the future.
On a weekly basis I review hundreds of press releases relating to (more or less) CAD, CAM, CAE, and related software and hardware products. With most of them it is immediately apparent whether they merit publication, are overt sales pitches, or new rehashes of old news. Not always, but often, my interest gets sparked by the headline, such as, 3D Printing Inspires New Working Style in CAD/CAM Software Industry. Interesting stuff, right? The headline was pretty catchy, although it didn’t mention a specific company name. In spite of that, I read through the press release once, twice, three times, and still had trouble comprehending what was trying to be said.
Well, the company is Chinese software developer, ZWSOFT, and what they are trying to get across is the new Print3D function in ZW3D 2013 for leveraging 3D printing. The company doesn’t tell you how to do it and the 3D printing capability isn’t specifically mentioned in its 56-page “What’s New in ZW3D 2013” document. In fact, if this press release had not come out, there is no way I (or prospective customers) would even know it’s there. I tend to think it’s buried in some obscure place that will really take some digging to find.
3D printing is mentioned in online product literature under Reverse Engineering in the following context (and accompanying graphic):
Work with STL, point cloud, and scan data to build surfaces and 3D models
Prepare models for CNC machining by refining meshes, building surfaces, and repairing gaps
Support 3D printers
I’m no marketing guy, but if you’re going to push a new capability, wouldn’t you give it little more prominence?
I’ll download a trial version of ZW3D 2013 and see what and where the 3D printing capabilities really are.
Beyond that, the only reference I could find with regard to ZW3D’s 3D printing ability was an event last year when personal manufacturer Ponoko teamed up with ZW3D and 3D model library GrabCAD to 3D print the winners of its Holiday Design Challenge.
So another MCAD company enters the market with this year’s “must have” capability – 3D printing – which is fine. I guess the more, the merrier. What I more interesting is a rumor I’ve heard from more than one source that another Chinese company may soon market a 3D printer in the $300-$500 range and PLA and/or ABS consumables for $10-$20 a spool.
While it is possible, I still maintain that 3D printing isn’t suited for everything or everybody. While there have been some impressive results, many of the parts I have seen produced on the so-called “low end” machines are analogous to dot matrix output when 2D printers came on the market. Like many technologies, just because “everybody’s doin’ it,” doesn’t necessarily mean that everybody should be doing it.
