CAD & CNC Machine Training COMPUTER-AIDED-DESIGN (CAD)
Computer Aided Design (CAD) has almost totally eclipsed traditional drawing and drafting in design and manufacturing. CAD refers to powerful software which dramatically accelerates the design/manufacturing process and allows, even encourages, global collaboration.
CNC Machines read computer-aided-design (CAD) files which instruct the machine the milling pattern, including the tool path; where to move; and how fast to move when milling a material.
IYRS School of Composites Technology students spend approximately four weeks learning CAD software on the Rhino3D CAD software & platform. Students demonstrate their CAD proficiency by creating a virtual model of an object they will produce in the composites shop.
COMPUTER-AIDED-MANUFACTURING (CAM) & CNC MACHINE TRAINING
The other piece of this digital revolution is Computer Aided Manufacturing (CAM). There is a misguided belief that we don’t manufacture anything in the U.S. anymore. In fact, manufacturing is strong, but we are producing more with many fewer people. What makes this possible is CAM utilizing Computer Numerical Control (CNC) machinery.
Once IYRS Composite students have demonstrated CAD competence, they are introduced to CAM. The students will begin this by learning the rudiments of G code, the machine language for virtually all CNC machines. From there they will learn to use RhinoCam which is a software plugin operating in the Rhino CAD environment. This powerful software facilitates the generation of complicated machine operations and tool paths that are automatically converted to G code.
All of this knowledge allows an individual to “bring the virtual to life.” These digital skills are extremely valuable throughout our advanced manufacturing economy.

I have finished two weeks working in the boatyard at Barangay Población 1. We work 54-hour weeks: nine and a half hours per day from Monday to Friday and six and a half hours on Saturday. The heat is stifling and there isn’t a beach in sight. There are just stinking mud flats and twisted mangroves full of trash and debris. Though I am enjoying my time and am glad to be here, this is not a tropical working vacation and I am certainly not having a” blast.” Working all day in the beach-less tropical heat with a sub-par toilet situation does not fit my definition of the word. I have a blast when I am skiing or cosmic bowling or playing with a cat. But I’m not here to have a blast. I’m here to help. This isn’t about me. Well, it’s kind of about me. This is part of my schooling, so I am also here to learn. And when I think about the most important lessons I have come upon, not one of them has been learned whilst having a blast. To answer the question of what it is that I hope to learn, I must introduce you to Leo the boatbuilder.
Leo is a native of the Pinabacdao municipality. He stands five feet tall and is built like a power lifter. He is our master builder, subject matter expert on bangka construction, and the project’s ultimate authority on quality assurance. He can fix any screw-up, never loses his cool, and speaks no English other than about 20 words for tools and boat parts. After one day of working with Leo and talking to him through an interpreter, it became clear to me that anything I would learn from him would not come from him explaining anything to me.
I was watching him prepare a stem and keel to be joined together. He was making pencil lines with a less-than-straight edge and taking measurements with his finger and eyeballing the critical angles to be cut. My hand was twitching. It wanted to leap into my tool bag and give him my bevel gauge and sliding square. I held back. I asked him, through the interpreter, why the cuts went where he put them. Was a certain depth of cut based on the thickness of the keel? He replied,“That’s how the stem fits on.” Okay, but is that based on the size of the stem? And does a certain angle give the joint the maximum strength? “That’s so it fits together.” Thanks, Leo. You’ve been very helpful.
Then I remembered an exchange I had while I was learning Spanish. I asked a Dominican if it would be right to use the subjunctive mood in a certain sentence. She stared at me blankly. She explained that she had no idea. “Surely you know. You just used the subjunctive in that sentence explaining that you had no idea! Come on, you speak Spanish!” Then it occurred to me that she didn’t know what I was talking about because she was a native speaker. To her, the subjunctive and all of the other grammar rules came as native speaker’s intuition. Would you be able to explain the use of the subjunctive in English? Neither would I. But we would know if someone used it incorrectly. That is how I learned much of my Spanish. I heard enough native speakers talk and learned to imitate them and eventually it started to sound good to my ear.
That’s how it is with Leo. He’s a native speaker of the language of boat building and craftsmanship, and I am not. I have to watch how he works and imitate him until it becomes intuitive to my hand and eye. Or, as close to intuitive as it can get. I want to absorb that natural panache. To be fair, the boats we build back in Newport are way better than the boats here in every possible way. But that doesn’t matter. Even if I could build a perfect S-boat by myself with zero mistakes, I’ll never be a native speaker of the language. No matter how good I get, there will always be something to learn from guys like Leo. The naturals.
Stay tuned for next week. I’ll tell you all about how out-of-place my bevel gauge is, and about my awesome new boat building tool: the bolo.
Boatbuilding & Restoration student Will Aurigemma is spending his summer on internship in the Philippines. He will be in Tacloban City, which was hit by two category-5 typhoons (Yolanda and Ruby ) in 14 months. Fleets of wooden fishing boats were destroyed, and fishermen have been left without their main source of income. An international disaster relief organization called All Hands Volunteers is working with local builders to rebuild boats in the communities most affected by the storms. Will has joined their team as part of his IYRS summer internship. 06/30/15 Marine Mechanic Training: Turn Your Passion into a Career
Do you love boats? How about sailing, or just being around the water in general? Are you tired of meetings and cubicles & in need of a change of pace? Are you just looking to fix your own boat rather than pay someone else to? Do you want to work for Hinckley, Beneteau, a luxury superyacht or a large merchant vessel?
If you answered yes to any of these questions,
may be for you. marine mechanic training MARINE MECHANIC TRAINING (WHAT TO EXPECT)
Marine mechanic training is specialized
hands-on training for individuals who prefer to be active at work and seek to work with boats and yachts, on or around water. Many marine mechanics work on repair and service gasoline and diesel engines, as well as troubleshoot, repair and maintain: Steering & Propulsion Systems Engines & Motors Plumbing Systems Fuel Systems Electrical Systems Troubleshooting Mechanical Failures and Issue Diagnostic & Repair MARINE MECHANIC JOBS
The job market for marine mechanics goes well beyond recreational boating, though that certainly presents opportunity. Opportunities may exist in the following:
Marinas Boatyards / Shipyards Boat, Yacht & Ship Manufacturers Third Party Boating Parts or Products Company Mobile Mechanic Services Crew Onboard Superyachts or Larger Merchant Vessel or Commercial Vessel* “Freelance” Mechanic
*additional training and certifications required
According to the Bureau of Labor, demand for Motorboat Mechanics and Service Technicians is expected to increase 4.1%. Powerboat sales were up 7-8% in 2014 and are expected to increase another 5% in 2015, projects the National Marine Manufacturers Association.
MARINE MECHANIC CERTIFICATIONS
The American Boat & Yacht Council (ABYC) is widely considered the “gold standard certification” for the boating industry. In fact, many insurance companies prefer insuring companies who hire ABYC certified marine mechanics. ABYC offers the following certifications:
Electrical Marine Corrosion Marine Systems ABYC Standards Diesel Engine and Support Systems Gasoline Engine and Support Systems Composite Boat Building Refrigeration and A/C
IYRS Students sit for Marine Systems, Diesel, and Electrical Exams
