Machinist’s Corner: Apprenticeships wanted
Lately, I haven't been hearing much about machinist apprenticeship programs. I have been hearing about vo-tech schools, as well as job shops hiring people off the street to just push buttons. Do apprenticeship programs still exist in the U.S.? The answer is "yes!"
Get With The Program: Barrel-cutter CAM strategies
Barrel cutters are applied for specialized milling applications, and recent advancements in CAM software expand the use of these tools. Geometrically, a barrel cutter has a large cutting radius on its side that closely matches the curvature of a part's surface and allows a large step-over between passes.
Manufacturers learn to invest in training
Every parts manufacturer, regardless of size, has some sort of training program, and programs are nearly as varied as the companies themselves. Whether it's something as simple as handing out a pamphlet about company policy or as involved as an apprenticeship program, it's just a given: Where there are employees, there is training.
Terms of the trade for surface roughness measurement
As the plans for more and more machined metal parts include numerical surface finish specifications, the need diminishes to visually qualify that a part has, for example, "a mirror finish with no burrs" or to have the machinist with the finest touch scratch the surface with his fingernail to make sure it's "matte and rough."
Challenges in the micro-EDM world
Say "EDM" and most manufacturing folks think mold, tool and die work. Yet sinker, wire and hole-popping EDMs are often employed in conjunction with, or as alternatives to, traditional part-making processes, such as milling and turning.
Benefits of micromachining with lasers
Lasers are good for far more than slicing sheet metal and defending against alien space invaders. Without them, many of today's high-tech products would be impossible to manufacture. Microfluidic devices, integrated circuits, medical stents and catheters, automotive fuel injector nozzles are all drilled, milled, surface-textured and ablated via laser micromachining.
Growing demand for microparts challenges suppliers, users
Ever machined parts so small that they not only fit on a penny but can sit on old Abe's nose? Cutting parts and part features in this Tom Thumb world often comes with Titanic-sized challenges, such as unexpected cutting tool breakage, deburring parts the size of typical burrs and machine tool spindles speeds that come up short.
A twin-turret approach to machine tool stiffness, stability
Two rotary axes beat 2' of stacked linear axes. That's the idea behind the new Twin Turret Generator (TTG) machine tools from Cranfield Precision. According to the company, the TTG machine offers a stiff and thermally stable design that improves machining precision and repeatability.
The contours of a robotic 3D-printing platform
Arevo Labs hopes its new RAMP leads to better 3D-printed componets for the defense and aerospace industries. Arevo touts RAMP (Robot-based Additive Manufacturing Platform) as the first system of its kind optimized for 3D printing of composite thermoplastic parts. The system includes a 6-axis robot arm and end-effector hardware for deposition.
Moving large, complex parts calls for specialized equipment
Until I started working for Mitsubishi Hitachi Power Systems Americas, lifting parts was never a consideration in daily production. Previously, the parts I dealt with were small, usually never larger than a dinner plate.
Lead Angle: Invaluable resources: Turning Performance
Early in my stint here, I called Alan Baker, founder of toolmaker A.B. Tools Inc., in connection with an article I was writing about thread milling small-diameter holes. I started the interview with a general question about available thread mills sizes for these applications and was encouraged to first gather that information from Machinery's Handbook and then call him back.
