Post Processing | 3D printing presents challenges in workholding for finish machining
AM Business Manager,
Metal 3D printing can enable rapid, low cost iterations of new medical devices, since no tooling costs are involved. All devices need testing to uncover problems and develop solutions—allowing the product shape to change “for free” is a powerful advantage with Additive Manufacturing (AM). Other benefits flowing from AM besides enabling more complex geometry are improved accuracy with no component tolerance stack up, and a simplified supply chain with reduced part count.

Turning to an Adhesive for Lathe Workholding
“Adhesive cured by ultraviolet light is an option for securing parts for machining that could otherwise distort when traditional, mechanical clamping techniques are used.”

Aerospace engineering firm JJ Churchill has announced it has reduced its tooling costs by 5% with a 50% reduction in the number of machining operations on a specific critical part.
This has been achieved with Blue Photon technology which is marketed in the UK and Europe by NCMT Limited.
This technology is applied to a titanium aluminide aerofoil blade component which is an extremely difficult material to fixture and machine. Blue Photon fixes the component to the tool with an adhesive, which cured under UV light, is strong enough for the most rigorous machining techniques including 5-axis CNC. The process is a replacement for encapsulation, providing reduced fixture complexity. Read the rest of this entry »

Precision Grinding and Manufacturing uses an atypical means to fixture thin parts that are prone to flexing when conventional workholding clamps are used: adhesive cured by UV light. -By Derek Korn
Sometimes, the trickiest aspect of developing an effective machining process is figuring out how best to fixture the part. This can be especially challenging for castings and other workpieces that are relatively thin, because those parts are prone to flexing when conventional mechanical clamps (and even vacuum chucks in some cases) are used. Operators must take care not to distort such parts while tightening clamps, otherwise the parts will spring back to their natural state once the clamps are removed after machining. Vibration can also be an issue for parts like these if they aren’t rigidly fixtured, meaning a quality surface finish might be tough to achieve and cutting parameters might have to be dialed back, extending cycle times. Finding a way to effectively fixture complex, contoured parts can be just as difficult. Read the rest of this entry »

Productive Times: Stick With It
By Kip Hanson – Published September 1, 2015
Let’s say you want to machine your initials on your favorite Hummel figurine or cut the likeness of the school mascot on your daughter’s Little League helmet. How are you going to grip them? A conventional way to grip fragile, difficult-to-hold workpieces is to encapsulate them in some sort of potting compound, a time-consuming and wasteful process.
Rather than mix up a tub of two-part epoxy, consider photo-activated adhesive workholding (PAAW). Read the rest of this entry »

Productive Times: Bonded By Light

Urschel Laboratories Inc. manufactures industrial equipment to slice, dice, shred and mill virtually any food product.
According to Bill Monroe, senior manufacturing engineer for Urschel, the company machines parts for the food processors at its only manufacturing facility, located in Urschel’s 350,000-sq.-ft. headquarters. Urschel produces many of these workpieces in its two foundries. “We have a no-bake foundry and an investment foundry,” Monroe said.
As part of a major new project that Urschel, Chesterton, Ind., started late last year, Monroe needed to hold a 300-series stainless steel billet that was convex on one side and then access five sides when machining it on a 5-axis machine. Read the rest of this entry »

Adhesive Workholding Allows Turbine Blades To Be Ground In One Hit
Technique offers the possibility of automated production
A new method for securing a turbine blade prior to machining by gluing one side of its aerofoil to a fixture, rather than using mechanical clamping, allows the root and tip to be ground in one operation. Traditionally, due to clamp interference, at least two operations are required on conventional CNC grinders to machine the fir-tree and wedge face on the root as well as the shroud end features at the tip.
The one-hit manufacturing process is not only faster, but also eliminates work-in-progress and the risk of introducing inaccuracy due to repeated refixturing. The technique is being developed in the UK by NCMT, which sells Makino’s VIPER grinding platforms across Europe. Since May 2015, the company has also been European agent for the patented Blue Photon photo-activated adhesive workholding system from the USA. Read the rest of this entry »
