Adjustable V Dies Enable Press-Brake Bending of Thick Plate
Exacta adjustable V dies, introduced by Wilson Tool Intl., allow fabricators to adjust the width of the V-opening from 1 to 18 in., in 1-in. increments, eliminating the need to purchase multiple dies with different openings. A single operator can adjust the opening as needed by moving the side blocks and then locking them into position. This greatly reduces changeover time and improves productivity, say company officials. The die assembly can be configured to remain on the press permanently and function as a standard die holder, further reducing the amount of time operators spend on setups.
Exacta adjustable V dies can withstand as much as 200 tons/ft. They are induction hardened and include hard chrome rollers to help reduce the tonnage required by as much as 20 percent. The chrome rollers can be replaced onsite as necessary, minimizing maintenance costs.
Fiber Lasers Still Attracting Attention
Mazak Optonics demonstrated its Optiplex 3015 4-kW fiber-laser cutting machine at its FABTECH booth. Compared to conventional laser-processing machines, the system reportedly increases the productivity of thin worksheet cutting with impressive accuracy and cuts cold-rolled steel to ¾ in. thick. The Optiplex 3015 Fiber also processes reflective materials with greater thicknesses and at greater speeds than its CO2 counterpart. The machine uses the firm’s new PreView 2 CNC control, which automatically determines the required processing conditions for the material prior to cutting.
Also new from Mazak Optonics is the availability of its Super-Turbo-X Champion with a 2.5-kW resonator. Built on the firm’s hybrid platform, the machine boasts a 1786-lb.workpiece capacity for sheets as thick as 0.87 in.
Better Nesting Slashes Cycle Times, Extends Consumable Life
SigmaTek Systems showcased its latest release of SigmaNest—Version 10—which, says company president and CEO Ben TerreBlanche, employs sophisticated heuristics and advanced algorithms to optimize part yield, maximize material usage, accelerate machine cycle time and produce the highest quality parts.
“Improved cutter-path planning reduces machine cutting-cycle time and consumable wear, extending tool life,” says TerreBlanche. New functionality includes Bolt Hole Quality (BHQ) technology, designed specifically for plasma-cutting machines to improve edge quality, by addressing inherent material melting issues. By tightly controlling this cutting process, BHQ reportedly optimizes hole quality and eliminates clean-up or rework.
Other SigmaNest 10 enhancements, as explained by product manager James Lindsey, include tight integration with MRP and other manufacturing and business systems, to catalog material remnants for future job runs; and SolidWorks Enterprise PDM integration.
Water Mist Makes for Cool Laser Cutting
Trumpf debuted the TruLaser 5030 cutting machine at FABTECH outfitted with a 5-kW solid-state TruDisk 5001 resonator, capable of cutting mild steel to 1 in. thick and nonferrous alloys to 0.4 in.
Also introduced at the show was the new CoolLine option for 2D laser-cutting machines, which sends a water mist toward the workpiece during cutting to cool the material. CoolLine, which includes a specially designed cutting head, varying nozzles and a water supply tank, allows fabricators to achieve higher quality cuts with smaller contours or greater complexity, and the ability to nest parts more closely together, according to Trumpf officials.
While processing, the CoolLine nozzle directs a water mist around the laser beam as it reaches the workpiece. In doing so, it reduces the amount of heat transferred in the immediate cutting zone and achieves contours that would otherwise be difficult or impossible to process. With this new option the user can cut small sidewalls and difficult geometries more efficiently, especially in thick material. It also achieves a considerable increase in process reliability when laser processing low-grade material or material of varying composition.
Multiprocess Weld Power
Esab Welding & Cutting Products introduced FABTECH attendees to Warrior, a new multiprocess welding-power source and wire feeder designed for general fabrication and for the shipbuilding, railcar, energy generation and other industries. Capable of providing power for the GMAW (mig), FCAW (flux-cored), SMAW (stick) and GTAW (tig) processes, as well as arc gouging, Warrior is rated to 500 A at 60-percent duty cycle.
Designed with input from welders, Warrior carbon-arc gouges with electrodes to 3⁄8-in. dia., welds with solid and flux-cored wires from 0.030- to 5⁄64-in. dia., and offers a full range of SMAW capabilities with excellent 7018 and 6010 performance. Its user-friendly design places all controls on the front panel, including the power switch, and knobs are designed for use when wearing welding gloves.
The Warrior Feed 304 wire feeder features a high-torque four-roll drive, which reportedly gives superior feed even with long GMAW guns.
Better Beveling When Plasma-Arc Cutting
Hypertherm announced the release of new edge-profiling technology designed to help fabricators more easily achieve accurate bevel cuts during automated plasma-arc cutting. Its new True Bevel technology includes factory-tested mild-steel cutting-parameter charts for all Hypertherm HyPerformance HPRXD plasma systems.
“These charts contain meticulously developed parameters to significantly reduce the amount of time and effort required to produce quality bevels using plasma,” says Hypertherm engineer Aaron Brandt. “We also know that most fabricators spend a considerable amount of time setting up their systems (for bevel cutting) through trial and error, and even then the outcome is inconsistent. True Bevel enables fabricators to perform accurate and consistent bevels without that lengthy setup time.”
In addition to True Bevel, Hypertherm announced several other advancements to its HyPerformance HPRXD product line, including new HDi technology that delivers optimum performance on thin (less than ¼ in. thick) stainless steel. Additionally, pierce performance on thick stainless has been significantly improved, say company officials, thanks to patented PowerPierce technology and a new controlled-motion pierce process that enables piercing on stainless as thick as 4 in.
Scalable, Flexible Shop-Floor Data-Collection System
From Wintriss comes ShopFloorConnect factory-reporting software and hardware, designed to automatically collect production data that is timely, accurate and unbiased. The software package comes factory-configured to talk to the ShopFloorConnect Machine Interface over an existing Ethernet. It tracks machine uptime, downtime, the reasons for downtime, production rate and piece-part counts (when applicable). It then displays real-time factory status in your web browser, and enables the creation of customizable reports—no special client software is required.
Using the scheduling interface in ShopFloorConnect, an engineer can create a queue of jobs to run in each machine. He then can either import a schedule from existing ERP software, or use ShopFloorConnect’s web-browser interface to select the appropriate jobs and the quantity of parts required.
The program predicts the completion time/date for each job in the queue with an algorithm that analyzes real-time and historical changeover and production data. And, when computing overall equipment effectiveness (OEE), rather than use a single ideal performance rating for each machine, ShopFloorConnect applies a specific ideal rate for each job segment/machine combination.
In applications where a machine must make more than one cycle to produce a part, Shop-FloorConnect automatically divides the ideal rate by the number of cycles required to make the part. It keeps a running total of the actual parts produced by the machine, and the number of parts that could have been produced according to the ideal rates and multipliers.
