Machine Shop Utilizes Forging Press To Reduce Costs Of Titanium Parts
To provide complicated titanium parts extra price-successfully, machine shops are more and more incorporating advanced forging gear to complement their existing CNC capabilities to create near-net-shaped parts that only require minimal machining. In some circumstances, the forging process is so exact that no additional machining is required.
There are vital benefits to incorporate forging in a machine shop’s repertoire. If you loved this short article and you would like to obtain additional facts about titanium wire - Repo.getmonero.org - kindly pay a visit to the webpage. With current advances within the controls and automation of hydraulic forging presses, precision titanium elements may be solid to extremely tight tolerances, and at comparatively high quantity. Forging also significantly lowers titanium input prices by as a lot as 50%.
To forge titanium to precise specifications, however, machine retailers require the best equipment with exceedingly tight control of the production parameters. Fortunately, advances in hydraulic press design, controls and automation are serving to to optimize part high quality, manufacturing and worth.
To price-successfully produce massive, complex titanium parts, Pennsylvania-based mostly FPD Company, a machine store that produces aerospace and medical components, determined to put money into a novel new customized press able to better control with higher tonnage.
"We wanted to extend our solid parts envelope, and that required a larger press with more refined controls for the titanium parts. We already had a 2,500-ton press, which is relatively small for titanium. At the same time, we needed to improve control, high quality and cycle times," stated Jeff Speicher, General Manager of FPD.
To achieve its production goals, FPD partnered with Erie Press Systems, a producer of mechanical forge presses and individually engineered hydraulic presses since 1895 that's now a part of the largest forging gear supplier in North America: Ajax-CECO-Erie Press.

Although Erie Press designed, engineered and constructed the system, FPD offered vital input on the design necessities. The outcome was a customized excessive-velocity hydraulic press able to producing 3,000 tons at a completely managed, programmable velocity and cargo profile by full journey.
"The custom press, along with our engineering and tooling, permits us to carry extremely tight tolerances persistently when creating titanium elements for the aerospace and medical device industries," Speicher mentioned. "With the fitting tools, the forgings are extremely consistent, and we will produce near-net shapes that require minimal to no machining. If a component wants additional machining for holes, bores, and other secondary features, we will try this as well."

Precise Control of Forge Stroke, Force
In accordance with Speicher, the Erie Press forging gear is designed with a singular servo hydraulic system that permits greater control of the forging stroke and applied pressure.
The press control modulates the servo proportional accumulator discharge valves to take care of the programmed velocity regardless of the load, guaranteeing consistent forging performance. This association supplies flexibility to forge elements across a large velocity range not doable with a mechanically adjusted accumulator discharge charge configuration.
For some part geometries, the deformation rate of the titanium might require variable velocity profiles throughout the forming course of. Altering the deformation price enables FPD to achieve improved die life whereas creating better detail by filling the die cavity webs and corners later in the stroke.
In keeping with Speicher, the servo-hydraulic system permits extremely excessive decision in defining those parameters. Furthermore, the press position controller publishes (to FPD’s plant server) a high-velocity plot or digital signature corresponding with every part’s forging cycle for historic information and reference.
FPD can even management the press to strike the part at a specific pressure or to a pre-outlined tonnage restrict. In addition, the press can stroke to a programmed position inside a positional accuracy of less than .01".
Erie Press’s Human-Machine Interface (HMI) permits operators to see how the press functions and anticipate the way it should be performing. That is achieved with dynamic animated models and schematics, dwell trending and diagrams.
Ajax-CECO-Erie Press included a person-pleasant, graphics-primarily based HMI into the design that helps operators monitor what is going on to allow them to efficiently troubleshoot and promptly get the equipment back online.Ajax-CECO-Erie Press
The HMI is a software program software that graphically presents data to operators in regards to the state of assorted processes in a format that looks like the actual machine or show panel. The data will be accessed domestically (on the machine) or remotely (throughout the plant or offsite) via Pc, laptop or smartphone.
"Erie Press included a really person-pleasant, titanium rod graphics-primarily based HMI into the design that may stroll even someone unfamiliar with the forging course of through it step-by-step," mentioned Speicher, adding that the forging press manufacturer’s HMI system is a digital "digital twin" of the actual machine because it features.
"The press has sensors that monitor the ram place, pump output, valve positions, etc. and all these parameters are monitored in a digital representation of the press. With the HMI, the operator sees how the machine is performing in actual-time,."
The HMI additionally helps operators monitor what is going on with sufficient perception to successfully troubleshoot and promptly get the equipment back online when required.
For instance, operators can shortly "drill down" from a top-level animated schematic to review the efficiency of specific elements, akin to valves and pumps, and locate info on half numbers and wiring schemes.
Up-to-date PDF technical paperwork and the schematics of each component on the machine are additionally searchable and may be quickly displayed as needed.
The Erie Press forging gear incorporates automation that allows the operator to vary-out sizzling dies in less than ten minutes. A forging change-over is totally hands-off, requiring only inputs to the HMI. Titanium billet and workpieces are pre-heated in an electric furnace, whereas the tooling is pre-heated offline.
The operator, working behind an interlock gate system for security, uses a joystick to transfer the tooling into the press, which is hydraulicly clamped into place. A barcode is scanned on the production router, which calls up a component-particular forging program within the controller.
FPD worked with Erie Press to include security options akin to preventing this system from executing if the bar codes of the toolsets and elements don't match the router, and a security stroke the operator should execute earlier than proceeding to automatic mode.
"Because we produce a number of quick runs, we are able to set up a number of instances a day and titanium tubing tube this offers us super production capacity," said Speicher.
Unit value can lower considerably over a hog-out half attributable to utilizing much less input material, with the help of a 3,000-ton press like that from Ajax-CECO-Erie Press.Ajax-CECO-Erie Press
Extending Longevity, Lowering Cost
Controlling stroke pace has also helped to prolong tool life.
"With the hydraulic servo control, the operator can range the press’s stroke velocity with way more control, which prolongs device life. In keeping with our inner statistics, the brand new press has extended tool life by about 50%," stated Speicher.
There are also significant value savings versus the typical machining strategy.
"Depending on the part geometry, we will usually scale back unit value within the 30% to 50% range over a hog-out half [machined from bar, plate or billet]. That is because of utilizing less enter material - and titanium may be very expensive," Speicher stated.
