ECM…New Paths in Part Production

Electro-chemical machining offers manufacturers a smart alternative to conventional processes

Simon Popecki
ECM Applications
Engineer EMAG LLC

To understand electro-chemical machining (ECM) it’s best to start by understanding it’s not electrical discharge machining (EDM).  These technologies for non-contact machining are routinely confused, but there are distinct differences – EDM vaporizes metal and ECM erodes it via electrolysis- which is less violent.  For our purposes here, the key differences are three: While current is passed between an electrode and workpiece in both methods, in ECM there is no spark – ECM uses a conductive electrolyte while EDM uses a dielectric, ECM has virtually no tool wear, and in ECM there is no HAZ (heat affected zone) like there is in EDM. This results in a part with no burrs, and the ECM process has potential for exceptional surface finishes even on extremely hard-to-machine materials, such as those found in medical, aerospace and firearms manufacturing.  Medical, auto, and firearms take advantage of another aspect of ECM which has significant merit: namely, the ability to produce contours and pockets deep inside parts that would otherwise be difficult or even impossible to manufacture with conventional chip cutting methods. The machining force in ECM is just the pressure of the electrolyte which allows ECM to produce features like high aspect ratio holes in conductive materials of any hardness.

As material is dissolved in the electrolyte, it is evacuated from the work area and the tool imprints its geometry upon the workpiece.  ECM can produce tight contours on everything from airfoils to the grooves of a rifle barrel with exceptionally tight tolerances. In the latter, rifle grooves can be cut to a depth of ± 2.5 micrometers.

It was turbine blade production that sparked the development of ECM, in the then Soviet Union after WWII.  Much of the ECM expertise today has roots in aerospace. In the production of turbine blades for example, ECM produces burr free, HAZ-free parts via PECM – an advanced ECM process combining the oscillation of the tool with pulsed current to create a superior surface finish on Inconel and other hard materials.

Today, electric mobility is emerging as another ideal application for the ECM technology.  Thin-walled parts, those with many complex features can now be formed very efficiently.  ECM, is commonly thought to be limited to hard aerospace materials but that is not the case.

Since an ECM machine like the EMAG CI platform serves as a base to provide the structure, intelligent power application, and precise electrolyte control to the fixture – sinking, drilling, broaching and deburring can all occur on one machine based on the fixture configuration. By changing the fixture and tooling, the machine can be converted to a completely different machining task. If the part you deburr with ECM today stops selling tomorrow, you can re-fixture the machine for a different part to maximize productivity.

In the production of gun barrels, the traditional methods are cut rifling, buttoning and hammer forging.  ECM has distinct advantages over these methods – particularly output, consistency, precision, low tooling cost, and the elimination of post rifling processes. Stress relieving or straightening can be eliminated with ECM. The ECM process can rifle profiled barrels or blanks, and Inconel barrels are just as easy as ordnance steel.  Unlike buttoning, ECM can quickly rifle a barrel with no distortion during the process. This is valuable in the production of air guns and composite reinforced barrels, for example, where the thin-walled barrel is more susceptible to distortion, which leads to inconsistency and ultimately a compromise in accuracy.

ECM rifling is best suited for high production runs with minimal variation, and here again ECM is showing substantial value.  In competitive shooting, where match grade barrels are the minimum standard, and gain twist and special groove profiles are prominent, the effectiveness of the ECM process is distinguished.  On ECM machines today, a hunting rifle barrel and a military cannon barrel can potentially be rifled on the same machine. Caliber change-overs can be done in minutes.

In the general manufacturing world, ECM is popular for various purposes such as crown gear manufacturing and the process is now finding its place in the booming markets of e-bikes, scooters, hybrids, and electric cars.  When complex geometries and contours are a necessity, the efficiency of the ECM process is a proven winner.

For higher production runs, it is possible to stack multiple workpieces without risking excessive heat transfer or distortion.

Increasing Static Friction with Laser

By Gerhard Flores, Manager of Technology Development and Intellectual Property
Gehring, Farmington Hills, Michigan

Note to editor: Information in this article was derived from the presentation given by Gerhard Flores at AGMA’s Fall Technical Meeting between September 24th and 26th in Chicago.

Gerhard Flores discusses the need for flat and curved surfaces with the functionality of high static friction for force-fitted nonslip power transmissions. This need is especially true for con rod and cam structuring for high torque resistance or front face connections of sprockets, gears or cam shaft adjustments. He details that expensive solutions like diamond layers, coatings or form fitting design are being substituted. Instead, innovative manufacturing is now performed by a modified laser process with defined exposed micro structures. The prerequisite for high friction is exposed micro melting burrs of smaller micrometer height with martensitic material structures. As a result, high static friction surfaces can be produced economically with repeatability of small tolerances in high-volume productions.

Increasing Static Friction with Laser With Gerhard FloresProduction of surfaces that generate static frictional connections with the counterpart are increasingly realized with a modified laser beam. The contact surfaces actuated by adherence are laid out with topographies that assure the functioning of work pieces and they can be produced in a cost-efficient way. The requirements of the connections include loads by torques and shearing forces. The system is kept is kept in a state of adhesive friction during the different operational conditions and does not allow any relative movement of the contact areas.

The principal feature of the adhesive system was revealed in a stress test. In it, hardened and structured contact surfaces are loaded against non-structured and unhardened ones with an axial force of 80 kN over 60 seconds for a twist angle of 4 degrees. The course of torque was indicated as target value. The contact areas (di= 15 m, da= 30 mm) were dry and free of grease. At the junction of adhesive and sliding friction, there is a maximum of adhesive value.

Using the adhesive friction bench or the functional aggregate, the effects of structure can be evaluated. Every structure that increases adhesive friction is characterized by a raised profile contour that has influence on the counter body. Next, manifold micro form profiles are produced to absorb shearing forces. Furthermore, the micro form profiles result in a frictional connection with high adhesive friction value. Due to the thermal effect of the laser beam, hardness is generated due to the short heating time.

There are significant differences in the laser structured adhesive friction surfaces of cams, connecting rods, front face connections and pre-treated substrate surfaces. Cam topographies can be raised with low profile elevations and without deepening. Material melts evenly. The structure lines of connecting rods are equidistant superposed. Both cam shafts and connecting rods can absorb torque of shaft hub joints. Between the structures of front face connections, there are often deepenings caused by material transfer. Lastly, pre-treated substrate surfaces display a squamous structure with micro recesses and are suitable to join layer materials to substrates.

Laser structuring of adhesive friction surfaces in rigid friction type connections can substitute positive locking design connections or other expensive friction type connections like diamond interlayers. The achievable adhesive value depends on the depth of the height, the profile shape of the laser structured roughness profile, the arrangement of the structure density, the martensitic properties of lasered materials, the normal force and whether the lubricant is embedded in the contact surfaces or not.

Different connections with torsional strength have different cylindrical contact surfaces. A shrinking connection with the laser structured inner surface of the cam and the shaft, enables the cost effective built cam shaft in serial production. In the case of the clamping connection shaft and the hub, the laser structured contact surfaces are engaged by clamping. This replaces the costly alternative of positive connections. In this way, pin or fitting connections can be replaced by friction type contact surfaces with high adhesive friction generated by the laser structured process.

Another category is the frictional connections of plain functional surfaces for the transmission of shearing forces of torques. The laser structured front surface, often designed with an alignment element replaces cost-intensive solutions like form-locked joint coupling with frontal tooling or inserted diamond or SiC interlayers as slices for the increase of the friction value. Applications related to the combustion engine like pinion, cam shaft adjuster, ball bearing or related to the chassis frame are becoming frequently demanded alternatives to the expensive solutions with slices and interlayers.

Laser structuring of the connecting rods is realized by means of the crank pin, which joins the connecting rod and the crankshaft. The design of the bearing consists of the rod eye, the bearing shell and the crank pin of the crankshaft. There is a rotational relative movement between the crank pin and the inner side of the bearing shell. The joint is laid out as a sliding bearing and works with low friction. However, there is no movement allowed between the outer side of the bearing shell and the connecting rod bore. Here, a sufficient high adhesion is required to absorb the frictions within the sliding bearing. Next, a frictional connection is necessary to deliver the suitable torque strength by means of the elevated topography of the connecting rod and the resulting adhesion.

For the process of laser structuring, a solid body laser with scanning optics is used. The two beam sources are arranged above the connecting rod eye laterally, the connecting rod bore. The beam sources work simultaneously and structure each of the two areas with the connecting rod bore. In each unit, the pulsed beam is guided by the galvanometer scanners with two galvanometer mirrors each. There is no mechanically actuated displacement or positioning of the beam and the focal movement is carried out quickly, line by line, with the highest precision and simultaneously by the movable optics of the integrated scanning heads.

The laser structuring of cams takes place after the shaft and cams are machined as single parts and are assembled by thermal friction type connected processes. In order to achieve sufficient torque strength of the cams, their bores are structured for enhanced adhesion.

Friction type connections are applied in several sectors of mechanical engineering and vehicle design for the transmission of shearing forces and torque. Frontal face connections with plain contact surfaces are laser structured in serial production. Cam shaft adjuster, chain pinions or gears are the focus of the central valve of Schaeffler with the cam shaft in serial production. This valuable technology reduces carbon dioxide emissions. By laser structuring of the main bearing, a high torsion strength of the bearing shell can be realized by the roughly structured areas of a cylindrical type connection as well as heat transfer by the smooth unstructured areas.

In conclusion, the advantage of laser structuring with integrated scanning is that the structuring segments on curved and plain surfaces can be freely dimensioned and positioned. In addition, the structure data and the tolerances of the different surface values can be adjusted by the beam parameter. The structuring process is completely automatable and can be integrated in a production line. Laser structuring allows an increase of static friction up to 5 times. Compared with diamond interlayers, the costs and number of parts is significantly lower.

Centrisys/CNP Announces Exclusive U.S. Distributorship for the Passavant® hydrograv® adapt System

Passavant hydrograv adapt SystemCentrisys/CNP (Kenosha, WI), a leader in decanter centrifuge technology and systems for nutrient recovery and sludge optimization, has announced their exclusive distributorship for the Passavant hydrograv adapt System in North America (U.S. patent pending).

Unlike fixed inlet structures for secondary clarifiers, the Passavant hydrograv adapt System consistently and continuously adjusts to current loading in a clarifier. If the loads are low, the hydrograv adapt automatically shifts the inlet elevation and opening height to a low position, introducing the mixed liquor below the sludge blanket. As the loads increase, the hydrograv adapt system shifts itself to a higher elevation and opening height, ensuring ideal hydraulic conditions for the operation of the secondary clarifiers and avoiding sludge overflow.

Benefits of the Passavant hydrograv adapt System include improved process stability of secondary clarification, a reduction of effluent suspended solids to usually less than 3 mg/L, improved particulate phosphorus removal, improved clarification capacity from hydraulic optimization and overall low maintenance requirements.

At WEFTEC 2018, Dr. Martin Armbruster, the Managing Director and founder of hydrograv GmbH and the inventor of the hydrograv adapt system, will co-present on the topic of “Stress Testing of a Secondary Clarifier with an Adaptive Inlet Structure.” His expertise in the field of clarifier CFD simulation includes optimization and practical engineering for more than 1,000 clarifiers in 200+ treatment plants worldwide. His experience in improving hydraulic efficiency of water management systems is based on 500+ hydrograv® with CFD simulations installations. The seminar will take place on Wednesday, October 3 at 1:50 p.m. in room 239.
