Flexibility is an attribute any job shop seeks when investing in a machine tool. One OEM has developed technology that allows bevel gears to be hobbed on two of its turn-mill centers, eliminating setups on other machines, increasing throughput and reducing work cycle times.

After deciding to manufacture bevel gears for its own purposes in-house, Index developed a “gear hobbing package” that transforms its R200 and R300 turn-mill centers into gear cutting machines. This technology is now being made available as an option for new machines and also as a retrofit for those who have already invested U Drill Inserts in the R series. The package will be offered on additional machines in the coming months.

According to Dr.-Ing. Volker Sellmeier, head of technology development at Index-Werke GmbH & Co. KG Hahn & Tessky in Esslingen, Germany, the gear hobbing technology package consists of four elements. The first, of course, involves the R series machines themselves, which feature two motorized milling spindles that perform machining functions in two independent subsystems, including five-axis machining. Both roughing and detail operations can be performed simultaneously on the machines, which have been designed to deliver optimal stiffness, thermal and dynamic stability, and vibration-damping characteristics.

The second element involves the four cutter heads specially developed by Index for this operation. These four heads are required to machine bevel gear sets consisting of a pinion and a wheel. The third component of the package is the OEM‘s bevel gear control cycle that allows users to operate the R200 and R300 machines exactly as they would a conventional bevel gear cutting machine. Its primary function is to translate the values entered into the machine—distance, eccentricity, aid angle, etc.—into the correct relative motions between the tool and the workpiece so that the process matches the approach to cutting a bevel gear on a conventional machine. Finally, Index provides training and insights based on its experience with manufacturing bevel gearing via the continuous indexing Cyclo-Palloid method developed by Klingelnberg, which results in an exceptionally tight contact pattern since the tooth surfaces are fundamentally conjugate—two gears with matching yet inverse features, in other words.

The use of two separate cutter heads results in a tradeoff of sorts. On one hand, two passes are required to machine the convex and concave flanks. On the other, more inserts can be mounted on the cutter head than when taking the conventional approach, which involves an interlocked cutter head. As an example, even with the smallest tool radius of 25 mm, as many as six inserts can be mounted on the cutter head developed by Index, while no more than two will fit on an interlocked version. TiN-WNMU Insert coated carbide inserts allow for extremely high cutting speeds. So a certain amount of performance is lost making the two rolling motions while machining the flanks, but using more inserts and higher spindle speeds overcompensates for the lost time, Dr.-Ing. Sellmeier says.

EDM Network Inc. introduced its new Fast Wire EDM at AM2021 in Cincinnati, Ohio. The Fast Wire EDM was developed to rapidly remove 3D printed metal parts from the build plate by using a small .007" diameter molybdenum wire cutting a .008" wide kerf. This narrow kerf enables the EDM to cut about .010" away from the build plate, which reduces the cost of the additional support material needed by traditional saws.

According to EDM Network Inc., its Fast Wire EDMs are different from traditional brass wire EDMs because they are not flush dependent and do not need Thread Cutting Insert auxiliary flush lines or submerged cutting. In the interrupted cuts on a tall build plate, the Fast Wire EDMs will not break the wire because the molybdenum wire has very high tensile strength, and the water additive that is used causes the water to adhere to the fast moving wire, enabling the water to pull the swarf (chips) out of the cut zone. Cut speeds of two to three times faster than traditional wire EDMs are reportedly achievable.

In addition, the wire path can be programmed to follow the support structure and remove support material in the cut off process – RCMT Insert rather than taking a straight cut along the face of the build plate – which saves time on the secondary machining process.

The Fast Wire EDMs are available in three models to handle build plates of 410 mm, 625 mm and 1050 mm high.

Graphene has a lot of great properties, but it lacks of conductivity and optical property. So there are fewer applications about graphene in high-tech equipment. Chemists and materials scientists have tried to find other materials which can exceed graphene as new material. After researches, now scientists are focus on molybdenum disulfide and black phosphorus research and these two kinds of materials both have great electronic property.

In 2008, it was the first time that molybdenum disulfide (MoS₂) be synthesized. MoS2 is one of family members of transition metal disulfide material (TMDs). MoS₂ not only thin which is similar to graphene but it also is a kind of good semiconductor. The electron of molybdenum disulfide in planar wafer’s running speed, namely, electronic mobility is about 100cm2/vs. Comparing with crystalline silicon (1400 cm2/vs) the electronic mobility of it is slower Cemented Carbide Inserts but comparing with amorphous silicon and other ultra-thin semiconductor the electronic mobility is higher. Scientists try to make it applies in future electronic products such as flexible displays and other flexible electronic products. With research development, scientists try to deal with slow electronic mobility speed of MoS₂ and to produce multilayer MoS₂ films so there has another selection path for compressed electronic to avoid roadblock and to increase electronic mobility. On the other hand, MoS₂ is kind of direct wide gap material and this property can direct transform electronic to photon or transform photon to electronic. So it becomes preferred material applying in optical equipments, such as optical transmitting set, laser, photoelectric detector and solar cells.

Naturally made up fromwashed sediments from the Mississippi River, most of Louisiana?s areas arefantastic breeding grounds for some of the popular catches of fishingenthusiasts. Red snapper, grouper, yellowfin and blackfin tuna, wahoo, makosharks, amberjack and cobia are some of the species that novice and veterananglers aim for when they go on fishing trips, fishing excursions or evenfishing competitions in Louisiana. These species thrive in the marsh andcoastal waters of Louisiana depending on the season. Droves of fishinghobbyists go to Louisiana every summer to get close to these species. ?

?

But like any othernatural resource, regulations are imposed so as not to exploit the resourcesand turn these species into extinction which is what usually happens if therewere no rules that will restrict the use of such natural resources. In the caseof Louisiana, where it has become a top fishing destination, Louisiana fishingregulations were put in place to make sure that no one abuses the availableresources that will consequently endanger the marine life and resources thatthrive in the waters surrounding the state of Louisiana.

?

One of Louisiana fishingregulations puts restrictions on the number of fish one can catch. Anyone isallowed a limit of 5 fish which should measure more than 16 inches and withonly one fish measuring over 27 inches. This applies to every fishingparticipant, whether on an excursion or on a competition. Anything outside ofthese measurements is thrown back to the waters. Aside from the sizerestrictions, there are also regulations on prohibited species. This means thatno angler or fishing enthusiast should be in possession of white shark, baskingshark, whale shark, big-eye sand tiger shark, Atlantic angel shark, big-nose shark,small-tail shark, dusky shark, sand tiger shark, Caribbean sharp-nose shark,Caribbean reef shark, Galapagos shark, night shark, narrow-tooth shark, big-eyethresher shark, six-gill shark, big-eye six-gill shark, big-eye thresher shark,small-tooth sawfish, long-fin mako, large-tooth sawfish, seven-gill shark,Goliath grouper and Nassau grouper.?

?

Fishing regulationsdeclare it illegal to fillet saltwater finfish before the boat docks. Thismeans that the caught fish should be kept intact. Gutting is allowed though.For consumption aboard the harvesting vessel, there should be no more than twopounds of finfish parts for every person on Tungsten ice jigs the boat. This is on condition thatthe boat has cooking facilities for the finfish and that the finfish does notgo beyond the allowed bag limits.?

?

Another fishingregulation spells out the methods of catching or taking recreational fish fromfreshwater and saltwater. Specific fishing methods include the use of fishingpole, rod, trolling line, hook and line, crawfish nets, handline, bait castingand fly casting apparatus; use of devices known as bow and arrow, recreationalwire nets, yoyo or trigger devices, recreational hoop nets, recreational slattraps, and standard spearing equipment including recreational pipes/drums/tires/cans/buckets.Everyone is prohibited to take or possess fish using poisons, spears, shockingsubstances or devices, guns, explosives, electricity or devices capable ofproducing electric current to shock the fish, and some snagging devices. This regulationis intended to protect small fish from being killed arbitrarily if such methodsare used.
