With it acquisition of DuPont’s engineering resins, Celanese’s resin solutions for automotive electrification, e-mobility and consumer electronics are plentiful.

Comp Cams’s goal is to be a leading developer of innovative valve train components, Mr. Godbold explains. Machining is viewed as a means to that end. Mr. Godbold says companies with a similar approach are well-served to recognize their manufacturing limitations, especially when considering the addition of a complex lathe like the LT-300MY. It’s best to devote some time to learning the ins and outs of such a machine before depending on it for production, he notes.

The company ultimately decided to go a different route after Mr. Godbold met with Larry Schwartz, who at that time was Okuma America’s president (he’s now the machine tool builder’s chief strategy officer). The men discussed alternate ways to manufacture camshaft cores that would minimize change-overs and simplify setups for production runs of 20 or so pieces. Mr. Schwartz’s idea was to use a twin-spindle/twin-turret lathe. Keeping a bar either clamped between the spindles and/or partially inside of them would enable complete machining of camshaft cores in one setup. Plus, the twin spindles could perform some operations simultaneously.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

The lathe then turns and mills features into the front face of the camshaft. Next, the sub-spindle pulls the bar out for grooving...

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

The photos on the following page show how camshaft cores are produced on the lathe. An operator manually slides a pre-cut bar into the main spindle, pulls the bar out a few inches to a stop, and clamps it. The lathe then turns and mills features into what will become the front face of the cam. Next, the subspindle moves into position, grabs the machined face and pulls out the bar approximately 10 inches. Grooving and lobe milling are completed on that segment of the bar. Once machining on that section is completed, the subspindle clamps onto some of the newly machined journals and pulls the bar farther out of the main spindle to enable grooving and lobe milling of the back half of the camshaft. (Performing these operations in two small sections minimizes the risk of deflection, vibration and chatter.) Finally, the subspindle consumes nearly the entire bar to enable turning and milling work on the back face of the camshaft.

Paul Runyan, VP Sales & Marketing at Accumold, says. “The critical importance is to integrate seasoned micro-optic suppliers like Accumold into the design phase as early as possible. It’s our partnership approach, versus a mere vendor relationship, that enables the fusion of specialized micro manufacturing and micro-optic expertise into your projects for solutions that are both efficient and economical. We are able to produce micro-optic marvels such as 250-micron fiber optic lenses, parallel arrays, demux devices, and diffractive lenses, enhanced by our experience in molding attenuated resins and applying coatings like IR, AR, and reflective layers onto plastic substrates. The complex demands of crafting micro-sized optical couplers, embedding lenses into housings, replicating lens profiles to a quarter wave accuracy, and achieving lens surface finishes within 50 angstroms are why we have dedicated tooling specialists to ensure your light transmission projects are flawlessly executed.”

Each turret has three different grooving tools. Two of those perform roughing operations. The wider of the two is used as often as possible, while the thinner one is used only when space is tight. The third grooving tool is used for finishing, leaving behind a quality, burr-free surface finish while holding dimensional tolerances of less than 0.010-inch on all linear dimensions along a 24-inch-long camshaft.

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

Runyan concludes, “The exacting tolerances inherent in micro-optic applications, necessitate that OEMs collaborate with seasoned experts like Accumold from the outset to achieve precise, timely, and cost-effective manufacturing outcomes. We invite all Photonics West attendees to join us at booth 1566, where we’re excited to showcase our successes in micro molding and discuss how our expertise can elevate your micro-optics projects. Engage with our expert team and let’s explore how our partnership can illuminate the path to your product’s success.”

Once that section is completed, the sub-spindle consumes the machined section and pulls the bar out further to repeats those operations on the back section of bar.

Accumold’s history in the micro optics marketplace spans decades, and the company has proudly partnered with leading SMEs and major international corporations to craft ground-breaking products that push the boundaries of innovation. In the photonics sector where supreme precision is not just desired but required, Accumold has cemented its role as the micro molding authority for OEMs seeking to create components that are not only complex and diminutive but also precise, timely, and cost-effective.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

With that said, the company continues to work closely with Rex Luxmore, its Iscar tooling representative, who Mr. Freeman says is proactive about keeping him up to date with new tooling developments. For example, Mr. Luxmore’s recommendation of grooving tools with a new coating resulted in a 30- to 50-percent improvement in tool life. This assistance is critical, Mr. Freeman notes, largely because of the challenging materials such as M4 powder-metal tool steel that the company frequently machines. This tool steel is not only very unforgiving, but it will work-harden quickly if cut too slowly or lightly.

The company has also standardized on coolant, using the same Castrol Syntilo 9918 synthetic coolant for machining that it does for grinding. Mr. Godbold says the company could save money by using a lower-cost coolant, but it appreciates the consistent performance the advanced coolant offers. Comp Cams plans to install an 8,000-gallon central coolant system with a single main paper filter system to supply both the machining and grinding areas in the facility.

Another early challenge was getting used to P codes, which are used to synchronize the motion of the two turrets. P codes not only ensure that the turrets don’t interfere with each other when performing separate operations, but also can signal them to perform identical operations simultaneously. For example, if a programmer wants to face a part with the upper turret and then drill the end of it with the lower turret, those operations have to be synchronized because they obviously can’t be performed at the same time. If the programmer assigns a P10 value to the upper turret and a higher P20 to the lower turret, the upper turret will continue all of its necessary motions until it encounters a higher P value in the program code. If the next P code it encounters is higher than the P code assigned to the lower turret, the upper turret will wait until lower turret is done. However, if the same P code is applied to both turrets, they will work simultaneously.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Mr. Godbold believes this approach made all the difference in the world. He humbly says that Comp Cams proves that a shop with only conventional turning and milling experience can successfully integrate a complex multifunction machine without necessarily being outstanding at machining or programming. However, this requires establishing solid relationships with equipment suppliers that are willing to help a shop achieve its goals. Finding trusted people to work with means everything, he says.

Mr. Godbold explains that Comp Cams’ traditional expertise was in grinding camshafts, not machining them. So when the decision was made to install the seven-axis multifunction lathe in 2008, the company relied heavily on the expertise and advice of its equipment suppliers to establish an effective machining process. Comp Cams continues to tap those resources today as it strives to minimize cycle times for camshaft cores.

Prior to the lathe’s delivery, Comp Cams sent what it thought was a very difficult camshaft core to Okuma’s facility for machine prove-out: a 70-mm-diamter NHRA Pro Stock camshaft with nine journals. Kevin Kraieski, an applications engineer for Okuma, created the initial part programs and machined the first sample parts. Mr. Kraieski set up the part program using multiple variable-style sub-routines for commonly required operations, such as grooving between lobes, milling lobe profiles, drilling and tapping bolt hole patterns, and more. This made it possible for Comp Cams to easily reprogram the complex machine for any number of camshaft designs without starting from scratch each time.

This Adcole cylindrical coordinate measuring machine orients camshafts vertically for measurement results that require no need for sag correction. It takes less than a minute for an operator to enter camshaft feature specifications to measure.

Comp Cams has refined this process to the point that it can now machine camshaft cores in 35 to 45 minutes. That said, the company had to overcome some initial machining hurdles in order to achieve these faster cycle times.

Quick-change tooling on a live-tooling station saves time during production my eliminating the need to touch-off tools each time they are installed.

Workpiece slippage inside the jaws also proved to be problematic at times because some camshaft materials are more difficult to clamp tightly than others. The solution was applying a tungsten-alloy coating from Carbonite Metal Coatings on the gripping surface of the jaws. This particular coating is applied via electrofusion, which creates a metallurgical bond that is said to be stronger than spray-on coatings. The coating has virtually eliminated linear and angular workpiece slippage from occurring during machining.

Each turret on the LT-300MY has 12 tool stations. Daniel Freeman, the R&D technician for Comp Cams who commonly programs and helps run the lathe, says the company takes full advantage of those 24 total stations. Approximately two-thirds of them rarely change. In addition, tools in several stations are mirrored on both the upper and lower turrets to facilitate the simultaneous machining operations.

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

Longer 6-inch jaws on the sub-spindle enable it to clamp at least two journals of every camshaft Comp Cams manufactures.

Today, Comp Cams machines small batches of racing camshaft cores on a twin-spindle/twin-turret lathe from Okuma. (Camshaft cores are camshafts that have their primary features machined, but still require subsequent heat treating and grinding operations.) Bringing this machining capability in-house enabled the company to greatly speed turnaround of custom camshafts for professional racing applications because it no longer had to wait weeks or months to receive camshaft cores. It can now manufacture as many as 12 M4 powder-metal tool-steel camshaft cores in a single eight-hour shift.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

Originally, the prolonged camshaft-core delivery times had the company considering adding a “conventional” cell to produce the small batches that race teams required. Such cells typically include a saw to cut barstock to length; lathes to face the front and rear of the camshaft, add centers and groove the lobe layout; mills to machine details in the front and rear camshaft faces; and additional mills to machine the lobe profiles. Most of these operations required multiple time-consuming setups, too.

On booth 1566 at Photonics West, Accumold will be showcasing its expertise as the world’s leading high-tech manufacturer of precision micro molded plastic components with part geometries from 5cm to less than 1mm in size. The company’s 30-plus years at the forefront of micro molding innovation ensures that it leads with expertise in insert molding, clean room molding, and 2-shot molding across materials like PEEK, Ultem, LCP, and a wide range of engineered thermoplastics.

Improving finish in the grooves between the lobes and increasing lobe machining speed proved to be challenging during testing. However, Tim Whitmore, an OEM project manager for Iscar, work closely with Mr. Kraieski to iron out the tooling issues. By the time the machine was delivered to Comp Cams, it could complete a M4 camshaft core in 75 minutes.

One advantage of standardization is that it minimizes the number of tools that must be touched-off for a new job. Typically, an operator has to install and touch-off only a few drills, reamers and taps during setup for a new job. Tool standardization also enables programmers to quickly and easily determine whether additional tooling is needed for a new project. Ultimately, standardization has enabled Comp Cams to reduce change-over times for most new jobs from an entire day to just a few hours.

Unless a camshaft has an odd number of grooves, the lathe performs turning and grooving operations using both turrets simultaneously when the bar is held between spindles. Because the upper turret is optimized to run close to the main spindle and the lower one is set up to run close to the subspindle, the company does not perform pinch turning. However, Mr. Godbold estimates that simultaneous cutting enables the lathe to remove material 30 percent faster primarily because the tool pressure is balanced. In addition, starting the grooving operations at the middle of each section of bar and moving out toward the spindles leaves more stock at either end of the bar section. This ensures rigid support to prevent chatter and also eliminates flexing at weak areas of the bar, which could possibly pinch or break a grooving tool.

The lower turret contains center drills used for both the front and rear camshaft faces. This turret also has live horizontal stations set up to create features such as vent holes. Two stations contain miscellaneous tools. These include a multifunction drilling/boring tool that is typically used to create counterbores, and a large indexable-insert drill that machines bores on the rear of a camshaft.

When I first spoke to Billy Godbold, he was at a track watching a professional drag racing team test a custom camshaft. Mr. Godbold is the engineering group leader for Comp Cams, the valve train component manufacturer that supplied the camshaft. One month earlier, Comp Cams’ design group had just started contemplating camshaft materials and geometries for this application. Moving from design to completed billet camshaft so quickly would not have been possible years ago when the company outsourced the machining of its high-end racing camshafts.

The company selected an Okuma LT300-MY. Mr. Godbold says that in many ways, the initial concept and programming execution were greater hurdles than the slight machine modifications that were needed for this application. The primary mechanical change to the machine was increasing the size of the sleeves in the main and subspindles so a 70-mm-journal camshaft could pass through them. The company reasoned that because the machine offered a great deal of rigidity and each of its spindles provided 30 horsepower, the lathe would have no problem machining the tough M4 powder-metal tool steels (rated at 30 HRc) common to its billet racing camshafts.

As it turned out, the “really difficult” camshaft Comp Cams sent to Okuma for testing proved easier to machine than its other camshaft models. That’s because the camshaft’s nine journals provided more clamping points for the subspindle than a typical five-journal camshaft. Consequently, the original subspindle jaws were not long enough to clamp across at least two journals on the five-journal models (this was necessary to ensure adequate support during machining). Installing lengthier 6-inch jaws enabled the subspindle to clamp across two or more journals on any type of camshaft the company manufactures. The main spindle always clamps solid barstock, so longer jaws are not necessary for that spindle.

The company uses Exsys/Eppinger Preci-Flex ER32 quick-change adaptors for some of its live-tooling work. Each adaptor can accommodate a drill, tap or mill for use in that single station. During setup, each tool is separately installed in the adaptor and touched off. During a production run, a program stop pauses the machine and prompts the operator to change the tool in the adaptor station to the next tool needed. The operator can change the tool in less than one minute, and touch-off isn’t necessary because the offset for each tool was determined during setup. Mr. Freeman says tools in the adaptor extend out a couple inches farther than normal, but this does not present any clearance issues.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

The upper turret has two vertically oriented end mills of different diameters that remain in their respective live stations. These are used in conjunction with the machine’s Y-axis movement to perform lobe milling. The narrower 0.75-inch end mill has one less insert than the 1-inch end mill, so the feed rate has to be reduced when that tool is used. Tools in the upper turret’s five horizontal live stations often don’t change either. These perform drilling, tapping, reaming and other operations on the front face of a camshaft.
