Greetings to all of our friends engaged in manufacturing with clamping systems,

my name is Sebastian Herr. I am HURCO’s Director of Application Technology.

In the following posting, I will be furnishing you with additional information regarding our “Milling a connecting rod” video.

This video shows you the process employed to produce a stainless-steel connecting rod using 5-axis machining. This example clearly demonstrates that processing with trochoidal milling using the HURCO control system is the absolute equal of procedures using the CAM systems as employed by our associated firms. The basic concept remains the same: The tool executes a rotary motion as it proceeds into the workpiece in a penetration process that continues until it is completely immersed and thus able to mill across the entire length of the cutting tool. Throughout the entire processing cycle, the motion pattern is continuously adapted to maintain an invariable and consistent clamping center.

The connecting-rod processing operation that you now have the opportunity to witness is an impressive number. We programmed the pocket milling using TopSolid, which has also been incorporated in our dialog programming. With the HURCO system, the process flows with such seamless smoothness that the simulation displays no detectable difference. The procedures for tool installation and machine set-up also remain absolutely identical, while the program proceeds with no pauses or interruptions of any kind. This unites two technologies in a closely knit combination: HURCO contributes the foundational dialog programming while the CAM builds upon this basis with the DIN-ISO code.

I really want to emphasize that the NC programs are fully integrated in the control system’s programmed conversational operating concept. We didn’t make the decision to apply the CAM system because we had to; we use it because it works! And above all, because it represents the ideal answer to the typical quotidian conditions encountered in contract manufacturing. These environments frequently encompass multiple machines and operators, but just one or two CAM work stations. Under these conditions, a control system offering immense flexibility is an extremely welcome addition. An essential asset is how this system allows programmers to integrate programs stemming from a variety of sources. The only required qualification is a solid background in machining and metal cutting. When we compare the systems, all that the HURCO operator needs is some basic training in the realm of conversational control systems, while the competitors’ systems demand extensive expertise, available only at the cost of considerable time and expenditure.

Now I would like to draw your attention to several special features related to the actual machining process. Right at the outset, we focus on the topic of “automation” by showing you the pallet-loading process. In addition to our own in-house products, we also offer solutions for both component and pallet loading contributed by our close associates at ROBOJOB and EROWA. The present scenario focuses on a solution provided by EROWA. At the same time, we remain open to any and all viable automation concepts that might be needed to meet your own specific requirements.

We commence by showing you heavy stainless-steel blocks weighing in at roughly 60 kg, or just over 130 lbs., on two small clamping modules (each 75 mm in width) sourced from LANG TECHNIK. In the interests of achieving secure clamping, the casting has been endowed with an indentation approximately one millimeter in depth and 125 millimeters wide at its lower edge. The casting is processed using a hydraulic mechanism that presses the clamping module’s teeth into the block. The clamping process thus produces a tight positive fit providing immense retaining forces while relying on relatively modest clamping force. This contributes an array of assets of considerable value in the machining and metal-cutting process. It allows the clamping system to serve as a cushioning assembly, resulting in a substantially smoother machining operations. At the end of the day, this means that the connecting rod can be machined at relatively constant load factors combined with a high level of machining performance – in a secured process, despite the high superstructure.

At this juncture, I would like to call particular attention to the simulations of the raw casting and finished part along with the ability to import 3D solid models from the CAD to the control system. This feature is made possible by the “Solid Model Import” option. Starting at second 10, you will be able to see the solid model for the processed part as well as the superimposed casting upon which the machining operation as defined in the control system is simulated. This allows you to check to ensure that everything is proceeding according to plan at this point. From second 39 onward, you receive a clear simulation of the raw casting and machined part, allowing you to monitor the machining path and the rate of metal removal. You can easily view the machine’s current motion patterns along with the depth at which the milling tool is currently operating within the workpiece.

This connecting-rod machining process thus illustrates multiple facets of our approach: The ease with which a DIN/ISO subprogram can be incorporated in the dialog programming as well as the flawless flow of the processing simulation – all in a single cycle. Also apparent is the smooth functionality displayed during execution of potentially difficult metal-cutting operations on stainless steel. The special clamping mechanism ensures minimal vibration. The foundation is furnished by an adaptive milling strategy that can be utilized to full potential thanks to the machine’s vibration-damping properties. In addition, the casting webs to which the connecting rods are attached can be machined so thinly that they can simply be broken off once the machining process has been completed. It is now possible to grind off the burr, at which the connecting rod is finished – in one machining operation and with one clamping process.

THERE’S NOTHING UNUSUAL about building a custom motorcycle with the primary purpose of taking it to a show. But what if the show in question has absolutely nothing to do with custom motorcycles? That’s a cool twist.

The pet project of Maxime Fontvielle

This sharply styled Yamaha SR500 flat tracker is the pet project of 27-year-old Maxime Fontvielle. He’s an application engineer at the French operation of the US machine tool company, Hurco—a career he got into thanks to a love of two wheelers.

“When I was a teenager,” he tells us, “I was passionate about mopeds. While looking at the forums, I saw people making parts for competitive 90s mopeds and I thought, that’s what I want to do! I went all the way in with apprenticeships at different companies, then I arrived at Hurco.”

Maxime stumbled upon a wrecked Yamaha SR500 for just €100, and had a bright idea: rebuild it as a showpiece for his company, to take to machine industry trade shows.


The other exhibition part

Maxime stumbled upon a wrecked Yamaha SR500 for just €100, and had a bright idea: rebuild it as a showpiece for his company, to take to machine industry trade shows.
“Every year at the trade shows,” he says, “all the manufacturers show their new machines in action with classic parts from the aviation industry, etc. I thought it lacked a bit of passion and soul.” “I wanted to make a beautiful bike with machined parts on it. I proposed to my boss that I prepare this bike as a real flat track beast. American discipline, American company… this is a match!”

Maxime’s boss wisely gave the OK—but there was a tight three-month deadline before the next show. So Maxime decided to divide and conquer. He entrusted the engine rebuild to the Parisian workshop Machines et Moteurs, with a very specific checklist, while he focused on the chassis.
The motor came back with a 540 cc kit and a heck of a lot of internal fettling. Highlights include an upgraded camshaft, improved oil flow, a Mikuni TMR36 carb and a K&N filter. There’s also a new header and reverse cone megaphone muffler, both from SC Project in Italy.

Piece by piece to a unique piece

Maxime’s first job on the chassis was to install a 19” rear wheel to match the front. He ended up sourcing a second SR unit, and machining it to take a sprocket and a 300 mm brake disc. Then he machined custom wheel axles, adapted the front to run with bigger bearings, and lightened both wheels by ‘splitting’ the spokes.

There’s no brake on the front, but there’s a Brembo caliper and master cylinder out back, linked by a braided stainless steel line. Since Maxime was upgrading the bike from a rear drum brake, the whole arrangement is custom—right down to the caliper bracket and foot controls.

Up front is a set of Yamaha XJR1200 forks, with a custom steering stem, yokes and bar risers. Out back are a new set of shocks, hooked up to a custom swingarm—a part that Maxime’s boss requested, to show off Hurco’s machines’ capabilities. Made in partnership with the CAD/CAM company Mastercam, it’s tailored specifically for this bike—with little details like a caliper support mount, and paddock stand supports.

 Custom Bike in Hurco color

It’s a subtle part that needs to be appreciated up close; but so are the other custom touches on this Yamaha.
From the engine covers to the chunky foot pegs, to the entire kickstart lever and pedal, Maxime’s gone to town without going over the top. Look even closer, and you’ll spot more, finer details—like the logos etched into the sides of the yokes.
Up top is an Airtech Streamling tail piece, matched to the OEM fuel tank, a front number board, and a set of flat track bars. For the livery, Maxime’s brother, a designer at the Austrian design powerhouse Kiska, helped out with over thirty mockups—all of them using Hurco’s corporate colors.

Everything’s now finished in black and grey, with two shades of blue for accents (one for paint, and one for anodizing). Another buddy, Jerome, took care of the decals; a nod to all the partner companies that worked on the project.
Not only does the SR look hella sharp, but it’s also reportedly a treat to ride. Maxime plans to get sideways with it on a flat track soon… but until then, its main job is to put Hurco’s next trade show booth head and shoulders above the rest.

Reduce programming time, avoid programming errors

Pliening, March 2018: Solid model import option simplifies programming for HURCO machines

Programming on 5-axis machines from HURCO can be performed easily and quickly. New and less specially-trained employees can be trained in a short period of time.

The new “solid model import” option further reduces the steps. Machine tool manufacturer HURCO has enabled connection of its machines to a solid model import.

The programming time is reduced and simplified through simple data importing in the STEP 3D model format. The import option interprets the data and makes production programming directly at the machine possible. The path from workpiece to component becomes more secure as well. The potential for error during programming is reduced many times over, partly because the machining simulation of the written program is shown together with the solid model in a single view. Thus, users can immediately see if the programming matches the finished component and can refinish this component if necessary.

Increased profitability through fast programming

HURCO machines are equipped with the intuitively operable “Max5” conversational control system. “Our control system is an absolute highlight and unique feature of ours”, Michael Auer, Managing Director of HURCO GmbH, emphasizes. “It is the fastest in the industry and vastly increases the machine’s efficiency.” DXF files can be directly imported into the CNC control system. Drawings or sketches are imported quickly into a finished program, which contributes to increased profitability in prototype, single piece and small series production.
