Already a versatile moldmaker specializing in larger and/or more complex tools such as stack molds, gas-assist, and multishot, Triangle Tool Corp. (Milwaukee, WI) has fully moved into the 18,000-ft2 expansion housing its new bridge-style 5-axis Mecof machining center. Specialty machining of large pieces is adding substantially to the moldmaking business.

This newly added 5-axis Mecof machining center is prominent in Triangle Tool’s recently opened expansion, but there is space for additional CNC systems.

Company sales manager Vic Baez says, “Triangle Tool had perfected high-speed machining through our mold building business. We bought this machining center knowing that our customers wanted faster machining with greater accuracy for their large pieces, and the Mecof does just that.”

The Italian-made Mecof system offers table travel distance of over 31 ft, and is one of more than 15 4- and 5-axis systems now operating at Triangle Tool. Baez says Triangle was amazed at the response from companies all over North America once the company had open time for custom machining. Business is coming from the defense, aerospace, and wind-energy sectors, among others, and additional CNC machining centers will soon enter the new expansion.

Triangle Tool’s total floor space, including the new addition, is now about 173,000 ft2, and the company has added nine employees since the addition opened. Between its Milwaukee headquarters and its A-1 Tool Corp. facility in Melrose Park, IL, the company now employs over 160 persons.

Software Proves to be a Valuable Fixture

cnc,cnc machines,cnc milling machines, cnc lathe,used cnc machines December 30th, 2009 by cnc machines cnc manufacturers Industries,cnc machine tools,cnc programming,cnc controller admin

M&M Manufacturing in Tulsa is a CNC machine shop producing parts, assemblies and tooling for the energy, healthcare, and manufacturing sectors. But, the shop’s specialty is in complex-geometry aerospace components. It uses four- and five-axis machines to manufacture parts that often have three controlling datum surfaces, as well as many contoured surfaces blending into each other.

Gulfstream G-650 fitting

These parts are programming challenges that M&M addressed with a switch to DP Technology’s ESPRIT CAM. The software makes it possible to apply toolpaths directly to a customer’s solid geometry and view simulations of the resulting program, with the machine, tools, fixturing, etc., included, to avoid crashes.

Creative Workholding, Machining

Machining plan for a Gulfstream G-650 fitting, as demonstrated by ESPRIT software.

“A key difference that we bring to our customers comes through our

creativity in developing a strategy for holding and machining the part,” said Ken Statton, president of M&M Manufacturing. Statton said the shop developed expertise in fixturing as it worked to meet tight tolerance requirements, but these efforts have advanced to using fixturing to reduce machining cycle time. He pointed to a four-station fixture that M&M developed for a four-axis machine that makes it possible to perform a tool change then proceed sequentially through all the operations with that tool on all four parts. “This fixture allows us to machine four parts with only a single sequence devoted to changing, advancing, and retracting the tool,” he said. “The result is substantial time savings.”

M&M began to move to four- and five-axis machining because of the increasing complexity of the aerospace parts it is producing, and this meant it needed a software package that could import complex geometries. It chose ESPRIT because of its programming simplicity and optimizing ability. “ESPRIT gives us the optimum level of control to make sure the cutter stays in the cut as long as possible and that the program works the first time we run it,” according to Statton.

Automatic Feature Recognition

In the past, for example, if the company was making a composite layup tool with many changing contoured surfaces, it had to define each surface independently and generate toolpaths. The cutter had to move around to reach each of the different toolpaths, typically taking several days to generate the program. With ESPRIT, programmers simply import the solid model and access the full functionality for the solid model. Then, the CAM software is used to integrate the solid model to automatically identify the part features.

The next step is to assign metalcutting operations to the features that have been defined. ESPRIT lets users create a knowledge base of pre-optimized machining operations that include a particular tool, cutting speed, feedrate, depth of cut, etc. Programmers choose from several different machining strategies that automatically develop an efficiency approach for machining the feature.

Original thinking wins business

cnc,cnc machines,cnc milling machines, cnc lathe,used cnc machines December 15th, 2009 by cnc machines cnc manufacturers Industries,cnc machine tools,cnc programming,cnc controller admin

Chris Carter of Barker Collins says that innovative thinking has allowed the company to make dramatic savings in machining times. This has given customers much shorter leads times and lower machining costs – and has fuelled growth at the subcontractor.

The machining of large clevises for off-shore platforms demonstrates the Barker Collins approach

The machining of large clevises for off-shore platforms demonstrates the Barker Collins approach

The continuing success of this ‘excellence through innovation’ approach depends an approach that is not constrained by taking the easy option or relying on traditional machining and working practices. This is complemented, says Chris Carter, by ‘putting our money where our mouth is’ in terms of investing in fit-for-purpose machine tools.

“We have to be prepared to invest in the most viable equipment that will turn our ideas into reality – machine tools that can be relied upon to generate the envisaged results,” he says.

Over the last six years, Barker Collins has carefully invested more than £1 million each year in high-tech machines, and each installation has been to a specification directly targeted to achieve specific, planned results and, effectively, to enable the company to take methods engineering to a higher level than competitors.

“You have to develop the willingness to spend to develop each process; getting it right invariably leads to higher rates of return – both for us and our customers. Indeed, in our case, the resulting successes then create the funds required for the next equipment purchase, and this enables us to continually move the business forward.”

The machining of a 100 pairs of large clevises for off-shore platforms is one example of the approach, says Chris Carter, who points out that having a series of CNC horizontal boring machines offering machining envelopes of up to 3,000 mm by 2,000 mm by 1,300 mm in X, Y and Z axes, gives the company the freedom to properly tool up and program the parts without being hampered by constraints on capacity, power and accuracy.

“The result,” he says, “is that the customer benefited from savings in machining cycle/lead times and, as a result, lower machining costs.”

He continues: “Rather than turn a 1 m diameter, as was tradition on this part, we interpolated the diameter on the five-axis horizontal borer, milled the face and an adjacent large spigot diameter, then drilled a series of 36 holes of 20 mm diameter on a pitch circle diameter on the flange.

“The table was then indexed and the main clevis bore was rough and finish bored through twin flanges that form the outer connecting yoke of the component.

“Similarly, on a mating end cap component, in addition to producing the main bore some 350 mm diameter through the forging, the machine table was indexed 90deg to face and bore a large spigot, followed by threadmilling in the bore for a critical M280 x 4P-6H thread some 300 mm deep. The process had to maintain a surface finish within 1.6 Ra on the flank of the thread.”

Discussing the methods and techniques used on such high risk and complex components, the Barker Collins team always interfaces with customer and listens very carefully to the problems before determining solutions.

“As a result, we set out operational methods, determine fixturing to support the part correctly to eliminate vibration and distortion,” continues Chris Carter. “Then we set about developing the tooling and the machining program before deciding how the part is going to be measured and qualified.”
