Perfecting Putters with OneCNCOct 14 2009
YAR Golf, located in Arizona, proudly engineers, manufactures, and assembles their exclusive putters in Tempe, Arizona USA. The uniqueness of the YAR GX1 Putter is unparalleled, with a specific design concept that allows players to up the ante in their golfing game.
YAR Golf has created the only Golf Club / Putter in the golfing industry that has ever been accepted by USGA for their Adaptive Golf Program. This year alone there were 19 other devices submitted and rejected by the USGA’s Executive Board for this distinction. Capable of lifting the golf ball out of the cup without the player needing to bend. Aging baby boomers and the physically impaired is not their only clientele. YAR Golf is the only company that has focused on their specific needs in the game of golf by designing a putter that has features intended to enhance the game of players at all skill levels.
Created by a Materials Science and Engineering PhD. The YAR GX1 Putter has many features that set it apart from the standard putter designs, which have been left unchanged and stagnant for quite some time. Using MOI (Mass Moment of Inertia) and Parallel Axis Linearization combined with Aeronautical Physics, its design and shape have created the largest true Sweet Spot in the Putting industry, this phenomena is not found on standard putters, as the YAR putter’s entire face is considered a ‘sweet spot’.
In a 2009 study, the YAR putter was put to the test by Golf Test USA. They summed up that the YAR putter performed beyond its claims and it received the highest ranking among putters worldwide. From Golf Test USA “…because of its design and balance it was very easy to putt with just one hand. The overall design of the YAR putter can help any golfer who has physical limitations such as bending over due to back pain. The YAR putter can easily mark the ball and pick it up at the same time, and pick the ball up out of the hole. It can also be used to pick other clubs off the ground. This is the perfect putter for “adaptive” golf. The YAR GX1 putter was one of only 8 putters, out of 47, awarded a 5 star rating based on overall test results. The YAR Golf GX1 putter has received our coveted “Seal of Excellence” [for its outstanding results]”
Dr. V, the creator of the YAR putter, contacted OneCNC in 2007 looking for a CAM solution to make her new concept a reality. Because of the secrecy involved in the YAR putter concept and patent, all prototyping needed to be completed in house. Knowledge in the CNC Machining industry was minimal for Dr. V, so an easy to use and powerful CAM program was paramount. After evaluating over 6 different CAM programs a one-on-one online demonstration was scheduled with OneCNC’s technical support. “OneCNC was superior to the other CAD/CAM systems I appraised. It was easier, offered more design tooling procedural advantages, was a pleasure to acclimate with, and the technical support representative was the most knowledgeable. In fact, I purchased an upgrade the day after my initial 1-hour consultation, and I have never regretted that decision”.
Running XR3 Mill Professional gave Dr. V full control over the designing and machining of the YAR putters.
When asked about OneCNC’s technical support and customer service she stated, “The OneCNC support and office staffs are awesome, caring, and spectacular. Kudos and accolades to all at OneCNC.
Yar Golf has donated over $50,000 in GX1 putters to disadvantaged golfers and charities around the world and is the Official Putter of numerous Disabled Organizations; as well as their “Support a Disabled Veteran” project, which supplies free golfing equipment for disabled American Veterans.

OneCNC CAD/CAM software builds confidenceSep 25 2009
Nick Groom (below) uses the OneCNC CADCAM system to help program a complex component for mill-turning on one of the company’s Star sliding-head lathes.
From a low point at the start of 2009, business at precision turned parts subcontractor, Qualiturn, has increased month on month throughout the year. But, said managing director, Nick Groom, a typical batch size ordered by customers is currently 1,000-off, which is about 50 per cent lower than last year.
It is more expensive to produce smaller quantities, as set-up time becomes a larger proportion of total manufacturing time. It should mean that the unit cost to the customer is higher, but in a recession, it is difficult to pass on the cost increase.
In these circumstances, to allow it to make reasonable margins, Qualiturn has managed to minimise set-up times through ongoing investment in engineering software and computer-controlled storage systems for raw material and tools. With 70 set-ups per week, the importance of streamlining procedures is evident.
The latest investment, in June 2009, was the purchase of CADCAM software from OneCNC. The Windows-based module has integrated functionality from CAD design though to machine posting. The package allows electronic 3D data supplied by customers to be translated and converted rapidly into NC code for running on the company’s 16 Star sliding-head CNC lathes and two Miyano fixed-head mill-turn centres.
Commented Mr Groom, “Customers are asking us to produce increasingly complicated components to ever higher accuracies. Until recently, we had to program 3D profiles manually, which often delayed the start of production.
“The OneCNC software generates complex tool paths directly from the original CAD data, which is quick and eliminates the risk of human error.
“We still write the remainder of the program at the machine control, as it is faster for simple routines. The two parts are then merged to create the final code much more quickly than previously.
“It is also possible to simulate a cutting cycle on-screen to make sure a program will run as expected.”
Lead-time from receipt of order to first article inspection of complex components is therefore faster than before, helping to reduce set-up time. Assisting further in speeding changeover is rapid delivery of material and tools to the machines, helped by Qualiturn’s investment in a 7.5 m-high tower for storing bar stock and a smaller version for housing tooling and machine attachments.
The latter was installed at the end of 2008, making it faster to access collets, bushes, toolholders and other items than when they were held in chests of drawers on the shop floor. Some boxes of special cutting tools are also housed in the multi-level store along with toolholders for regularly repeating jobs, but most cutters and tips are stored in an Autocrib.
The subcontractor operates the multi-level tool store differently from the bar store. The latter is linked directly into a PSL Datatrack production management system, which automatically calls up the bar and delivers it to an unloading area at floor level as a job starts its progression through the Hertford factory. Within the tool store, the content of each shelf is similarly held within the Datatrack memory, but the operator manually keys in the appropriate shelf number at a control panel to access the tooling.
Speeding machine set-up not only makes smaller batches more economical but also reduced spindle downtime, helping to extract maximum productivity from all of the subcontractor’s plant. Attendant technologies from job sales order processing and workshop scheduling through to CNC inspection and billing, all linked into and overseen by Datatrack, similarly contribute to maximising throughput.
So too does the speed of the latest CNC lathes, which have higher feed rates and spindle speeds and enhanced capabilities compared with machines that are just a decade old. So Qualiturn adopts a policy of renewing its machines after eight years at the latest. The most recently installed Stars, for example, have up to 35 m/min rapids and are capable of cutting cycles that are twice as fast as older machines. Along with quicker set-ups, the inherent speed of modern machines also helps to lower unit production costs.
A further contribution to this goal is Qualiturn’s consultancy service, whereby a new component design can be reappraised and suggestions made as to how it could be modified to reduce the cost of machining. The service is provided at no extra charge, on the basis that the subcontractor’s service will give it a commercial advantage.
Real cost savings are possible. Mr Groom points to a recent aerospace job where Qualiturn engineers looked at different shaft diameter and material combinations to optimise production of a non-critical component. In another example, a 15 per cent cost reduction was achieved when machining an automotive component by mill-turning it in one hit from 20 mm diameter brass bar rather than using expensive extrusion.
Although 1,000-off is a typical batch size for Qualiturn and turnaround time is currently one to two weeks, Mr Groom stressed that his company regularly produces 10,000- and 20,000-off, but less frequently since the start of the year.
He concluded, “At the moment, a lot of our customers do not want to order large quantities and tie up money by holding inventory. So they are tending to opt for smaller batches and order them more frequently for just-in-time delivery, even though it costs a bit more.
“On our side, we cannot risk producing more than the customer orders and stocking the surplus on consignment, as designs can change and products can be discontinued.
“So our efforts to reduce set-up times have been crucial in the current economic climate. They have allowed Qualiturn to mitigate the extra cost of producing smaller batches and enabled us to adapt to market conditions by offering lower prices and faster delivery.”
