“Attention to detail wins races,” states Michael Tummond, engine engineering manager at <a href="http://www.americanosports.com/legacy-motor-club-parts-ways-with-nascar-rookie-noah-gragson-after-suspension-mike-rockenfeller-takes-the-wheel/" title="Legacy Motor Club Parts Ways with NASCAR Rookie Noah Gragson After Suspension; Mike Rockenfeller Takes the Wheel”>Hendrick Motorsports, a leading name in NASCAR.
Hendrick has established itself with record Cup Series wins and has been home to legendary drivers like Jeff Gordon and Dale Earnhardt, Jr., names that resonate even with those outside the racing community. Such triumphs stem from the combination of driving prowess and the superior craftsmanship of the cars, with a particular focus on the engine.
Tummond’s insight carries weight, as the trophy case at Hendrick proudly commemorates hundreds of victories, clearly outshining most facilities I’ve encountered with its abundance of grandfather clocks—awarded uniquely for victories at Martinsville Speedway. While much of the credit belongs to the drivers’ skills, Hendrick’s engine reputation is equally noteworthy.
Besides powering its own four teams, a multitude of racing teams lease engines from Hendrick, facilitating the operation of over 500 races annually. For a time, the aging machinery in the engine shop hindered both the design and production speeds due to the limitations it imposed. Thankfully, an investment in modern equipment not only alleviated these issues but also led to unexpected advantages that enhanced workflow within the shop.
The Driving Force Behind Engine Engineering
Crafting top-quality engines is crucial for maintaining Hendrick’s esteemed reputation. The engine shop does more than just cater to the four NASCAR teams it owns; it also provides engines for various other teams under the General Motors banner, a responsibility they take seriously. “We lease the same engine we utilize in our own cars,” Tummond emphasizes. “We want to ensure our customers never feel disadvantaged before the race even starts.” The engineering department at Hendrick continuously innovates and refines engine designs to uphold the highest achievable standards, a demanding endeavor that necessitates thorough quality testing and advanced machining capabilities.
Tummond remarks, “but we’d never revert.” The compact footprint combined with relatively large work envelopes made these machines ideal for the space available in the engine shop.

Post-installation, the machines exceeded the expectations of the team. “Grob claims six-micron accuracy, and it delivers without a hitch,” Tummond shares. “In the past, we had to struggle with tolerances. Now, if we instruct the Grob to cut a tenth, it does just that. We don’t need to do anything extraordinary to ensure it works.” Unexpected benefits also included significant time savings stemming from the machine’s superior kinematics and compact work envelope. “The difference in speed is astonishing. A machining task that took 15 hours is now completed in under an hour.”
While the shop may not be classified as high-production, the transition to a more modern line of milling machines allowed the team to focus more on refining engine designs for testing and alleviated the time pressure associated with preparing engines for races. However, some of the most significant advancements were made in the setup process.
Enhancing Setup Control
A notable change for the machinists was the shift to the Siemens Sinumerik 840D. Initially, the seasoned machinists expressed some reluctance to adapt to the newer controls, but they quickly became accustomed to the system. “The controls are incredibly precise and much easier than I anticipated,” says Jay Grubbs, a machinist and programmer at the shop. “The Dynamic Work Offset alone halved the setup time.”
Michael Tummond, the Engine Engineering Manager, operates one of the Grob 350A HMCs acquired by Hendrick Motorsports. Although there was initial hesitation regarding the Siemens controls, the machinists at the shop now praise the functionality and advancements provided by these features.
Dynamic Work Offset (DWO) serves as a feature that allows users to dramatically reduce the time required for zeroing the part. It modifies the machining program to correspond with the actual location of the part, thereby minimizing the necessity for manual centering. “Previously, we had to manually shim and attach end adapters to align with the program,” remarks Grubbs. With the implementation of DWO along with the Vero-S vise — a modular workholding system from Schunk that promises repeat accuracy of less than 0.005 millimeters — setup times have seen a significant decrease and manual shimming has become obsolete. “The first time we utilized the new control and fixturing, the setup was only off by 0.0001″ in one direction,” recounts Tummond.
This reduction in setup time has led to enhanced job satisfaction within the engine shop, alleviating the need for monotonous manual tasks and allowing machinists like Grubbs to focus more on creative projects. “Each time the engine designers innovate, we need to create a new program,” Grubbs explains. By dedicating less time to shimming parts, there is increased availability for programming toolpaths for groundbreaking engine designs, which not only adds value to the team but also makes the work more engaging for machinists such as Grubbs.
Although the continuous progression of incremental improvements may seem slow on a smaller scale, these advancements have culminated in the development of modern machine tools that offer remarkable precision and speed. Machinists accustomed to older models might question the necessity for high-tech solutions, yet the results are undeniable: significantly reduced setup and machining times, along with user-friendly programming that eliminates tedious manual labor from the workday. Such advantages can keep any shop operating efficiently.
