can use smaller tools without compromising material removal rates. This reduces tooling costs but the primary concern in this shop is reducing cycles. Roughing and finishing operations can often be completed with the same tool, reducing tool changes. Barron said that there have been significant improve- ments in the CAM software’s 3D Rest Roughing Toolpath. This toolpath typically generates a large number of trochoidal moves that get tools into tight spaces without overloading it. He has noticed that Mastercam has streamlined the code generated by this toolpath to reduce his computer’s memory overhead and provide a much cleaner code repre- sentation of the path during simulation. “It just runs faster because it doesn’t have to retract as much,” he said. “This has been very beneficial for reducing our programming time. The toolpath is also easier on the machine. Not a herky jerky, rapid here, a rapid there. It’s more smooth and continuous. It also gives us better finishes, which is something we take pride in.”
“It’s like a fire station here.
You have to be ready to go whenever the bell rings. On the other hand, it’s not cost effective to overstaff a fire station.”
(CAD/CAM Consulting Services) on an as-needed basis for support. CCC engineers answer questions by phone and email and visit the plant when asked to consult on more spe- cialized requests. In one instance the reseller helped expedite a project by digitizing a component for which there was no electronic model. HPD also relies on its reseller to provide training and to show associates how they might benefit from new or improved features in the latest version of the soft- ware. “Based on the dead- lines we deal with everyday, this service is invaluable,” Chase said.
No part is allowed to leave the facility until it has been inspected to assure
that it will fit on the chassis when it gets to the track. Quality Assurance, however, must not be a bottleneck in the manufacturing process. To prevent this, daily meetings are held with the Quality team so that they understand when a critical part will be completed and be ready to measure it immediately.
Process Documentation “We have two scenarios going on here simultaneously,” said Chase. “One is getting ‘panic Monday’ components out the door as fast as we can. We are also producing some very complicated components for ongoing development pro- grams. It is critical for us to document the process sequence of both scenarios to use for future reference. It is expected of our group to run a job the second time with greater efficiency than the first run. Without proper notetaking and document- ing, we will likely fumble around trying to figure out what we did the first run. Our process engineer rides along with the job to capture all relevant images and text for each of the jobs. He then compiles and creates a process manual which is stored in a HPD machine shop shared server. The next time the job comes around, we know exactly what we did before and we can do the next iteration even faster.” Honda Performance Development has a maintenance license of Mastercam so that they can call upon its reseller
Off To The Races Needless to say, the new Aerodynamic Package got shipped to the Ohio track to be used by the 12 racecars equipped with Honda engines. Those cars also posted the highest point totals that week. Was it the aerodynamic package that made the winning difference? “There are a thousand things that can happen between what we do and the guys crossing the finish line, but as far as team effort, we put in a strong team link at this side to be able to get them what they need and have it delivered on time,” Chase said.
What the HPD team can take credit for is improving its own on-time delivery performance. With typical lead times for critical parts of two to three days, this team has improved its performance metric from 89% to 95%. Chase believes there is more that his team can and will do to drive that metric even closer to 99+%.
