Summit Manufacturing Systems
Our mission at Summit is to help manufacturing companies create stable, repeatable processes that save time and money. Unlike traditional machine tool or gauge suppliers, we are a service-based business that focuses on the total solution rather than making a sale. Summit will always recommend the best technology for the job even if it is not a product we represent directly. We specialize in turn-key systems that are designed and engineered to meet any unique challenge; Our job is not finished until results are produced and the customer is satisfied. http://www.summitmfgsystems.com
Products/Services Inspection and Quality Services
• A team of 4 CMM programmers with 30+ years’ experience (Zeiss calypso, Modus, MCosmos, MeasureMax, Polyworks, etc.) • Former Quality Managers, Lean Six Sigma Blackbelts and machinists o We have worked on the shop floor and have firsthand experience equating quality inspection programs with time and money saved. • First time yield of a program through a GRR we expect 10-15% not to pass the customer tolerances. To avoid this costly study, we first run a type 1 study to look at Repeatability of the program (single part, in a fixture not moving, program run multiple times) This can identify issues that need to be fixed before the time is spend running 90 parts. • An iterative process is used to run the GRR with only the features failing needed to be run a second or third time with different methods used. This draft of the program will use two or more methods for the features in question. In this way time is saved on the GRR and money. • Future programs written for the same customer that have similar parts we DO NOT recommend a full 10x3x3 study. Once the program methodologies have been proven and documented a short form of the GRR is acceptable to prove reproducibility of the fixturing and repeatability of the program. We suggest a 5-10 part sample with one operator loading and unload each part randomly. If this test produces any unacceptable results a full study would be performed. • We understand and use GRR studies to our advantage. We look at the % tolerance of the study and the capability of the process Cp. This way tolerances bands can be off set to ensure a capable process without having to spend a fortune on new inspection equipment. • We know that GRR doesn’t prove accuracy of the machine. This is set through calibration. This can also be looked at by measuring a known part and looking at the bias. • Because CMMs are kind of a black box, if we can reproduce the measurement with traditional gauges this helps to win over the shop floor. We like gauge blocks and pin to verify sizes and if needed a mic for a quick sanity check.
