Process Capability. Supplier shall produce a Process Capability Study which analyzes the information and data for the variable characteristics of all processes in a mutually agreed upon format. Supplier shall adjust processes as indicated by the Process Capability Study results to achieve targeted quality goals. Supplier shall develop X/R charts or comparable information to evaluate the capabilities of the processes. All critical dimensions or features of parts called out in Dot Hill's drawings shall meet a Cpk index of 1.33 (industry standard measurement).
Process Capability. For all process characteristics, Supplier shall perform process planning (work plans, test plans, operating supplies, tooling, machinery, etc.
Process Capability. (i) Supplier shall use statistical methods (e.g. SPC) to control the critical process parameters for its Process Capability: Cpk > 1.33
Process Capability. The supplier is responsible that the manufacturing process is conducted under controlled conditions. With regards to the principal of error prevention the supplier has to conduct a risk analyze for the manufacturing process (e.g. PFMEA). He is managing the potential sources of defects. Mainly these potential sources are: Set Up Process. Management of tool defects. Management of disruption within the manufacturing process Quality check before delivery. Incoming goods check after outsourced processes (e.g. heat treatment). The supplier evaluates his process with regards to systematic influences and disturbances that could result in systematic variances. The supplier is responsible for implement measures to optimize the process. The procedure to manage that kind of variances is described in the VDA Book 4. (Alternative the AIAG guideline SPC) If the supplier is aware that the requirements are not fulfilled, he is responsible to find the right measures to ship only o.k. goods.
Process Capability. Infortrend shall produce a Process Capability Study which analyzes the information and data for the variable characteristics of all processes in a mutually agreed upon format. Infortrend shall adjust processes as Infortrend determines necessary based on the Process Capability Study results to achieve targeted quality goals. Infortrend shall develop X/R charts or comparable information to evaluate the capabilities of the processes. All critical dimensions or features of parts called out in Dot Hill's drawings shall meet a Cpk index of 1.33 (industry standard measurement).
Process Capability. Supplier will demonstrate, through reasonable documentation of validation, a process capability (CpK) of 1.33 or greater on any Purchaser-identified critical characteristics, dimensions or attributes, as applicable and set forth in the Exhibits to this Agreement.
Process Capability. The SUPPLIER has to verify its production processes with the use of capability studies (machine capability Cm, Cmk, preliminary process capability Pp, Ppk, long term process capability Cp, Cpk) and R&R-Studies on the adopted inspection systems (repeatability and reproducibility). If the SUPPLIER realizes deviations from the agreed specification, it has to optimize its process, while containing the deviation with 100%-checks on product before delivery. The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine. The Cmk index is used to study the position of the machine’s capability in relation to the tolerance limits, which describes the capability corrected for position. It is not much use having a high Cm index if the machine setting is way off center in relation to the middle of the tolerance range. A high Cmk index means, then, that it is a good machine with a small spread in relation to the tolerance width, and also that it is well centered within that width. Cmk Index shall usually be ≥ 2,00 and shall be calculated considering a control chart with typically 50 consecutively produced parts per cavity. Different Cmk target or data collection process can be required by RÖCHLING based on OEM specification. Process Performance Index basically tries to verify if the sample generated from the process is capable to meet Customer CTQs (requirements). It differs from Process Capability (Cp, Cpk) in that Process Performance only applies to a specific batch of material. Samples from the batch may need to be quite large to be representative of the variation in the batch. An example of this is for a short pre-production run or a run@rate. Ppk Index shall usually be ≥ 1,67 and shall be calculated considering a control chart with 125 produced parts per cavity organized in subgroups of 5 parts each. Different Cmk target or data collection process can be required by RÖCHLING based on OEM specification. If the Index target is not met, products shall undergo a 100% inspection.
Process Capability. 10.1 Certificates of analyses (COA) and/or Certificate of Cleanliness (for tankers) and/or Certificate of Conformance (COC) (equipment and consumables) The supplier’s certificates will confirm that the raw materials/tankers/equipment/consumables meet the Distell specification. The certificate will contain the actual results obtained from testing and/or inspection performed as part of the quality control of an individual batch of the raw material and/or individual tanker/equipment/consumable. The minimum requirements for the certificate are drawn up per material category by Distell. IMPORTANT: ▪ The certificate should accompany every delivery note and be e-mailed to the relevant site Quality Manager prior to the delivery, or as otherwise agreed with the relevant Distell site. ▪ Agents, brokers and distributors are to ensure that all data requirements are met per source plant, and are ultimately responsible to ensure compliance to Distell specification and other requirements. Agents, brokers and distributors shall ensure that the approved source as well as the contact details of the agents, brokers and distributors are clearly indicated on the Certificate of Analysis. It is important that the specification limits reflected on the certificate are aligned with that of Distell. True values must be displayed on the certificate. The process capability demonstrates the repeatability and consistency of the supplier’s manufacturing process relative to Distell’s requirements, in terms of specification limits per the set parameters. Process capability assumes that the process is centred on the target value (aim specification). Process capability measures process variation with respect to the allowable specifications and consider the location of the process average. Distell expects all the suppliers to have the necessary process measurements in place to detect process deviation, in order to rectify proactively. Process control measures should be able to demonstrate quality consistency and allow the prevention and/or removal of non-conforming material prior to the delivery to Distell. Distell requires the supplier’s compliance to a process capability of Cpk >1.33 for each parameter. Suppliers that cannot meet the stipulated process capability and can substantiate it with good reason(s), may apply for exception for that particular material parameter at Distell Supplier Quality Management, where after an investigation will be launched by the relevant Supplier Development ...
