Gauge Repeatability & Reproducibility (GR&R) in MSA
Measurement system accuracy (MSA) can be defined as the capability of a measurement system to measure with high accuracy and precision (Gage Repeatability & Repeatability). An MSA is one of the major key elements of the PPAP (Production Part Approval Process) and is an integral part of the process. It is a statistical tool that allows one to obtain information about the quality of data by analyzing the measurement system. As a result of this statistical tool, you will be able to determine the accuracy of the measurement, and this will help you identify the error in either the instrument or the appraiser. Gauge Repeatability & Reproducibility (GR&R) The repeatability of a measurement is the amount of variation in measurements that can be obtained with a measurement instrument when it has been used several times by the same appraiser. In this case, the same characteristic must be measured while the same part has the same characteristic. It is common to refer to repeatability as equipment variation, and it is the most common cause of variation in successive trials under defined measurement conditions, as well as in successive experimental conditions. The term reproducibility is used to describe the variability between appraisers when it comes to appraisals. Generally, reproducibility is defined as the variation in the average of measurements made by different appraisers using the same measuring instrument and using different methods of making the measurements. In this case, the same characteristics are measured on the same part in the same way. This is often true for manual instruments influenced by the operator’s skill. It aims to accomplish the following objectives: An assessment of how much error is present in the measurement as a result of the measurement process itself will be done. Measure the variability of the measurement system and quantify it. This is applicable to both attribute data and variable data. It is used on the critical inputs and outputs prior to collecting data for analysis.Conducting MSA reduces the likelihood of passing a bad part or rejecting a good part. In the MSA GR&R study, repeatability and reproducibility are used to evaluate the accuracy of a gauging instrument. The technique includes taking a chain of measurements to certify that the output is the same value as entered. Furthermore, it is required that the same measurements be acquired under the same operating conditions over a defined period, under the same conditions. Each type of Gauge R&R study has a different objective. In gauge R&R, types may vary depending on the availability of data and types of tests, such as destructive and non-destructive tests. Crossed Gauge R&R: A crossed study is the most general sort of Gauge R&R look at is most usually used when we can able to instruct every appraiser to measure every element in a fixed wide variety of times. And additionally, it is utilized in non-destructive situations when parts are non-destroyed throughout the measurement and may be measured two to three times with the same part. This study can be conducted only for variable gauges and not used for attribute gauges. Nested Gauge R&R: This method is used for destructive type parts because the test will destroy the part. In this method, only one appraiser measures every part. One of the problems in nested Gauge R&R is to perceive a batch of produced parts that is so close to the authentic that it reasonably may be assumed the components within the batch are the same component. The important thing to being able to run destructive Gauge R&R examination is the assumption that a batch is homogeneous. But if we can handiest capable of achieving two similar components at a time then each appraiser must measure different parts. In this example we need to deal with the facts very differently and use a nested have a look at in which each appraiser measures a unique group of parts. Expanded Gauge R&R: Expanded Gauge R&R study is used when we need to consider more factors than appraiser and part. In general crossed and nested Gauge R&R study deal with only two factors (Operator and part). In theory, we should consider only these two factors. But other factors may also play a major role in Gauge R&R study. As an example, environmental elements which include temperature and humidity are crucial for laser-based units, and ambient light will be tremendous for non-contact scanning. ComplianceXL’s supplier verification process includes validation of the MSA, ensuring that only accurate results are used in the PPAP.

FAQs: 1.What is the significance of GR&R in MSA, and why is it so important? A measurement system’s capability and reliability can be determined by GR&R. GR&R ensures accurate and consistent measurements by assessing repeatability (consistency) and reproducibility (agreement). Making informed decisions based on measurement data and maintaining quality control is crucial. 2.In what ways might GR&R vary from one region to another? Measurement results are affected by several potential sources of variation in GR&R analysis. Among them are equipment variability, operator technique, environmental conditions (temperature, humidity, etc.), part placement and alignment, measurement resolution, and operator-gauge interaction. Identifying and minimizing these sources of variation improves measurement system reliability.
An overview of the requirements for PPAP submission
Business needs to streamline processes to develop and manufacture products, and one way to do that is by submitting Production Part Approval Process (PPAP) documents. PPAP documentation is used to demonstrate that the supplier understands the customer’s engineering design records, specifications, and related processes. It also shows that they produce parts or components in accordance with those specifications. Manufacturers need to provide print samples, data-related drawings, such as 3D CAD files or CAM files, as well as other essential documents such as Quality Control Plans (QCP), Process Flow Diagrams (PFD), Control Plans (CP), Capability Studies (CP/CPK), Key Characteristics Listings, etc. It is also possible to review existing suppliers periodically by leveraging the information from previous submissions. PPAP submissions require detailed specifications including part and assembly drawings, process flow diagrams, production control plans, and gauging instructions. Additionally, quality assurance techniques and reliability data are required to demonstrate that all downstream activities related to their product have been adequately validated or verified. A failure mode effects analysis (FMEA) must also be conducted before proceeding to the manufacturing stage to identify potential problems with the design. Lastly, prototype inspection reports must be submitted for each stage prior to the completion of the PPAP-4. This report is then submitted by the supplier at the time of contract execution, capturing the details of the stocking agreement. PPAP submissions include a Product Part Approval request form, drawings that illustrate all necessary characteristics and special characteristics with appropriate tolerances, a process flow diagram of production processes, and a master record of each service or product. Additionally, sample inspection reports are required illustrating incoming inspections of purchased parts, dimensional results from initial production part approval testing, and engineering drawing records. In addition, validation test reports will demonstrate all aspects of the product follow the customer’s specifications and requirements, as outlined in the control plan including the design FMEA. Finally, PPAP packages must include capability studies that provide evidence of continuous process stability over time. 18 Key Elements of PPAP Process for Automotive Industries Design records Engineering change documents Customer engineering approval Design FMEA (Design Failure Mode and Effects Analysis) Process flow diagrams Process FMEA (Process Failure Mode and Effects Analysis) Control plan MSA (Measurement System Analysis) Dimensional analysis Material performance results Initial process studies Qualified laboratory documentation ARR (Appearance Approval Report) Sample product Master sample Checking aids Records of compliance PSW (Part Submission Warrant) To ensure that their document package is complete, companies need to understand their process from supplier to customer.

Key Elements of PPAP Process for Automotive Industries
The Production Part Approval Process (PPAP) acts as a proof for the supplier to understand the detailed requirement of the product/part being manufactured or supplied to its customers. The PPAP consists of 18 elements or documents that detail out the production process: Design Documentation: The design records for components and/or details of the saleable product/part. In case the design record is in the electronic format (for example, CAD / CAM math data) the organization shall produce a hard copy (for example, pictorial, GD & T sheets, drawings etc.) to identify the measurements taken. Engineering Change Documentation: It is a document that shows a detailed description of the change. The document records or authorizes the change to a specific design. The reason for the change is also recorded. Typically, this document is called the “Engineering Change Notice”. It may be covered by the customer Purchase Order (PO) or any other engineering authorization. Customer Engineering Approval: The organization shall have evidence of customer engineering approval, as specified by the customer. The customer engineering approval may be required for the product or any associated documentation related to that product. If approval is required, it will be stated on the customer’s drawing or any similar documentation. When required as part of the PPAP, the supplier must provide evidence of approval by the customer engineering department. Design Failure Mode and Effects Analysis: The organization responsible for the product design shall develop a DFMEA in accordance with, and in compliance to, the requirements specified by the customer. A single DFMEA may be applied to a family of similar parts. Design Failure Mode and Effects Analysis (DFMEA) is a cross-functional activity that examines design risks. It explores the possible failure modes, effects on the product/customer, and the probability of failure to occur. These failure modes include: Product malfunctions Reduced performance or product life Safety and regulatory issues. The DFMEA is a document that should be reviewed and updated throughout the product life cycle. There are 11 steps required to complete a DFMEA, Design review – Use the product or service design drawings or documents to identify each component and its relation with other product/service components. Brainstorm upon the potential failure modes. List the potential failure modes. List the potential effects of failure mode. Assign the seniority ranking, basis the consequences of failure (1-10). Assign the occurrences ranking (1-10) Assign detection ranking based on the chance of detection prior to failure (1-10). – Easy detection is assigned a score of -1 or less – Difficult detection is assigned a higher score Calculate the Severity X Occurrence X Detection (SOD) number or the Risk Priority Number (RPN). Develop an action plan to reduce vital RPN (above the set base line). Implement the identified improvements. Calculate the RPN, basis the improvements. Do mistake proofing. Process Flow Diagram It is a visual representation (diagram) of the entire process – from receiving through shipping – including the external processes and services. The main objective or purpose of the Process Flow Diagram is to help people “see” the real process map. It can be used to understand the following characteristics of a process: Systematic process linkage Offline activities (measurement, inspection, handling) Rework, scrap, etc. When to use a Process Flow Diagram? To understand how a process is done Before completing the FMEA. Process Failure Mode and Effects Analysis PFMEA is used to identify and prioritize risk areas and their mitigation plans. A cross-functional team (CFT) should complete the PFMEA. Objective or Purpose: Identifies potential failure modes, causes, and effects. Inputs are drawn from the process flow diagram. Identifies key inputs that affect quality, reliability and safety of the product or process – either positively or negatively. When to use PFMEA: After completion of process flow diagram. Prior to tooling for production. Benefits of PFMEA: Allows users to take a proactive approach to what can go wrong in a process and manage risks better. Promise: You own/operate/require/design or are responsible for equipment essential to a system/process/activity, which may be small or large, simple or complex. It may be related to a plan or something that’s currently in operation. Control Plan The organization has to maintain a control plan as per customer –specific requirements. If the organization reviews commonality, then control plans for families of products are acceptable. Approval of control plans may be required by some customers. The organization shall have a control plan that defines all methods used for process control; it should comply with all customer specific requirements. The control plan for families of parts is acceptable if the new parts have been reviewed for commonality by the organization. In general, there are 3 types of control plans: Prototype Pre-Launch Production The pre-launch and production control plans may be applied to a family of products or specific processes. Measurement System Analysis Studies MSA is a statistical tool used for determining if a measurement system is capable of returning precise measurements (Gage Repeatability & Reproducibility) or not. Objective or purpose: To determine errors in measurement due to the measuring process itself. Quantify the variability added by the measurement system. It is applicable to attribute data and variable data. Conducting MSA reduces the likelihood of passing a bad part or rejecting a good one. It is used on critical inputs and outputs, prior to collecting data for analysis. Dimensional Results: It provides evidence that dimensional verification is complete and the results indicate compliance with specified requirements. Objective or Purpose: To show conformance to the customer’s print (drawings) of dimensions and all other noted requirements. It is used for each unique manufacturing process (for example, cells or production lines, and all moulds, patterns or dies). Records of Material / Performance Tests: Material Tests: The supplier needs to verify and test all parts and products for the chemical, physical, or metallurgical requirements of materials, as mentioned in the drawing or control plan. For products with customer developed material specifications and/or customer approved supplier list, the supplier shall procure materials and/or services from a supplier mentioned on
