PFMEA Training By TONEX, Process FMEA Training
PFMEA Training, Process Failure Mode Effects Analysis (PFMEA) Training Course Description
PFMEA training, Process FMEA training course will cover the theory, logic, and techniques behind the process failure mode and effect analysis procedure.
What is PFMEA?
A Process Failure Mode Effects Analysis (PFMEA) is a systematic analytical methodology adopted by an organization, business department, or Cross Functional Team (CFT) in order to assess the potential causes of failures in a process. PFMEA is a useful tool to determine the effect of the failure, and evaluate and prioritize the reduction risk actions. Process FMEA is used when a new product or a new process is designed. PFMEA is a practice in which the engineering team evaluates all the possible causes for failure. Such methodology is often applied at early stage of the process or product development, however it can be beneficial in the daily basis improvement and problem solving. PFMEA assesses each step of a process and assigns a score of 1 to 10 to its following variables:
- RPN (Risk priority number)
TONEX PFMEA training course will teach you what each of the above variable means and they are measured by PFMEA. Also TONEX PFMEA seminar will help you learn a general template for this procedure, while also teach you how to tailor it based on your product/process specifications. Students will bring their own examples and using Tonex PFMEA framework and tools, they are able to analyze their process and measure the failures and risks while in the class.
During this two-day hands-on seminar, trainees will also learn about the PFMEA applications in the following matters:
- Problem-solving process
- Daily improvement
- Creating value-added PFMEAs in a shorter time
- Identifying operator errors in PFMEA
When using in problem-solving PFMEA demonstrates multiple similarities with Eight Disciplines of Problem Solving (8D) method. During the TONEX PFMEA training course, we will explain the relationship between PFMEA and 8D methods and will teach you when to use which.
As mentioned above, PFMEA is used on early stages for initial improvements. However, TONEX PFMEA seminar will train you how to put this practice into work for your day-to-day improvements also. Once it is used effectively by a Cross Functional Team (CFT), PFMEA can continue its service to Kaizen or Continuous Improvement teams.
Another benefit of participating in TONEX PFMEA training course is that you will learn the techniques to dramatically shorten your PFMEA Development activities. Such action occurs through reviewing all the available data and identifying areas in which the information is new, changed, or affected by the time and environment. During the TONEX PFMEA workshop, we will train you to capture known and brainstormed failure modes and causes in a user-friendly worksheet.
Those who have the experiencing of developing PFMEAs can tell you that it is not an easy task. A comprehensive PFMEA Development is crucial in order to gain value from practice, while it should not be an excessive time intensive procedure. The TONEX PFMEA seminar will provide you the techniques which help you create a comprehensive and effective PFMEA at a reasonable amount of time. We will teach you how to collect and document all the brainstormed and received information into a database so that if the same problem happens, there won’t be any need to have a discussion and brainstorming session again. Through this useful technique, failure modes and causes can be reviewed fast to develop a proper PFMEA.
Learn about Four Common Classes of FMEA:
- System FMEA: Focuses on how interactions among systems might fail.
- Design FMEA: Focuses on how product design might fail.
- Process FMEA: Focuses on how processes that make the product might fail.
- Machinery FMEA: Focuses on how machinery that perform processes might fail.
- Process Failure Mode & Effects Analysis (PFMEA) Operating Scope :
- Processes involved in determining of final product characteristics.
Trainees Will Also Learn:
- How to incorporate PFMEA into new product development process
- How to impress customer and meet organization requirements
- Relationships between PFD, PFMEA, Control Plan, SOP
- Relationship between PFMEA and 8D
Based on the effects of failure mode, the attendees will identify the severity of the failure mode by using severity-ranking chart:
- PFMEA Input for Preparation
- Process Flow Diagram
- Drawing & DFMEA
- AIAG FMEA manual 4th edition as guideline standard for PFMEA preparation.
- PFMEA check sheet for carrying out the PFMEA.
- Historical data (e.g. Customer Return / Warranty Rejection, In-house Rejection, Process Capability Report etc)
- Quality and Reliability History
- Occurrence matrix and feedback ratio
- Approach for making PFMEA.
- Identify the potential failure mode of each process and find out the effect of each potential failure mode at the current operation, next operation(s) and at customer end.
- Lesson learned
- PFMEA Output
- Detection Rating
- Occurrence Rating
- Severity Rating
- RPN Rating
- Prevention Method
- Detection Method
- Recommended action, as applicable
- Risk Evaluation
- Risk priority number (RPN): Risk Priority number is Severity multiplies by frequency and detection. The use of an RPN threshold is NOT a recommended practice for determining the need for actions.
- Setting of RPN target
- RPN target will be fixed based on the Severity ranking for initiating action on failure mode / causes. The following RPN Target will be used during PFMEA unless otherwise specified by the customer.
Example approaches to reduce S,O, and D:
- To reduce Severity (S) ranking: Only a design or process revision can bring about a reduction in the severity ranking.
- To reduce Occurrence (O) ranking: To reduce occurrence, process and design revisions may be required. A reduction in the occurrence ranking can be effected by removing or controlling one or more of the causes of the failure mode through a product or process design revision.
- To reduce Detection (D) ranking: The preferred method is the use of error/mistake A redesign of the detection methodology may result in a reduction of the detection ranking.
Examples of Weld Process Failure Modes
- System (Welding Line)
- Robot Failure
- Loss of Incoming Water
- No Signal to Weld
- Subsystem (Weld Gun)
- Cracked Jaw
- Failed Servo Motor
- Failed Shunt
- Component (Servo Motor)
- Loss of Position
- Premature Seal Failure
- Cost of Defects
- Risk of Defects
- Bracketing Strategies
- Protecting On-Time Delivery
- Cost of Stopping Production
- Cost of Recall Campaigns
- Benefits of Traceability
- Prioritization of Risk
Alternative strategies exist for the mitigation of risk, for example:
- High Risk Priority Numbers
- High Severity Risks (regardless of RPN)
- High Design Risks (Severity x Occurrence)
- Other Alternatives (S,O,D) and (S,D)
TONEX Process FMEA training includes many in-class activities including hands on exercises, case studies and workshops. During the Process FMEA workshops, students bring in their own design work and issues and through our coaching, develop their own Process FMEA Failure Mode and Effects Analysis (PFMEA).
Learn about the framework, tools and procedures:
- Potential FMEA Reference Manual is the authoritative reference.
- Severity scores of 9 or 10 must be used for safety related risks.
- Occurrence ranks how often each cause is likely to result in failure.
- It is appropriate to focus on high severity items first.
- Credit for preventive actions shows up in the frequency of occurrence.
- Risk Priority Numbers provides a rank order to risks and action items.
- An effective approach is to continually focus on the top five concerns.
- Process FMEA should result in tangible improvement to process
