Frequently Asked Questions
What is the CMfgE certification?
The Certified Manufacturing Engineer (CMfgE) is a professional credential issued by SME (Society of Manufacturing Engineers) that validates broad competency across all areas of manufacturing engineering. It covers manufacturing processes, automation, materials, quality, production planning, and emerging technologies like Industry 4.0.
What are the eligibility requirements for the CMfgE?
CMfgE candidates need a combination of education and manufacturing experience totaling at least 8 years. A bachelor's degree in engineering counts as 4 years, an associate's degree as 2 years. The remaining years must be verifiable manufacturing engineering experience. A master's degree can count as 5 years.
How hard is the CMfgE exam?
The CMfgE is considered a challenging exam with an estimated 50-60% first-time pass rate. It covers a very broad range of manufacturing topics, requiring knowledge across processes, materials, quality, automation, and management. Most candidates study 150-200 hours over 3-6 months. The breadth of content is the primary challenge.
How long does CMfgE certification last?
CMfgE certification must be renewed every 3 years. Renewal requires 30 professional development points (PDPs) earned through continuing education, publications, presentations, patents, or other qualifying activities. There is also a renewal fee. If certification lapses, the candidate must retake the exam.
What is the difference between CMfgE and CMfgT?
CMfgE (Certified Manufacturing Engineer) is the engineer-level credential requiring 8+ years of combined education and experience. CMfgT (Certified Manufacturing Technologist) is the technologist-level credential requiring 4+ years. CMfgE covers more advanced topics and is considered the higher credential. Both are issued by SME.
What study materials are recommended for the CMfgE?
Recommended study materials include the SME Manufacturing Engineering Body of Knowledge (MEBoK), the Tool and Manufacturing Engineers Handbook (TMEH), Fundamentals of Manufacturing by Philip Rufe, and SME's online learning resources. Practice questions and study groups are also highly recommended due to the exam's breadth.
