CMfgE study plan

CMfgE · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Manufacturing Processes

  • Map the CMfgE exam blueprint into a one-page table showing all four domains and their weightings, then allocate your 48 total study hours accordingly.

  • List the core traditional manufacturing processes (casting, forging, rolling, extrusion, machining, joining, sheet metal forming) and write a two-sentence purpose statement for each.

  • Define the key process-selection variables (material, lot size, tolerance, surface finish, cost per part) and rank them by influence on process choice.

  • Build a personal glossary of 25 manufacturing-process terms with definitions you write yourself, flagging any term you cannot define confidently.

Your checkpoint

A one-page blueprint map plus a 25-term self-written glossary covering Domain 1 fundamentals.

Week 2

Manufacturing Processes

  • Compute machining parameters (cutting speed, feed, depth of cut, material removal rate) by hand for at least six worked problems without looking at solutions first.

  • Explain how tolerance stack-up and surface finish requirements constrain process selection, using two contrasting part examples you invent.

  • Compare casting versus forging versus machining for the same hypothetical part on cost, strength, and lead time, and justify a recommendation in writing.

  • Summarize the main joining and assembly processes (welding families, bolting, riveting, adhesive bonding) and state one failure mode for each.

  • Draft 20 original practice questions on Domain 1 and answer them closed-book, scoring yourself.

Your checkpoint

A worked-problem set of six machining calculations plus a scored 20-question self-test with a written error log.

Week 3

Manufacturing Systems

  • Describe the components of a manufacturing system (people, machines, material handling, information flow) and diagram material flow for a simple job shop.

  • Calculate takt time, cycle time, throughput, and work-in-process for three numeric scenarios you construct yourself.

  • Explain push versus pull production, kanban sizing logic, and where each system fails, in a 300-word written summary.

  • Identify the seven classic forms of waste and give a manufacturing example of each that is not copied from a textbook.

  • Compare job shop, batch, and flow-line layouts on flexibility, utilization, and changeover cost.

Your checkpoint

A material-flow diagram with takt/throughput calculations and a 300-word push-versus-pull comparison.

Week 4

Manufacturing Systems

  • Explain OEE and compute availability, performance, and quality rates from a six-hour shift dataset you create.

  • Describe lean tools (5S, value stream mapping, SMED, standard work) and state the metric each one is meant to move.

  • Outline the role of MRP and ERP in production planning and distinguish dependent from independent demand with examples.

  • Summarize quality-system basics (SPC control charts, Cp/Cpk, root-cause methods) and calculate Cpk for one sample set.

  • Write 25 original practice questions spanning Domains 1 and 2 and complete them under timed conditions.

Your checkpoint

An OEE and Cpk calculation worksheet plus a timed 25-question cumulative test with a scored review.

Week 5

Additive Manufacturing

  • Distinguish the seven ASTM/ISO additive process categories and give one industrial application and one limitation for each.

  • Explain the AM workflow end to end: CAD, STL or equivalent file preparation, slicing, build setup, post-processing, and inspection.

  • Compare material extrusion, powder bed fusion, and vat photopolymerization on resolution, material range, build rate, and cost drivers.

  • Identify design-for-AM principles (support minimization, orientation, anisotropy, lattice use) and apply them to redesign one simple bracket conceptually.

  • List common AM defects (porosity, warping, layer delamination, residual stress) with their likely causes.

Your checkpoint

A process-category comparison matrix plus a written design-for-AM rationale for one redesigned part.

Week 6

Additive Manufacturing & Manufacturing Processes

  • Explain how AM changes process-selection economics at low, medium, and high production volumes, and state the crossover logic.

  • Describe qualification and inspection challenges for AM parts, including anisotropy, material certification, and non-destructive evaluation.

  • Summarize metal AM safety and feedstock handling concerns (powder handling, inert atmosphere, contamination control).

  • Revisit Domain 1 weak areas from your week 4 test and re-solve every missed question with a written explanation.

  • Write 20 original AM practice questions and answer them closed-book.

Your checkpoint

A volume-crossover cost comparison write-up plus a scored 20-question AM self-test and remediation notes.

Week 7

Smart Manufacturing

  • Define the components of a smart manufacturing architecture: sensors, edge devices, connectivity, data platform, analytics, and control layers.

  • Explain IIoT protocols and the difference between OT and IT networks, including why segmentation matters for security.

  • Describe how digital twins, condition monitoring, and predictive maintenance are applied on a production line, with the data each requires.

  • Summarize cybersecurity risks in connected factories and name controls that mitigate them.

  • Explain how analytics and AI support quality, scheduling, and energy management, and state one realistic limitation for each.

Your checkpoint

A one-page smart-manufacturing architecture diagram with annotated data flows and a short security-controls list.

Week 8

Manufacturing Processes & Manufacturing Systems & Additive Manufacturing & Smart Manufacturing

  • Assemble a weighted practice exam of 60 original questions (15 per domain) and complete it in one timed sitting.

  • Review every missed item and write the underlying concept, not just the correct answer, for each error.

  • Re-read your glossary and notes for all four domains and update any entry you can now state more precisely.

  • Build a one-page formula and definition sheet covering calculations you must be able to perform from memory.

  • Set a final-week review schedule that revisits your two weakest domains twice before exam day.

Your checkpoint

A scored 60-question timed mock exam with a written error analysis and a one-page formula sheet.

Milestones

Week 2: You can solve machining-parameter calculations and justify a process choice in writing without reference material, scoring at least 80% on your own 20-question Domain 1 test.

Week 4: You can compute OEE and Cpk from raw numbers and score at least 75% on the timed 25-question cumulative test across Domains 1 and 2.

Week 6: You can classify any described AM process into its category, name two limitations, and score at least 75% on the 20-question AM self-test.

Week 8: You score at least 80% overall on the 60-question weighted mock exam with no single domain below 70%, and your error log shows every miss traced to a named concept.
