  1. IENG 475 Manufacturing Operations

  2. Agenda • Lab Schedule • Lab Planning • CAD – CAM Software • Manufacturing Background • Questions & Issues

  3. Lab Schedule • 1st Lab Tues, Jan 15 – Safety Theory – Mfg Eng Lab • Review Lab assignment from Schedule Page • Meet in MFG ENG Lab (need to start labs on time) • Take notes during lab in LAB Engineering Notebook (everyone) • Lab assignments (1 per team) – usually due next lab • brief summary and documentation of design/exercise • short answer to questions (if any) • copy pages from everyone • 5S at end of each lab • Primary result of lab exercises is to complete project • Open Lab times as necessary (e-mail for appointment) • Open class and lab periods reserved at end of term (2 weeks) • Use Finals Week for project documentation & demo

  4. Five processes (plus assembly) needed to produce project Laser Engraver CNC Mill CNC Lathe CNC Router(s) 3-D Printer(s) Drill Press (Single-cycle Automatic / Manual) Miter Saw & Sabre Saw (Must use both) 5 in 1 Machine (Table Saw / Sanding) Stock Wood (Red Oak, Ash, MDF) Plastic (ABS, Acetal, Acrylic, PLA) Leather Tile Purchased Material Clock Mechanism, Hinges, Magnets, Stock, Stain, Paint … Lab Capabilities / Project Req’s

  5. Laboratory Software • SolidWorks • This software will model the solids you need for project • We need to follow certain lab conventions for production • MasterCAM for Solidworks • This software will help create process plans for project • Speeds up the generation of CNC code, greatly! • May load SolidWorks & MasterCAM for SolidWorks on yours • See links on Materials page • Takes about 1-1/2 hours – best done from Lab jump drive during a lab • Might only work from MFG ENG Lab • Could try to VPN into SDSM&T • Does work from Collaboration Space, Design Studio • May load MakerWare on any capable computer • This software will let you orient and control the 3-D printers

  13. Manufacturing Operations • What competitive trends exist? • Where are products being made? • What kind of products are being made at these locations? • How are products being made at these locations? • What is the basis for manufacturing competitiveness? • Competitive Advantage(s):

  14. Levels of Automation • Manual Production – using single station manned cells operating independently • Automated Production – using single station automated cells operating independently • Automated, Integrated Production – using multi-station automated systems with automated material handling The appropriate level of automation is situational – there is no universal best answer!

  15. Manufacturing Operations • Mfg Plant Limitations & Capabilities: • Technological Processing Capabilities • Physical Production Capabilities • Production Capacity Limits • Conditions for Appropriate Automation: • Predictable, stable / expanding market • Need to satisfy business objectives of firm • Technology must be available at the right: • Performance • Cost • Maturity

  16. Reasons for Automating • To increase labor productivity • To reduce labor cost • To mitigate the effects of labor shortages • To reduce or eliminate routine manual tasks • To improve worker safety • To accomplish processes that cannot be done manually • To improve product quality • To reduce manufacturing lead time • To avoid the high cost of not automating … when you could have!

  17. Task is too technologically difficult to automate Product life cycle is too short Product is too customized Product demand is too variable To reduce the risk ($) of product failure To deal with these aspects, use the USA Principle: Understand Simplify Automate Reasons NOT to Automate

  18. Ten Strategies for Automation and Improvement • Specialization of Operations • Combined Operations • Simultaneous Operations • Integration of Operations (drill 6 holes vs 1) • Increased flexibility (CNC Operations) • Improved material handling (ASRS, kitting) • On-line inspection (visual scan circuit boards) • Process Control (mag 7, SPC, exp. Design) • Plant operations control • Computer Integrated Manufacuting
