IENG 475 Manufacturing Operations
Agenda • Lab Schedule • Lab Planning • CAD – CAM Software • Manufacturing Background • Questions & Issues
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
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
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

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):
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!
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
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!
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
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
