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

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!

21. 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

22. Reasons for Automating
IENG 475: Computer-Controlled Manufacturing Systems
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!

23. Reasons NOT to Automate
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
