Design for Manufacture and Project Management Flashcards
List 3 things that successful planning of accurate and efficient manufacture of products requires
detailed design specifications facilitating testing throughout
evaluation of manufacturing accuracy required
clear production schedule
Give 3 pre-production QA procedures to ensure accuracy
CAD simulations
client feedback
production of templates, jigs and fixture
Give an example of 2 QC checks used in conjunction with client feedback for prototype production
visual aesthetics check
dimension check
Give 4 factors that the decisions made regarding the strategy for ensuring the accuracy of commercially produced products depend on
scale of production
particular manufacturing methods
types of products being made
skill level of workforce
Give 3 recommendations for small-scale production accuracy
great attention to dimensional accuracy - measuring devices such as callipers
templates
traditional tools require excellent hand/eye coordination
Give 2 recommendations for medium-scale production accuracy
extensive use of jigs and fixtures
highly accurate CNC machinery
strong reliance on high skill levels
Give 3 recommendations for large-scale production accuracy
sample testing during and after manufacture
effective machine tool maintenance
mould replacement cycle
Give 3 quality assurance procedures and policies to ensure products are ‘right first time and every time’
pre-production CAD modelling
rigid machinery and cutter maintenance schedules to maintain tolerances
FEA (finite element analysis) to analyse the effect of stresses
What are the 4 project management systems to improve to improve efficiency and reduce waste?
Total quality management
Scrum (agile manufacture)
Six Sigma
Critical Path Analysis
What does total quality management aim to do?
improve QA by harnessing workforce expertise
What is the scrum focus on?
use of workforce teams to respond quickly tosses in product design and manufacture
What is six sigma?
system for process improvement to reduce defects to fewer than 3.4 in every million
uses procedure monitors
5 Key Stages : DMAIC
D define issue
M measure extent of issue
A analyse where it occurs
I Improve by introducing rectification procedures
C control modified procedures through effective QA
What is a critical path analysis?
analysis of stages in project to ensure time-efficient completion:
sequential order of asks established
unnecessary waiting time identified
parallel processing opportunities exploited
What does the red line in a critical path analysis indicate?
minimum time (critical path)
What is quality control?
monitoring, checking and testing of QA tolerance conformity throughout production
