05 - Fundamentals Of Production Systems Flashcards
What are the two parts of the work preparation phase?
1) process planning
2) work system design
Name the 5 branches of production and point out their connection with a diagram!
Product design
- > work planning
- > production control
- > manufacturing
- > assembly
Name two examples for each kind of planning tasks according to long-term, medium-term and short-term task!
Long-term: 1) material planning 2) process planing Medium-term: 1) planning preparation 2) cost planning Short-term: 1) handle part list 2) NC-programming
Production control is influenced by lots of various factors
1) product range
2) production type
3) stockage
4) product structure
Various task have to be fulfilled during the manufacturing and assembly process. Name 3 tasks for each of the two processes!
Manufacturing tasks: 1) tool change 2) processing 3) work piece change Assembly tasks: 1) joining 2) handling 3) adapt
Name 3 advantages and disadvantages of the kanban system
+ low inventories
+ minimal control effort
+ reduction of throughput
- low buffers lead to a breakdown of all subsequent production processes in case of failures
- highly unsteady production volumes are not controllable
- low number of variants/high number standardized parts requied
What are the advantages of the one-piece-flow? List 3 of them!
1) reduced throughput time
2) minimum stocks in the lines
3) visual management
There are two completely different ways to organize production and to release production orders. Name them and assign Kanban and Heijunka to the right principle!
1) push principle: (Heijunka)
One control unit orders demands to each station individually
2) pull principle: (Kanban)
A production order is provided to the last step of the production
Describe the two steps of Heijunka!
1) leveling total production volume into daily volumes
2) smoothing out production
