Engineering Manufacturing Facilities

2. 22 Engineering Manufacturing Facilities

3. Objectives List the major engineering tasks in organizing a manufacturing operation. Describe how the manufacturing engineer performs these tasks. Demonstrate the use of forms such as the operation process chart and the flow process chart.

4. Engineering Manufacturing Facilities • Engineered facilities • Permit efficient production • Manufacturing engineers • Design and develop facilities for approved products • Allow production at a competitive price

5. Selecting and Sequencing Operations • Plant engineering • Deciding needed processes (selecting) • Putting them in order (sequencing) • Manufacturing engineers organize with • Forms • Methods

6. Operations Sheet • Engineers must analyze the product drawings to determine needed operations • Operations sheetincludes: • Operation name • Machines needed • Tooling needed

7. Additional Forms • Aflow process chartallows engineers to: • Study the sequence of operations • Identify the best ways to make a part • Uses industry standard symbols

8. Flow Process Chart Describes the tasks Provides code numbers for each task Identifies machines Lists tooling needed for the task Does not let you view the whole system

9. Flow Process Chart (Cont.)

10. Operations Process Chart • Shows the whole system for the product • How each part is made • How they are assembled • Where operations and inspections fit in • Used in scheduling production • Allows engineers to analyze the overall manufacturing process

11. Operations Process Chart (Cont.) • Tasks not included: • Transportation • Delay • Storage

12. Designing Tooling • Tooling is designed to increase the operation’s: • Speed • Accuracy • Safety

13. Preparing Plant Layout • Resource flow • Manufacturing engineers plan • Machine placement • Material movement • Utility location • Aisles

14. Plant Layout • Process layout • Custom manufacturing • Intermittent manufacturing

15. Plant Layout (Cont.) • Product layout • Continuous manufacturing

16. Communicating Layouts • Manufacturing engineers must document and communicate their designs • Plant layout drawings • Models

17. Material Handling • Fixed path devices move a product from one fixed point to another • Assembly lines • Conveyors • Pipes • Elevators • Chutes

18. Material Handling (Cont.) • Variable path devices move product in a number of different directions • Forklifts • Overhead cranes • Tractors • Hand trucks • Require an operator

19. Improving Manufacturing Systems Production lines redesigned and improved More efficient machines and tooling Better material-handling devices Improved material flow Operations refined

28. Review Question True or False? Process layouts group machines by the processes they perform. True

29. Review Question True or False? Variable path devices move a product from one fixed point to another. False

30. Glossary • Competitive price • a price at which a product can be produced cheaply enough to sell at a price similar to like products on the market. • Flow process chart • a graphic means of showing all the steps and processes a single part goes through as it is manufactured. • Manufacturing engineer • a professional person who organizes manufacturing operations.

31. Glossary • Material handling • the methods used to move material around a manufacturing plant. • Operations • the processes that shape and assemble a product. • Operation sheet • a form used to record the sequence of operations needed to produce a product. • Process layout • a type of plant layout where machines are grouped by the process they perform.

32. Glossary • Product layout • A manufacturing arrangement in which equipment is arranged in the sequence of operations needed to produce the product. • Resource flow • the flow of materials and people inside a plant. • Tooling • devices such as jigs, fixtures, patterns, and templates that help workers make products better and faster. Tooling is designed for three purposes: to increase speed, accuracy, and safety.
