1 Manufacturing technology Introduction Technology II – Jan Tomíček
2 ManufacturingImportant part of World economy. Allmost all products are manufactured.Demands are increasingNew issues – energy efficiency, waste, etical issues
3 Changes in the world of goods manufacturing World wide competetionNew materialsAdvanced technologiesNew manufacturing systemsEnviromental issues
4 1. World Wide Competetion Global businessMarket = Whole worldEverybody can make business –knowledge vs. capitalcustomization vs. mass productionProduct placement vs. variability
5 2. New materials Demands from customers Smooth surface on plastic partsTransparency of plasticShiny metal look etc.New developed materials with better propertiesHeat resistant materialsHigh strength materialsSpecial materials
7 4. New manufacturing systems Manufacturing strategiesManagement
8 5. Enviromental issue Low energy and material consumption Utilization of human labor, heavy workHealt and security issuesEthical problems
9 Product Life Cycle Design Construction Manufacturing Sale Service and recycling
10 TIME Cost Per unit SATURATION Annual sales per model START-UP RAPID GROWTHMATURATIONCOMODITY or DECLINEProduct varietyGreat variety, product innovationIncreasing standartizationEmergence of a dominant stadart designHigh standardization„comodity“ characteristicsIndustry structureSmall competetiorsFallout and ConsolidationFew large companies„Survivors“ become comoditiesForm of competetionProduct characteristicsProduct Quality, Cost and availabilityPrice and Quality and ReliabilityPrice with consistent quality
11 Price of the product? What is the best price of the product? Smallest, affordable, highest, psychologically friendly, discounted??Production costs!
13 Manufacturing costs Methods: Casting, foundry, mouldingForming of metalformingMachining(material removal)Surface treatments(finishing)Heat treatmentJoining and assemblingMachining is approx 40% of manufacturing costsTECHNOLOGY II
14 MachiningChip removal process – Material is removed in form of chips from a piece of raw material to archive the desired shape.Material(chips) are removed by a tool from the blankThis process is called „Chip forming“
15 DISADVANTAGES ADVANTAGES variety of work materials variety of part shapes and geometric featuresdimensional accuracygood surface finishesDISADVANTAGESwasteful of materialtime consuming
