MAE 277: Introduction to Mechanical Engineering Practice Fall 2012 Monday Marvel – CNC Machining

MAE 277: Introduction to Mechanical Engineering Practice Fall 2012 Sales and Production – Overview Which comes first, sales or production? 1.Sell first, then produce  Longer delay between sale and delivery  Allows customization of products by design firm  Allows companies not to produce large scale, high cost products until they are sold 2.Produce, then sell:  Little to no delay between sale and delivery  Customization of products must be done by customer  Companies must estimate initial production quantities and total  Have enough on hand  Pick appropriate manufacturing methods

MAE 277: Introduction to Mechanical Engineering Practice Fall 2012 Sales, Production, & Delivery – Influence on Design How do sales, production, and delivery influence product design? 1.What assistance is there to help customers choose?  Level of product variety and number of choices  Characteristics that customers base a decision on 2.How much can you train the consumer?  How intuitive must the product be?  How error tolerant must the product be? 3.How much time do you have for production? 4.What are your production capabilities?

MAE 277: Introduction to Mechanical Engineering Practice Fall 2012 Sales, Production, & Delivery – Influence on Design How do sales, production, and delivery influence product design? 5.What assistance is there to get the system online?  Does the product need to be fully assembled?  What setup time/effort is acceptable? 6.How is the product delivered to the final location?  Who delivers the product? User, delivery person, special delivery  Is the product in packaging or exposed?  Is the product fully assembled? Can it fit through doorways, go up stairs, etc.? 7.Where is the product delivered to?  What does the journey look like?  What are the environmental conditions?
