workpiece specifications: 1 Bearing at each
end, 1 gear, 800
mm length
Workpiece material: Stainless steal.
Production quantity (EA/year) : 170.000
Objective: Maximum efficiency
PROBLEM: You are a Manufacturing Engineer in the "Super Machining Factory". You have the responsibility of manufacturing a part that can be manufactured on a lathe machine and should have at least following specifications (as given individually). The factory will build a new shop in order to manufacture this part only. Find/calculate the followings according to your given individual conditions: 1. Calculate all the machining operations according to your individual conditions such as minimum cost, maximum productivity, maximum efficiency. 2. Define the Lathe Machine Specifications and select one from the market. 3. Define the machining parameters such as cutting speed, feed rate, depth of cut, angles etc. occurred during cutting for each operation. 4. Select the cutting tools and calculate the tool life, cutting temperature etc. 5. Calculate all the forces occurred in the shear and friction zones. Find cutting and tangential forces. 6. Find the production cost per part and advice the amount of benefit (sale price) and find the yearly gain. 7. List all the calculated/selected/found parameters in a table and make a final comment. GIVEN: Operator's wage: 1.100$/ month Operator\&Machine Overheads: 185% and 175% respectively Machine Amortization Period: 12 Years Please assume/select or find appropriately any other unknown which is not given required for the solution.
