Machining economics encompasses a range of models and scenarios aimed at enhancing the effectiveness and efficiency of machining processes. It involves optimizing the overall outcome of a machining process. At a micro-technological level, this means maximizing tool life, increasing the number of workpieces produced per cutting edge, adhering to pre-defined cycle times, minimizing tooling costs,…
Engineering economics might sound boring, but trust me, understanding the costs of success is crucial for any engineer or entrepreneur. Essentially, engineering economics is about creating, estimating, and assessing economic results when there are different options to achieve a specific goal. Some universities require engineering economics as part of undergraduate programs. This subject also appears…
The expansion plans of Acme Granite, Stone & Brick call for the company to add capacity for a new product in 5 years. The company wants to have $360,000 available before it announces the product. If the company sets aside $55,000 now and $90,000 in year 2, what uniform annual amount will it have to…
For the cash flows below, find the value of x that makes the equivalent annual worth in years 1 through 7 equal to $300 per year. Use an interest rate of 10% per year. Show solutions ( a ) by hand and ( b ) using the Goal Seek tool. Sample problems and notes are…
Costs associated with the manufacture of miniature high-sensitivity piezoresistive pressure transducers are $73,000 per year. A clever industrial engineer found that by spending $16,000 now to reconfigure the production line and reprogram two of the robotic arms, the cost will go down to $58,000 next year and $52,000 in years 2 through 5. Using an…

Civil engineering consulting firms that provide services to outlying communities are vulnerable to a number of factors that affect the financial condition of the communities, such as bond issues and realestate developments. A small consulting firm entered into a fixed-price contract with a large developer, resulting in a stable income of $260,000 per year in…
