In today& / #8217 / s life, companies are faced with the problem of providing quality
goods and services at competitive prices. Cost estimation is a very important
process for a forging company, as each time a quote is sent to a customer, the
company earns or loses money depending on the results of the particular
estimate. However, determining pricing for customer quotes is a matter of time
consuming, detailed number of tasks repeated each time. Cost estimation
software might do those tedious calculations and assist the estimator step by
step to reach to a cost estimate in relatively short time.
In this study, an interactive cost estimation software named Forge Cost
Estimator, which performs the early cost estimation for forgings, has been
developed. The program is aimed to be used by the cost estimators in hot
forging companies. The software has various databases, which include material,
forging and machining equipment data. The cost items defined in the forging
work breakdown structure can be estimated by using different modules of the
software and summed up in an additive structure by using the bottom-up costestimation method. For calculating the forge volume quicker and easier, a new
volume estimation system named Easy-Volume, which is based on the
volume fragmentation method, is proposed. The software can also guide the
user in selecting the convenient forging production line. The software is written
in MS Visual Basic 6.0. The developed program has been tested in a forging
company and satisfactory cost estimations for several forgings have been
achieved.
