Subject: calculation of costs in PVD industrial processes

Dear members

I would like to know if anyone knows a good software tool to calculate the real cost of an industrial coating using PVD or other vacuum deposition technlogies.
We have developed our own software. The costs found in several websites and some technical documents have many times big discrepancies.
For example the cost of a cathodic arc deposition (and unbalanced magnetron sputtering) of TiN about 3-4 micron thick in a small insert of Tungsten Carbide has been estimated as about $0.50 for a daily production of about 1000 pieces, but values from $0.05 to $1.00 were
found! probably due to not take in acount the cost of depostion
equipment and/or quantity of pieces to be coat.

Is there any relation (constant factor) between a cost by arc, sputtering, PA-CVD for a certain type of coating/thickness and quantity to coat? (for example Magnetron sputtering=1.5*Cost of Cathodic Arc for TiN ?!)


I would appreciate very much your comments and experiences.
