Özet
The group of ferrous materials with more than 2% carbon in their chemical composition is commonly referredto as cast iron materials. Carbon Equivalent (CE) is an empirical value in weight percent, relating the combinedeffects of different alloying elements used in the making of cast iron to an equivalent amount of carbon.Statistical process control (SPC) can be applied in plants to obtain good quality and high standard productswhich have become very popular in many industries. Fuzzy process capability analysis by using X-R controlcharts gives more realistic results, developed with fuzzy theory. Fuzzy control charts are more sensitive thanSPC. This study contains construction of a system design to observe whether the conditions of an alloyproduction line are within the specification and control limits. To determine the average percentage of CEvalues, the fuzzy X-bar and R charts were applied to GG25 gray cast iron samples for 20 days’ production. Inorder to control the process parameters and improve quality of the cast products, the comparison of the statisticaland experimental results show that the fuzzy SPC methods can be simply applied on a foundry.
