  In this research, application of statistical quality control process in Kishwood industrial company has been investigated. Statistical quality control process includes control charts and acceptance samplings. In this study, qualitative and quantitave characteristics of raw material and work in progress was investigated using standard tables and control charts ( U) were designed  for grooving, drilling, laminating and edge banding processes. In the raw material and work in progress, medium density fiberboard (16mm) lots, HPL veneer, purchased ABS stripe and the distance of the double hole from the edge of the piece in terms of quantative characteristic were investigated by MIL-STD-414 tables. In addition, purchased veneered particle board lot and the accuracy of the stripe in cabinet bottom parts in terms of qualitative characteristic were investigated by MIL-STD-105E tables. All the results were compatible with the acceptable standards of the company. Since lots data were located in the control limits, we can conclude that the whole process had been under control during the research time and can be used to control the future of the process. By calculating the process capability index (CP), it was found that grooving and drilling process have a very high capability, so the percentage of waste in these two processes is very low.
