STABILITY ANALYSIS OF THE TECHNOLOGICAL PROCESS OF MECHANICAL WOOD PROCESSING USING CONTROL CHARTS

This paper presents a quality control tool, that is, method, which in this case concernsthe mechanical processing of wood, but general, it can be implemented any form production (mechanicalengineering, traffic, food technology...). The goal the research is to show way applying chartmethod, determine stability technological process wood order beable define appropriate corrective measures improve part process. controlchart was created graph consisting horizontal (abscissa) and vertical axis (ordinate). Theorder observations plotted on abscissa, corresponding values ordinate. Apart from theprecise creation charts, their correct interpretation also great importance. It easiest interpretcontrol charts where "outside statistical control", individualmeasurements are outside limits. means some special cause variation present processand an adjustment needs made. However, placing all points within limits, obtaining acontrol map "within does not necessarily mean such isacceptable by statisticians. On basis results, has shape brokenline, we observe whether limits have been exceeded, draw certain conclusions about stabilityof If between conclude our stable undercontrol, normal there jumps, ie. if value someobservation out bounds (above upper limit or below lower limit), then thatour stable, under In case,certain were proposed, should woodprocessing bring control.Control as engineering-mathematical very suitable tool for achieving goals statisticalcontrol. Optimal application ensures constant monitoring process, direction towards thedesired flow undertaking possible measures. Also, fulfillment thedesigned required characteristics, requirements standard. Withtheir simplicity reliability, they provide users with convenience work relevant processindicators, controllers valid data flow. As such, represent thatkeeps entire given
