Lower Control Limit (LCL;) = inches (round your response to three decimal places). Based on the x-chart, cutting process has been The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCLR) - inches (round your response to three decimal places). Lower Control Limit (LCLR) - inches (round your response to three decimal places). Based on the R-chart, the wire cutting process has been
