WebAnalyze not just parts and operators, but up to eight additional factors. Perform an analysis even with incomplete data (unbalanced studies). Include factors that are fixed or random for greater flexibility. Include More than Two Factors in a Gage R&R Study Traditionally, Gage R&R studies focus on just two factors: parts and operators. WebIf the Total Gage R&R contribution in the %Study Var column (% Tolerance, %Process) is: Less than 10% - the measurement system is acceptable. Between 10% and 30% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.
