One-sided Process Capability Assessment in the Presence of Gauge Measurement Errors

ثبت نشده
چکیده

Montgomery [31] recommended some minimum quality requirements on . For existing processes, the capability must be no less than 1.25, and for new processes, the capability must be no less than 1.45. For existing processes on safety, strength, or critical parameters, the capability must be no less than 1.45, and for new processes on safety, strength, or critical parameters, the capability must be no less than 1.60. Using the index , the practitioners can evaluate their process capability and make decisions. I C

The Effect of Gauge Measurement Capability and Dependency Measure of Process Variables on the MCp

It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. These indices have been widely used in the manufacturing industry for measuring process reproduction capability according to manufacturing specifications. In the past few years, univariate capability indices have been introduced and used to characte...

One-sided Process Capability Assessment in the Presence of Measurement Errors

In the manufacturing industry, many product characteristics are of one-sided specifications. The well-known process capability indices CPU and CPL are often used to measure process performance. Most capability research works have assumed no measurement errors. Unfortunately, such an assumption is not realistic even if the measurement is conducted using highly sophisticated advanced measuring in...

Testing capability indices for one-sided processes with measurement errors

In the manufacturing industry, many product characteristics are of one-sided tolerances. The process capability indices C p (u, v) and C l p(u, v) can be used to measure process performance. Most research work related to capability indices assumes no gauge measurement errors. This assumption insufficiently reflects real situations even when advanced measuring instruments are used. In this paper...

Gauge Imprecision and Process Capability Analysis

Alternative definitions of Process Capability Indices (PCIs), based on different approaches, have been proposed in literature. Most of the research works related to Process Capability Indices assume no gauge measurement errors. However, in industrial applications, despite the use of highly advanced measuring instruments, account needs to be taken of gauge imprecision. The aim of this paper is f...
