Machine Capability Index (Cmk) Definition
Definition of Machine Capability Index (Cmk): This is a shortterm machine capability index derived from the observations from uninterrupted production run Even though the formulae are as same as Cp and Cpk calculations, the standard deviation used here is sample standard deviation (RMS) The preferred Cmk value is >167 Definition of Cmk: Machine capability index – should be 200 or higher See also Cpk Calculated using continuous/uninterupted samples Also known as shortterm capability Cmk > 167 is the preferable situation Usually, longterm capability studies are done in a machine Process after achieving the required Cmk valueCmk Definition iSixSigmaMachine capability index is an index derived from the observations from uninterrupted/continuous production run It is often known as Cmk It is a shortterm capability index and also called initial process capability The longterm capability index can be calculated for a Machine Capability Index What is Six Sigma Machine capability Machine capability is measured in Cm and Cmk; it is a snapshot picture that shows how well a machine is performing right now in relation to the tolerance limits Figure 6 shows some examples When measuring machine capability Cp, Cpk, Cm, Cmk, control limits Machine capability index is an index derived from the observations from uninterrupted/continuous production run It is often known as Cmk It is a shortterm capability index and also called initial process capability The longterm capability index can be calculated for a machine/process after achieving the required Cmk value汽车行业工具 I Cmk机器能力指数定义与应用 知乎
Cmk and Cpk When will we need to calculate Cmk?
I believe Cmk pertains to machine capability and the data does come from a production characteristic for which specs or tolerance limits would be defined you need to ensure that the variation in the process is due to machine alone Cmk is calculated just as Ppk CmK is a measure of machine capability This is also called initial process capability This is measured using50 or more continuous samples produced on a machine, keeping all influences other than the machine parameters constant (like RM, Measuring, Operators, etc) Formula for calculating CmK What are the differences between Cpk and Cmk and 问题描述：最近刚刚开始接触汽车行业＆16949体系，有一个公司要求PPAP提交设备能力指数，测算Cmk值。我觉得应该世五大工具里SPC里的内容，可是没有结果。希望各位高手赐教！谢谢！请 请问Cmk值（设备能力指数）怎么测算啊？百度知道 Baidu Definition of Cmk: Machine capability index – should be 200 or higher See also Cpk Calculated using continuous/uninterupted samples Also known as shortterm capability Cmk > 167 is the preferable situation Usually, longterm capability studies are done in a machine Process after achieving the required Cmk valueCmk Definition iSixSigma CmK is a measure of machine capability This is also called initial process capability This is measured using50 or more continuous samples produced on a machine, keeping all influences other than the machine parameters constant (like RM, Measuring, Operators, etc) Formula for calculating CmK What are the differences between Cpk and Cmk and
