Machine Capability Study

Process reliability in the Screwdriving Technology

An extensive inspection within the limits of a Machine Capability Study, takes place by means of regularly tested reference-transducers.

For electric tools, we can also offer a machine capability study for their angular-displacement.

A Machine Capability Study is the testing of a machine in regards to its suitability for a special production- or tightening task.

Contrary to the Machine Capability Study, a Process Capability Study (Cpk) can only be performed directly on the assembly line and under inclusion of all influencing factors of the screwdriving process.

By stating a Cmk-value, a clear statement in regards to the machine capability is possible.

A Cmk-value of 1.67 means, that 99.99994 percent of the assemblies are within the allowable tolerances.
