Abstract
This papers deals with an experimental study of metal cutting, particularly gundrilling. It argues that a proper experimental methodology based on the design of experiments (DOE) is an appropriate instrument to improve productivity and efficiency of machining. A screening DOE based on the random balance method and the Plackett-Burman screening design is considered. Such a DOE is referred to as a sieve design. The proposed method has proven to be very useful at the first stage of an experimental study of complex parameters as, for example, tool life testing, where the experimentalist wishes to include into consideration many design and process parameters. Conducting a relatively simple sieve DOE, the experimentalist easily can distinguish significant factors and their interactions of any order to be used in the subsequent full block DOE. A practical example of an application using the proposed DOE, a tool life test of gundrills, is considered in detail.
