The following paper presents a method for the determination of the burr dimensions to be expected in shorthole drilling, simultaneously taking the parameters into consideration which influence the burr formation. These parameters are yield stress, forces and the geometry of the inserts. The method is based on empirical cutting examinations and takes account into the correlation between different burr parameters and the machining conditions such as cutting speed, feed and tool geometry. Using Schaefer's burr value g, it is possible to make a quantitative evaluation of the burr dimensions. The method was verified for the materials 16 MnCr 5 and Ck 45 in case of dry machining.

Experimental modeling of burr formation processes has received limited industrial application. This limited use is due to the large number of parameters in the experimental design resulting in a large number of experiments and high costs. This paper presents a methodology to combine experimental, si
