Cycle Time and Hole Quality in Drilling Canned Cycle

The aim of this work is to present a feed rate modeling in drilling cycle taking into account the kinematic behavior of machine tool and an experimental study is carried out to validate it. Based on this model, a cycle time for the chip-breaking cycle and the deep hole cycle has been calculated. In particular, a precise estimation of cutting time has been predicted. Then, the effects of the value of the programmed feed rate and the incremental distance size on the kinematic behavior of the tool has been investigated. Moreover, a comparative study between this two-cycle type has been shown in term of kinematic profile and quality of the drilled hole (diameter error and cylindricity).
