چکیده

in manufacturing industry, it has been acknowledged that tool wear prediction has an important role in higher quality of products and acceptable efficiency. being an emerging area of research in recent years, drilling tool wear is an important factor which directly affects quality parameters of machined hole such as hole centring, roundness, burr formation and finished surface. in this paper, the genetic equation for prediction of drilling tool flank wear was developed using the experimentally measured wear values and genetic programming for two different materials, aisi1020 and aisi8620 steels. these equations could be used to compare the behaviour of wear in both mentioned materials and analyse the effect of materials characteristics on wear rate and wear pattern. the suggested equations have been shown to correspond well with experimental data obtained for flank wear when machining in various cutting conditions. the results of experiments and equations showed that properties of work material can affect drill bit flank wear drastically. it was concluded that greater toughness and strength of aisi8620, compared to aisi1020, lead to higher cutting stresses and temperatures, resulting more flank wear.

In-process prediction of corner wear in drilling operations

The paper presents an in-process prediction of corner wear in drilling operations by means of a polynomial network. The polynomial network is composed of a number of functional nodes and well organized to form an optimal network architecture using an algorithm for synthesis of polynomial networks (ASPNs). Thrust force or torque in drilling operations has been correlated with corner wear in this...
