摘要

Following a lathe turning operation modification in order to work in dry machining condition, it appears that new tools and cutting condition modifications where insufficient to recover surface quality previously obtained with cutting fluid. Indeed, workpiece temperature evolutions produced with a single tool insert have conducted preventive replacements but no law where found for this substitution. Some responses have been found in literature review, especially on cutting zone temperature estimation in orthogonal and dry cutting with a new tool. But no solutions are provided to avoid production drop due to the important temperature raise in the cutting zone. The aim of this paper is to study tool flank wear influence on workpiece temperature distribution during dry cutting operations. The first part stands up a new analytical model, which takes account of tool wear and elastic deformation of the workpiece in heat generation in the cutting zone. The second part shows by an experimental procedure that temperature growth in cutting zone during machining process is dependant on the tool flank wear evolution.
