Burr formation in short hole drilling with minimum quantity lubrication

Abstract

Machining with minimum quantity lubrication (MQL) is state of the art. Previous investigations were, however, concerned with tool optimisation and the surface quality of workpieces as well as coating technology. By now the same or partly better machining results than in conventional cutting with flood lubrication can be achieved due to adjusted tool geometries, workpiece materials and coatings. Tests about burr formation in short hole drilling exist for dry cutting or the machining with emulsion. This paper expands these results to the burr formation in machining with MQL.

Burrs—Analysis, control and removal

“…Min [107] examines the interaction between the cutting edge of the drill and the exit surface in terms of cutting parameters, drill geometries and workpiece geometries. Heisel investigates the influence of MQL on burr formation in short hole drilling [61].…”

Minimum Quantity Lubrication (MQL) in Machining: Benefits and Drawbacks

“…Ref. [44] investigated the influence of burr formation using MQL in up-milling, down-milling and face milling. The main findings indicate that variation in cutting speed showed no influence on burr formation.…”

A technology enabler for green machining: minimum quantity lubrication (MQL)

“…Recently, in June 2009, a study (Heisel et al , 2009) was conducted to investigate the influence of burr formation using MQL in up‐, down‐ and face‐milling. The main findings indicate that variation in cutting speed showed no influence on burr formation.…”
