Description

This dataset comprises the average values of the components of machining force (cutting force, feed force, and passive force) measured during radial grooving of AISI 1045 steel and the surface roughness (Ra and Rt) of the resulting machined surfaces. Two variations of radial grooving are represented in this dataset: single grooving, were the entire cutting edge of the tool is used, and partial grooving, were only a fraction of the cutting edge is used. Three lubri-cooling methods were evaluated in this study: flood (WET), compressed air (AIR), and minimum quantity lubrication (MQL). The analysis of the presented data indicates that both AIR and MQL may be suitable environmentally friendly substitutes for traditional WET lubrication in radial grooving.

Steps to reproduce

Doe In this study, a factorial design of experiments was used, with three machining parameters (cutting speed, feed rate, and lubri-cooling condition) tested at three levels for each grooving type (single and partial). Three replications were used. Part material 170 HV AISI 1045. Cutting tool 3.0 mm wide coated carbide inserts (Sandvik N123F2-0250-0002-CM 4125) with an LF123F20 2020B tool holder. Cutting parameters Fixed: Depth of cut (ap): 3.0 mm (single grooving); 2.5 mm (partial grooving) groove depth (ar): 10.0 mm Variable: Cutting speed (vc): 150, 175, 200 m/min Feed rate (f): 0.050, 0.075, 0.100 mm/rev Lubri-cooling condition: WET, AIR, MQL Parameters associated to the lubri-cooling conditions: WET: BD-Fluid B90 water-miscible bio-lubricant at 20 % wt. Flowrate: 12 l/min. AIR: compressed air provided at 600 kPa. Flowrate: 42 l/min. MQL: Quimatic Jet water-based synthetic fluid. Flowrate: 4 ml/min.
