Effect of tool setting error on the topography of surfaces machined by peripheral milling

Model for the prediction of heterogeneity bands in the topography of surfaces machined by peripheral milling considering tool runout

“…In this paper, tool setting error is considered as the sum of two errors: the parallel axis offset and the tilt angle between the tool axis and the spindle axis [4,5]. This error is characterized by five parameters: the parallel axis offset r, the tilt angle t, the tool overhang length L and the locating angles l and f. These parameters are defined in detail in [10].…”

“…where T is a transformation matrix depending on tool setting error parameters (r, t, L, f and l) and derived in [10].…”

“…(10) and (11) and approximating R(i,k) to the value at height z T OTi instead of its value at z T Pði;kÞ , the effective radius r(i,k) of tooth k at height z i can be approximated to:…”

“…The generation of heterogeneity bands due to errors in the tool setting has been reported in literature [2,7,8]. The effects of tool setting error on the heterogeneity bands generated on the milled surfaces have been evaluated quantitatively in [10]. But these models only consider tool setting error but not cutter grinding errors (CGE) errors arising from the sharpening of tool cutting edges.…”

Influence of eccentricity on roughness distributions in side milling

“…These authors all observed that eccentricity leads to higher surface roughness, which results from one of the cutting edges removing more material than the other ones, in a scenario resembling milling with only one tooth per revolution. Considering tool setting error, which contains both parallel axis offset and tilt, (Arizmendi et al, 2009) observed that width of heterogeneity increases with tool setting error, while (Buj-Corral et al, 2011) found that width decreases with helix angle of the milling tool.…”
