IF-EdgeMasterHOB
Edge measurement at tooth flank, tooth root and tooth tip
The IF-EdgeMasterHOB is one of Alicona’s optical 3D tool measurement systems and a market specific adaption of the optical cutting edge measurement
device IF-EdgeMaster. A large working distance of 33 mm allows effortless measurement of cutting edges even in areas that are hard to access. Users
measure hob cutters at every stage of manufacture, regardless of surface finish or coating.
t
Users measure:
»t Edge roundness at tooth flank, tooth root and tooth tipt
»t Positive and negative bevel
»t Radius, wedge angle, true edge geometry (”waterfall“ t
»t Chipping and roughness
t and/or ”trumpet“ type) through ellipse fitting methodt
»t Wear and difference to CAD models or reference geometries

Accuracy
Wedge angle
β = 70-110 º
U = 0.15 º, σ = 0.02 º
Edge radius
R = 5 µm - 20 µm
R > 20 µm
U = 1.5 µm, σ = 0.15 µm
U = 2 µm, σ = 0.3 µm
“Being able to measure the edge radius of both, tooth tip
and tooth flank over this broad range is, as far as I know,
not possible with any other system.“
