Frequently Asked Questions About Cutting Tool Measurement
What can be measured on a cutting tool?
Optical 3D metrology can be used to measure cutting edge geometry, surface roughness, tool geometry, defects, chipping and wear. Depending on the tool, relevant characteristics include edge radius, diameters, angles, margins and webs.
How are cutting edges measured optically?
Optical 3D metrology enables non-contact measurement of cutting edges and their actual form. In addition to conventional radius evaluation, asymmetrical edge geometries such as waterfall and trumpet shapes can be characterized using additional geometrical parameters.
What can be measured on drills and milling cutters?
Optical 3D metrology can measure both surface and dimensional characteristics of drills and milling cutters. Relevant parameters include cutting edge geometry, flute roughness, outer and core diameter, helix angle, drill tip angle, rake angle, margin and web.
Can optical metrology measure both surface roughness and tool geometry?
Yes. Optical 3D metrology enables the measurement of form and roughness within one measurement approach. It can evaluate profile- and area-based roughness as well as geometrical characteristics and complete 3D form.
Can round tool measurement be automated?
Yes. Round tool measurement workflows can combine digital measurement planning, tool alignment and automated measurement. With Automatic Round Tool Alignment, measurement positions can be defined based on digital tool data and the physical tool aligned with the measurement strategy before measurements are performed at the defined positions
