Abstract <p>Static errors of solid carbide end mills—such as eccentricity and skewed axes—displace the actual trajectory of the cutting edges from the intended path. That may result in nonuniform wear of the cutter teeth. In the present work, the influence of errors in measuring the radial runout associated with the eccentricity and the deviation of the mill axis from the chuck axis is measured. This research also reveals that measurement precision impacts the macroscopic contour of the end mill’s initial surface. Such effects must be taken into account in tool design, especially when using low-accuracy tool clamping systems. Improved monitoring of the end mill’s radial runout at tool setup will improve the quality of the tool’s surface layer and increase the dimensional precision of the workpiece.</p>
