Tool Force in Milling

Analysis of tool force indicates that feed force (force in the direction of feed) is only 20% of total tooling force. [1]. This bodes well for belt-driven universal axes, in that a 100 lb tool feed force limit allows for 500lb overall tooling force limit.

Published Cutting Forces

1. Analysis of published cutting forces shows only 100 Newton scale forces. [2] We have 5x this force allowance with the Universal Axis.
2. Here we have 50-100kg tool forces [3]
