Title: Cutting piece for peeling, optionally turning
Inventor: LANG GERNOT
IPC: B23B27/14
Filed: 1994-05-13
Abstract: The invention relates to a cutting tip for peeling or shaft turning with at least one main and secondary cutting edge. The invention consists in the fact that at least the main cutting edge (1) is arranged inclined towards the cutting tip (5) by an angle ( alpha ). The advantages achieved by the invention consist in particular in the fact that, in the case of a main cutting edge (1) and a secondary cutting edge (2), a very large effective secondary cutting edge can be realised and thus very large feed rates can be set. It should be especially emphasised that, at a given length of the cutting tip and preset ratios between main and secondary cutting edges, a total of four cutting-edge systems for example, consisting of main and secondary cutting edge, can be arranged. As a result, large secondary cutting edges are available, so that work can be carried out at large feed rates with such cutting tips while obtaining a good surface quality of the workpiece to be machined. <IMAGE>

Abstract: A system for sensing the vibration and lateral force in a cutting tool for the purpose of keeping these two operating parameters within tolerable limits. A piezoelectric crystal is mounted in the chuck supporting the cutting tool. The mechanical stresses on the crystal produce an electrical signal which is then separated into vibration and lateral force components. The negative d.c. analog voltages of these components are summed with a positive d.c. voltage analogous to the programmed feed rate, the algebraic summation resulting in an adaptive control voltage which is used to modulate the spindle power in accordance with the ambient vibration and force.
