This project has been engaged in a manufacturing methods program which was directed at the problem of resolving the theory of self-excited chatter such that it would encompass milling operations, in addition to turning and drilling operations. Concurrent with this investigation, parallel tasks were conducted to investigate analytical techniques that could be used to predict the static and dynamic characteristics of machine tool structures at the drawing stage, to investigate observed phenomena of the cutting process associated with metal cutting dynamics, and to investigate techniques whereby chatter specifications could be formulated and used to measure the chatter-free performance of machine tools.

The report contains a program of research which is directed at the problem of determining the dynamic stability of machine tool-metal cutting systems. Such a study will provide machine tool manufacturers with the necessary analytical methods tests and specification techniques to determine a vibration free cutting for machine tools. The special advantage of the system analysis by means of stochastic signals is the natural kind of stressing during the record of signals for the dynamic compliance test. (Author).

A theory is formulated using a feedback loop to represent the chatter mechanism. This theory permits the calculation of borderlines of stability for a machine tool system having a structure with n-degrees of freedom. A cutting stiffness table is presented in which data from the literature are given in a form of cutting stiffness per unit width of cut for various materials. The dynamic behavior of the cutting process is explored in depth yielding an understanding and qualitative description of observed dynamic behavior. The theory of transfer functions of structures has been derived enabling the prediction of structure dynamics of simple continuous systems. Measured and computed stability diagrams are presented demonstrating the validity of the developed stability theory. From the research program initial chatter specifications have been formulated. Such a specification, if established, would define the ratio of minimum directional dynamic stiffness of the structure over the rated horsepower of the machine tool. (Author).

In continuation of the efforts towards a general statistical evaluation of the available test data on several machine tools, eleven case reports concerning gear hobbing machines have been studied. The special characteristics of the gear hobbing process seem to allow a fairly simple specification for this class of machines. The improvements on the test rig for rotatory excitation of gear drives have been discussed and the design features and calibration characteristics of a new torque and displacement transducer are reported. Further description of circuitry and performance characteristics of some parts of the electronic apparatus devised for instantaneous measurement of transfer functions in general and cutting stiffness in particular are presented.
