Question

A modal analysis(hammer test) applied to a machining process be performed on a part(work piece) or on a tool. (T/F)

Milling process can create unpredictable locations of cut surfaces generated during chatter. (T/F)

An unbalanced rotating shaft is an example of a forced vibration. (T/F)

As a work piece changes shape during the manufacturing processes (material removed), the frequency of the work piece changes. (T/F)

It is possible to find a physical object that can be held in your hand that does not have a natural frequency. (T/F)

The lower the rotational speed, the greater the potential for eliminating chatter by understanding the stability lobe diagram. (T/F)

(T)Model analysis applied to a machining process be performed on a part or on the tool.

(T) Only in stable machining tool wear is predictable.

(T)An unbalanced rotating shaft is an example of a forced vibration. Single degree of fredom.

(T)Yes frequency will vary .

(F)Natural frequency depends on geometrical shape.

(F) chip width vs spindle speed graph is stability lobe diagram
