Apparatus for machining composite material test specimens

This application is drawn toward a combined coring and sawing machine for composite materials. The preferred embodiment combines the functionality of two machines typically used in the prior art and minimizes both the cost and errors associated with larger cutting tools, e.g. diamond cutting devices, used in the prior art. Combining variable speed motor operation with pressure actuated advancement of cutting tools and automatic workholding actuation provides a system which is effectively open-loop "load" controlled as opposed to the open-loop "displacement" control systems most often used in the prior art. Simple and economical specimen ejection techniques are a further improvement over the prior art which often includes no ejection facility at all.
