Testbed device for use in predictive modelling of manufacturing processes

A testbed device, comprising:

• a base;
• a displaceable machine table supported on the base;
• a sample holder supported on the displaceable machine table;
• a displaceable spindle supported on the base;
• a video microscopy system, including a camera, a microscope and a light source;
• a plurality of sensors adapted to measure force, vibration and thermal emission;
• a tool holder carried on the displaceable spindle, the tool holder being adapted to hold a cutting or burnishing tool;
• and
• a control module including a controller, an X-actuator, a Y-actuator and a Z-actuator wherein the controller is adapted to (a) control the X-actuator, the Y-actuator and the Z-actuator, (b) receive data from the plurality of sensors, and (c) receive data images from the video microscopy system wherein the testbed device further includes a carbon fiber rod assembly integrated into the tool holder, a first laser interferometer targeting a first target element at a first end of the carbon fiber rod along a first line and a second laser interferometer targeting a second target element at a second end of the carbon fiber rod along a second line perpendicular to the first line.
