:) Cutting forces should be kept constant during machining operations to prevent chang in spindle speeds or work position. Such changes would deteriorate the accuracy oft work's dimensions. A control system is proposed to control the cutting force. The pla is difficult to model, since the factors that affect cutting force are time varying and n easily predicted.

In the Electric Field Mapping experiment, you used two electrodes separated by a distance L and a power supply with emf Vo. You measure V for points along a straight line perpendicular to the electrodes and joining their centers by connecting the negative terminal of the voltmeter to the cathode and the positive terminal to the pointer placed at a point in the tray along the line a distance d from the cathode. Which of the following is true? O a. The positive terminal of the voltmeter should be connected to the cathode and the negative terminal to the point between the two electrodes. O b. You should vary d but keep Vo fixed. O c. The slope of V vs. d is positive and depends on Vo only. O d. There is a linear relation between d and L. e. The slope of the calibration curve is negative.

Q8 - You wish to end up with a 2um width metal line (measured at the top of the metal lead cross section). A) You are using an isotropic wet etch process on a 1um thick metal layer. What linewidth should the protective photoresist line be to get these results? Sketch the resulting structure before photoresist strip. B) now you are using a completely anisotropic etch, what is the requisite linewidth of the photoresist to achieve the same end goal? Sketch the resulting structure before the stripping of the photoresist.

From your understanding, what is the differnece between a grounding wire and a grounded wire? I answered this way ... Grounding wire is connecting to ground or to a conductive body extends the ground connections. Whereas the grounded wire is connected to earth or to some conducting body that serves inplace of the earth. The replied I got from a classmate "I feel your definitions here aren't exactly different. The first describes connecting to ground and the second to earth. Those are one and the same. Am I missing your meaning, or do I have that correct?" Is he right or am I really missing the subject? Please reply me soon. Thank you
