- A NC machine tool table is powered by a servomotor, lead screw, and optical encoder. The lead screw has a pitch = 5.0 mm and is connected to the motor shaft with a gear ratio of 16:1 (16 turns of the motor for each turn of the lead screw). The optical encoder is connected directly to the lead screw and generates 200 pulses/rev of the lead screw. The table must move a distance = 100 mm at a feed rate = 500 mm/min. Determine (a) the pulse count received by the control system to verify that the table has moved exactly 100 mm; and (b) the pulse rate and (c) motor speed that correspond to the feed rate of 500 mm/min. Solve the problem assuming the optical encoder is directly coupled to the motor shaft rather than to the lead screw.A CNC machine tool table is powered by a servomotor, ball screw, and optical encoder. The ball screw has a pitch = 7.5 mm and is connected to the motor shaft with a gear ratio of 12:1. The optical encoder is connected to the ball screw and generates 200 pulses/rev of the screw. The table must move a distance of 300 mm at a feed rate = 450 mm/min. (a) Determine the pulse count received by the control system to verify that the table has moved exactly 300 mm. Also, what are (b) the pulse rate and (c) motor speed that corresponds to the specified feed rate?The worktable of a CNC machine tool is driven by a closed-loop positioning system that consists of a servomotor, ball screw, and optical encoder. The screw has 4 threads/in and is coupled directly to the motor shaft (gear ratio = 1:1). The optical encoder generates 180 pulses per motor revolution. The table is programmed to move a distance = 6.0 in at a feed rate = 25.0 in/min. (a) How many pulses are received by the control system to verify that the table has moved the programmed distance? Determine (b) the pulse rate and (c) motor speed that correspond to the specified feed rate.
- Chip 1 has 3 Ring Oscilltors on it. Calculate the Calibrated Ring Oscillator value for Chip 1 and Ring Oscillator. Use Oscillator 3 (RO3) on Chip 1 as a reference point (3.3 ghz). Use the formula attached to calculate the Calibrated RO_x on Chip_y . The RO values on Chips 1,2 and 3 are supplied as well. Any help on figuring out how to do this would be appreciated.Consider the level loop shown in Fig. 5-3.2. The steady-state operating conditions are f i = f o = 150 gpm and h = 6 ft. For this steady-state the FC valve requires a 50 % signal. The level transmitter has a range of 0 to 20 ft. A proportional only controller, with Kc = 1, is used in this process. Calculate the offset if the inlet flow increases to 170 gpm and the valve requires a signal of 57 % to deliver this flow. Report the offset in % of scale and in feet.Solve for the Vrms (magnitude only) across the capacitive reactance if R2 = 1082 ohms and Xc = 2328 ohms.

- The image below depicts one section of a cam shaft which opens a valve to release the pressure in the combustion chamber. In order to synchronize the position of the piston and the release of the valve, there is a sensor that measures the position of the camshaft. The sensor can determine when point a is 0.672 in. to the right of the center of the camshaft and 0.672 in. above the center of the camshaft. In a four stroke engine the crank shaft, which is connected to the pistons, turns twice for every turn of the camshaft. At cruising speed the crank shaft turns at 3,000 rotations per minute (rpm) which means that the camshaft turns at 1,500 rpm or 25 revolutions per second (rps). After 0.825 seconds, where would point a be in relation to the center of the camshaft?* Answer options are: (-0.589,0),(0.116, -0.316), (0,-0.95),(0.86,-0.315),(0.431,0), none of these are correct. Please be sure to show your steps.Explain the procedure adopted to arrive at the specification of piezo electric sensor charge amplifiercrank angle encoder and AD convener with data storage for heat release analysis of a given IC engine.A.
