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?

A stepping motor with 240 step angles is coupled to a leadscrew through a gear reduction of 5:1 (5 rotations of the motor for each rotation of the leadscrew). The leadscrew has 6 threads/in. The worktable driven by the leadscrew must move a distance = 10.00 in at a feed rate of 30.0 in/min. Determine: Number of pulses required to move the table, and The required motor speed and pulse rate to achieve the desired table speed.

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.

A motor drives a load for which the torque required is given by Tload=80020+ωm Nm The torque–speed characteristic of the motor is shown in Figure P15.12. a. Will this system start from zero speed? Why or why not? b. Suppose that the system is brought up to speed by an auxiliary driver, which is then disengaged. In principle, at what two constant speeds can the system rotate? c. If the system is operating at the lower of the two speeds and power to the motor is briefly interrupted so the system slows by a few radians per second, what will happen after power is restored? Why? d. Repeat (c) if the system is initially operating at the higher speed.
A tachometer has a transfer function of 2.5 V/1000 rpm. The tachometer is physically attached to a motor which is also attached to a 10:1 built in gear box; the tach produces 2V.
