A milling operation is performed on an NC machining center. Total travel distance L= 300 mm in a direction parallel to one of the axes of the worktable. Cutting speed = 1.25 m/s and chip load = 0.05 mm. The end milling cutter has four teeth and its diameter = 20 mm. The axis uses a DC servomotor whose output shaft is coupled to a leadscrew with pitch = 6 mm/rev. The feedback sensing device connected to the leadscrew is an optical encoder that emits 250 pulse/rev. Determine (a) feed rate and time to complete the cut along the travel distance L, and (b) rotational speed of the motor and the pulse rate of the encoder at the feed rate indicated.

Q/2 The motion of a pointer over a scale is resisted by a viscous damping torque of magnitude 4 N-m at an angular velocity of 2 rad / s. The pointer, of negligible inertia, is mounted on the end of a relatively flexible shaft of stiffness 2 N-m / rad, and this shaft is driven through a 1 to 4 reduction gear box. Determine the overall transfer function of the system? Gear box Pointer If the input shaft to the gear box is suddenly rotated through 1 completed revolution, determine the time taken by the pointer to reach a position within 1 percent of its final value ?
Consider two robot-manipulators:• A SCARA robot with joints displacement range q1,2 = −90◦...90◦ and q3 = 0..10cm and links lengths L1,2=10 cm.• A Cartesian robot with joint displacements’ range q1,2,3 = 0..10 cm.Which statement is correct?1) The Cartesian robot has a larger workspace.2) It is not possible to judge the workspace based on the information provided.3) Both robots have revolute joints.4) The SCARA robot has a larger workspace.
A manipulator’s end-effector position is calculated as follows:x = q0 cos q1 + l2 cos(q1 + q2),y = q0 sin q1 + l2 sin(q1 + q2),where q0,1,2 represent joint displacements and l2 is a constant positive parameter.Which of the following describes this manipulator:1) This is a robot-manipulator with 3 revolute joints.2) This is a robot-manipulator with 2 revolute and 1 prismatic joints.3) This is a robot-manipulator with 1 prismatic and 3 revolute joints.4) This is a robot-manipulator with 2 revolute joints. A robot’s end-effector’s tool position is defined asx = L1 cos(q1) + q3 sin(q1 + q2)where L1 = const, q1 = q1(t), q2 = q2(t) and q3 = q3(t) with t defining time. Calculate ∂x / ∂q3 1) it is impossible to calculate as the equation for the y and z positions are missing.2) cos(q1 + q2).3) it is impossible to calculate as time is not given.4) sin(q1 + q2).
The location of the tool, VT, is not accurately known. Using force control, the robot feels around with the tool tip until it inserts it into the socket (or Goal) at location ST. Once in this "calibration" configuration (in which {G}and {T) are coincident), the position of the robot, T, is derived by reading the joint angle sensors and computing the kinematics. Assuming T and Tare known, give the transform equation to compute the unknown tool frame, WT. {B} {S} {W} 2G {G} ÎT {T} ☆G XT 2T

A stepper motor serves as the drive unit for the linear joint of an industrial robot. The joint must have an accuracy of 0.25 mm. The motor is attached to a leadscrew through a 2:1 gear reduction (2 turns of the motor for 1 turn of the leadscrew). The pitch of the leadscrew is 5.0 mm. The mechanical errors in the system (due to backlash of the leadscrew and the gear reducer) can be represented by a normal distribution with standard deviation = ±0.05 mm. Specify the number of step angles that the motor must have in order to meet the accuracy requirement.
