There are 20 automatic turning machines in the lathe department. batches of parts are machined in the department, each batch consists of setup and run times. batch size = 100 parts. the standard time to set up a machine for each batch is 5.0 hours. four setup workers perform the setups. they each work 40 hours per week. once a machine is set up, it runs automatically, with no worker attention until the batch is completed. cycle time to machine each part = 9.00 min; thus, it takes 15 hours of run time to produce a batch. assume all machines are perfectly reliable. what is the production output of the lathe department in 40 hours of operation per week?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
