1. The following data resulted from a study taken on a horizontal milling machine:

Pieces produced per cycle: 8.

Average measured cycle time: 8.36 minutes.

Average measured effort time per cycle: 4.62 minutes

. Average rapid traverse time: 0.08 minutes.

Average cutting time power feed: 3.66 minutes.

Performance rating: 115 percent.

Allowance (machine time): 10 percent

. Allowance (manual time): 15 percent.

The operator works on the job a full eight-hour day and produces 380 pieces. How many standard hours does the operator earn? What is her efficiency for the eight-hour day?

2. An analyst has estimated that there will be an 84% learning curve for an assembly operation. The first assembly takes 48 minutes and the standard time is set at 6 minutes.

a. How long will it take the operator to reach the standard time?

b. Unfortunately, the operator falls ill after the first week on the new assembly operation and returns after one week. What will be the estimated time for the operator to reach standard time now?

Expert Solution

Answer: Standard hours operator earn =8.094 pieces per day

Answer: Efficiency==1.012 pieces per hour

The following data resulted from a study taken on a horizontal milling machine:

Pieces produced per cycle: 8.

Average measured cycle time: 8.36 minutes.

Average measured effort time per cycle: 4.62 minutes

Average rapid traverse time: 0.08 minutes.

Average cutting time power feed: 3.66 minutes.

Performance rating: 115 percent.

Allowance (machine time): 10 percent

Allowance (manual time): 15 percent.

The operator works on the job a full eight-hour day and produces 380 pieces.

How many standard hours does the operator earn?

*Allowance (machine time taken as 1.10) and 1 represents one day of operation.

Standard power feed cycle time= Average cutting time power feed+ Average rapid traverse time * 1 *1.10

=(3.66+0.08)*1*1.10=4.114 minutes

Allowance (manual time taken as 1.15)

Standard manual time cycle= Average measured cycle time- (Average cutting time power feed+ Average rapid traverse time )*1.15*1.15

=(8.36-(3.66+0.08))*1.15*1.15=6.110 minutes

Standard time= Standard power feed cycle time+ Standard manual time cycle

=10.224 minutes

Standard rate per piece=standard time/ 8

=10.224/8=1.278 minutes

Standard hours operator earn=standard rate per piece*(number of pieces produced per day/60)

=1.278* (380/60)

Answer =8.094 pieces per day

What is her efficiency for the eight-hour day?

Efficiency= Standard hours operator earn/8 hours a day

=8.094/8

Answer: Efficiency==1.012 pieces per hour
