Question

In a multispindle CNC machine tool 3 operations are performed with times 50 70 and 80 seconds at each of its work centers The cycle time time required to manufacture one workpiece in seconds will be

• A. 200
• B. 66.66
• C. 70
• D. 80

Hint:

For multispindle machines the cycle time is determined by the slowest operation as all spindles work simultaneously

Answer 1

The Correct Option is C

In a multispindle CNC machine the cycle time is determined by the operation that takes the longest time since all operations are performed simultaneously In this case the operation with the longest time is 80 seconds
