In a workshop, a repetitive stopwatch time study was conducted on the machining operation of a "Gear- Case Casting" shown in the below drawing
• This operation was divided into 7 elements (A, B, C, D, E, F, G).
• Only G element is not occurring regularly in every cycle, since it is to clear the table of the machine from metal ships. Therefore, element G is occurring every 2 cycles.
• The stopwatch readings(in seconds) are shown in the next table
• The manager of this workshop agrees to use 5% as Personal and fatigue allowances and 2% as Delay allowances.
• Find the standard time to produce one Gear- Case?
