Plain Sewing Machine
Edge Finishing Machine
Flat Seam Construction
Decorative Stitching
Short Explanation :- Calculate the total sewing length of the garment body in inches. Then convert the result into meters by dividing by 39.37.
Note: Length, Width, and Height are usually measured in centimeters (cm).
Short Explanation :- Round the calculated result to the nearest even number. In this case, the nearest even number is 16, so the button size is 16L.
Cycle Time means the time required to complete one operation. During a time study, the same operation is observed 5–10 times using a stopwatch.
Here, only one process SMV is shown. Calculate the SMV of all other processes in the same way.The sum of all process SMVs gives the total SMV of the full garment.
100 ÷ 100 = 1.00
A rating of 100% represents normal working speed. The rating factor is 1.00.
85 ÷ 100 = 0.85
A worker performing below standard speed receives a rating factor of 0.85.
110 ÷ 100 = 1.10
A worker performing faster than standard speed receives a rating factor of 1.10.
Basic Time = 0.375 minute × 1.10
SMV = 0.4125 × 1.15
