GSD analysis of a sewing process

 We know, the history of GSD or the meaning of GSD. Today we try to know its application in the garments industry. How can we use GSD to identify or the way to figure out a standard sewing process SMV. 

Before starting, I have to discuss the basic motion of sewing. We know that A sewing process has below listed basic motion. 

1. Pick up 

2. Align 

3. Put under the pressure foot 

4. Sewing 

5. Dispose

 

Without the above-listed motion, a sewing process can not be completed. GSD just break these basic motion into many many micro motions. To know the basic idea of GSD please visit our previous post by clicking this.

 First of all, We have to show the below-linked sewing process video. It is the front-rise join process of the leggings item. After watching, we will analyze it with GSD & calculate the SMV of this process. And it is the standard process time for this Sewing process. Let's see the video:-

Process name:- Join front-rise

Machine type:- 2N/4T/OL

In this video, The operator is using 8 motions. The GSD analysis of these motions are:-

CODE	Motion Details	TMU
AS2H	Get parts with 2 hands	42
MG2T	Match and get 2 parts together	76
FOOT	Put under the pressure foot	38
MS1A	Sew approximately 1 cm	17
AM2P	Align and match 2 parts	61
S10NA	10 cm straight sewing	34
TBLD	Tread cut with fixed blade	33
FUNF	Form layout or remove	23
Total TMU of this process	324

We got the total TMU(time measuring unit) of this process as 324

So, the SMV of this process will be = (324/33.33)=9.7 

And, It is the standard all over the world for this process.
