PPT ON CUTTING DEPARTMENT.pptx

  1. Quality issues in Cutting department
  2. Cutting is separating of the garments in to its components and in a general form. It is production process of separating a spread into garment parts that are the precise size and shape of the pattern pieces on a marker. 2
  3. Cutting requires 3 skilled employees because failure to properly cut the fabric correctly could result in quality problems with fit and assembly.
  4. o Follow up fabric receiving by cutting section. o Check rolls ticket information/ report. o Check lab test report. o If shade/ shading are OK, then allow to layer. o Prepare layer report. o Maintain log book. 4
  5. ● Preparatory processes. ● Marker Making. ● Fabric Spreading. ● Cutting. ● Sorting and Bundling. ● Cut Panel Checking. ● Inputting. ●After receiving the fabric from the dyeing and finishing section, there are some processes to prepare the fabric for bulk production. All these processes combined can be called preparatory processes. 5
  6. 9  Finished fabric from dyeing & finishing  Fabric Inspection  Relaxation  Test of GSM, Diameter, shed, shrinkage, twisting, fastness etc.  Test cutting  Approval  Marker making  Fabric spreading  Cutting  Sorting (Sticker, Numbering)  Bundling  Cut panel checking  Input section  Send to sewing section
  7. Precision of fabric cutting: 7 Fabric cutting should be done accurately as per exact dimension of the pattern pieces in the marker. Cutting accuracy depends on sharpness of knife, skill of operator, and attentiveness of operator. Computer controlled cutting and die cutting have their self-cutting accuracy.
  8. Consistent cutting: 8 Whatever be the cutting method used for fabric lay cutting, it should be ensured that the shape of the cut components from top to bottom lay are of exact size and shape, otherwise the garments produced will be defective.
  9. Infused edge: 9 During fabric cutting, the friction between the fabric and blade; the blade produces temperature in the temperature may be up to 3000C. To avoid the problem: Reduce the height of the lay; o Reduce the cutting speed; o Use anti-fusion paper in the lay at regular interval; o Lubricate the knife during cutting.
  10. Supporting of the lay: 10 Surface of the cutting table depends on methods of fabric cutting. The table surface should be capable to support the lay as well as to ensure that all the plies are cut at a time during fabric cutting.

  13. Round knife: 13 ●large production. ●Lubrication is manually done. Very low r.p.m. & knife height. ●Manual grinder is used. ●Low since few number of lay can be cut. ●Difficult to cut small components & high curve line. ●Not suitable productivity for
  14. Band knife: 14 ●Not suitable for large component due to the length of the table. ●Work load is high as machine is stationary & fabric is movable. ●Running cost is higher. ●Required fix space. ●Not possible to cut fabric directly.
  15. ⚫ Straight knife: ⚫ High speed of the machine causes high risk of damage. ⚫ Faulty knife could damage fabric layer. ⚫ Motor weight creates knife deflection which may be creates faulty pieces. ⚫ Risk is high for physical damage of operator. ⚫ Knife required to replace. 15
  16. Notches: 16 ●Only use to make notch to the fabric. ●Thermoplastic fiber can’t cut by this machine. ●The use of machine is limited.
  17. Die cutting:  Die die cutting involves pressing of rigid blade through the laid fabric. The die is a knife the shape of the pattern periphery, including notches  cutting: 17

  19.  Fill out top half of sheet  Open container. Make sure that all the parts listed on the skid are in the skid  Check tickets for correct cut #, style #, color #, size, and unit count.  Check c- boxes for proper labeling and correct amount of parts.  Complete audit form. Check each bundle for tickets, correct unit count, and fabric 19
  20. Miscut: 20 Check for miscut or the failure of the Cutter to split the line. Tolerance is 1/16”. Report all defects for miscuts to Cutting Foreman (Supervisor).
  21. Matching Plies: 21 Check the top ply with the bottom ply to see that they are the same. Compare both to a hard pattern or paper maker. Tolerance is 1/8”.
  22. Ragged Cutting: Check for ragged cutting according to the standards of the customer. It is a judgment defect. It is important on critical parts that if it has to be re-cut then it is a defect 22
  23. Notches: 23 Check the notch location by placing the pattern over the top ply. Any critical notch missing needs to be checked 100%. Tolerance is 1/8
