CUTTING OPERATIONS QUALITY

1
CUTTING OPERATIONS QUALITY

• OBJECTIVE MEASUREMENT OF CUTTING QUALITY

2
INTRODUCTION

• CUTTING QUALITY IS IMPORTANT TO THE SUCCESS OF A
  PRODUCT.
• QUALITY IN THE CUTTING ROOM HAS FABRIC AND
  OPERATIONS IMPLICATIONS.
• THE EFFECTS OF CUTTING QUALITY MAGNIFY THROUGHOUT
  THE MANUFACTURING PROCESS

3
NUMERICALLY GRADING SPREADING

• USE A PASS/FAIL SYSTEM OF GRADING
• DEFINE DIFFERENT KEY ELEMENTS OF RESPONSIBILITY
  FOR SPREADING
• DEFINE THE POINT AT WHICH EACH ELEMENT IS NOT
  ACCEPTABLE
• ASSIGN POINT VALUES TO EACH KEY ELEMENT

4
KEY ELEMENT, EDGING

• WHAT IS EDGING?
• WHAT IS ACCEPTABLE?
• IS IT DIFFERENT FOR DIFFERENT METHODS?...
  FABRICS?MACHINES?
• USE 1/2 FOR MANUAL SPREADING
• IF EDGING VARIATION IS 1/2 OR LESS, IT PASSES
  IF NOT IT FAILS.

5
EDGING EXAMPLES
6
KEY ELEMENT, CLAMP ENDS OR OVERSPREAD

• CLAMP ENDSTHE FABRIC SPREAD BEYOND THE ENDS OF
  THE MARKER
• ANY MATERIAL IS ABSOLUTE WASTE
• FOR MANUAL SPREADING USE A TOTAL OF 2 OVERSPREAD.

7
EXAMPLEOVERSPREAD
8
KEY ELEMENT, SPLICES

• SPLICES ARE PLACES IN A SPREAD WHERE THE END OF
  ONE PIECE OF FABRIC OVERLAPS A SECOND PIECE OF
  FABRIC TO INSURE NO PATTERN PIECES IN THE SPREAD
  ARE LOST.
• USUALLY MARKED WITH PAPER.
• USUALLY AT SPECIFIC POINTS IN THE SPREAD.

9
SPLICESCONTINUED

• MUST COMPLETELY COVER THE ENTIRE RANGE.
• A SPLICE IS ACCEPTABLE IF IT
• COVERS SPLICE AREA COMPLETELY.
• HAS PAPER MARKING ITS LOCATION.
• DOES NOT EXTEND BEYOND RANGE BY MORE THAN 2.

10
EXAMPLE...SPLICES
11
OTHER KEY ELEMENTS

• PLY HEIGHT
• ENDS MEASURED, FOLDED, ETC.
• CORRECT CLOTH DIRECTION
• CORRECT MARKER

• SPLITTER PAPER
• PAPERWORK CORRECT
• CORRECT METHOD OF SPREADING
• CORRECT ROLE SEQUENCE
• OTHER?

12
EXAMPLEENDS FOLDED
13
ASSIGNING POINT VALUES

• WEIGHTED OR UN-WEIGHTED?
• UNWEIGHTED100 DIVIDED BY TOTAL NUMBER OF KEY
  ELEMENTS POINTS PER KEY ELEMENT.
• WEIGHTEDASSIGN DIFFERENT NUMBER OF POINTS BASED
  UPON COMPANY SPECIFIC ISSUES.

14
UNWEIGHTED GRADING

• IF THERE ARE 8 KEY ELEMENTS
• AN ELEMENT IS WORTH 12.5 POINTS
• 100 / 8 12.5
• NUMERICAL SPREAD GRADE IS TOTAL PASS ELEMENTS X
  THE POINT VALUE.
• IF 7 ELEMENTS PASS, THEN THE GRADE IS 87.5 ( 7
  X 12.5 87.5).

15
WEIGHTED GRADINGAN EXAMPLE

• TOTAL OF EIGHT ELEMENTS.
• THREE ARE VERY CRITICAL TO CO.
• ASSIGN 15 POINTS
• FIVE ARE IMPORTANT.
• ASSIGN 11 POINTS.

• THE SPREADING GRADE IS THE TOTAL OF POINTS FOR
  ALL KEY ELEMENTS THAT PASS.
• 3 PASS _at_ 15 pts.
• 4 PASS _at_ 11 pts.
• GRADE IS 89

NUMERICALLY GRADING MARKER APPLICATION

• GRADING SYSTEM IS SAME AS SPREADING.
• KEY ELEMENT EXAMPLES ARE
• CORRECT MARKER(S)
• ATTACHED SECURELY AND CORRECTLY
• WILL MARKER FIT?
• TORN OR PLEATED MARKER?
