1. Lecture 17 Cutting Department

2. Marker making….  Efficiency of marker = (Area of patterns in marker plan / Total area of the marker plan) X 100

3. Cutting Losses…  End Loss  Width Loss  Splice Loss  Buffer Loss  Remanent Loss

4. Cutting Losses

5. Objectives…  Objective of cutting is to separate fabric parts as replicas of the pattern pieces in the marker plan.

6. Points to be considered…  Precision of cut –Accurate cutting according to the marker  Clean edges: –Raw edges of fabric should not be frayed  Un-fused edges: –Edges are fused due to the heat generated due to the friction of blade and fabric

7. Cutting method & Instruments… 1. Manual –Hand shears –Straight Knife –Round Knife –Band Knife –Notchers –Drills and Shear markers

8. Manual Cutters

9. Cutting method & Instruments… 2. Computer Controlled Cutting –Straight Knife –Die cutting –Laser cutting –Plasma cutting –Water jet cutting –Ultrasonic cutting

10. Automatic Cutters
