8. Cutting faults
1. Miscut: Check for miscut or the failure of the Cutter to split the line. Tolerance is 1/16”.
2. Matching Plies: Check the top ply with the bottom ply to see that they are the same. Compare both to a hard pattern. Tolerance is 1/8”.
3. Ragged Cutting: Check for ragged cutting according to the standards of the customer. It is a judgment defect. It is important on critical parts and if it has to be re-cut then it is a defect.
4. Notches: 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”.
5. 10% of bundles in a cuts should be inspected

9. Tools for quality improvement Leather quantity check
Economy of leather cutting
Quality audit
Quality pointing for skill improvement

10. QUALITIES OF A CUTTER
Good Knowledge on the parts of the hide/skin & their suitability for cutting of components of the products.
Skill on recognizing Types of leather & their suitability for making different types of leather goods.
Identification of common defects & stretch of leather.
Assortment of leather for various thicknesses & their suitability for various components of the product

11. RECOMMENDATIONS FOR QUALITY CUTTING A. Before start cutting make sure:
That knife or dies are sharp.
The cutting block is well equalized.
The pattern given corresponds to the model to be cut.
The leather given corresponds to the sample.
The cutting patterns are interlocking among themselves or with the cutting patterns of the same model.
B. Eventually mark the defects of the skin with white chalk or pencil.

12. D. Cut the pieces according to quality properties:
C. Then sort the leather in order to cut the big sizes in the larger skins and the small sizes in the smaller skins. The results will be –
Better consumption
Thicker substance for the big sizes ad thinner substance for the smaller sizes which is much preferable.
D. Cut the pieces according to quality properties:
Quality – 1: In the best part of the skin.
Quality – 2: Shanks, Bellies and Neck.
Quality – 3: Waste
E. Check the footage of every skin before start to cut it and divide it by the average consumption of the model to be cut.
F. When work is finished it check with the aid of the control checklist.

13. CONCLUSION
To increase the productivity of any leather products industry, the cutting department is most important department. Because to prepare any type of product, quality starts from cutting department, every cutter has knowledge about quality of materials and cutting direction to make quality products. The productivity of cutting department depends on cutter. For this reason a special bonus can pay to every cutter.
