includes the activities of marker planning, spreading and preparation for
sewing.

Requirements of fabric cutting:
In achieving this objective, certain requirements must be fulfilled:
1. Precision of cut
2. Clean edges
3. Unfused edges
4. Support of the lay
5. Consistent cutting
1. Precision of cut:
Garments can not be assembled satisfactorily and they may not
fit the body correctly if they have not been cut accurately to the pattern
shape.
Its
depends upon some factors;
The
method of cutting employed
· The
market planner
· Marker
making
· Skill
ness of the opeartpor
2. Clean edges:
The raw edge of the fabric should not show fraying or
snagging. To get this knif blade must be well sharpended.
3. Unfused edges:
The build-up of heat in the knife blade comes from the
friction of the blade passing through the fabric. This, in extreme, leads to
scorching of the fusing of the raw edges of thermoplastic fibre fabrics such as
polyamide and polyester.

Remedy:
· Use anti-friction paper between the
layers
· Showing down cutting speed
· Use well-sharpened blade
4. Support of the lay:
The cutting system must provide the means not only to support
the fabric, but also to allow the blade to penetrate the lowest ply of a spread
and sever all the fibers. Polyethyene
sheet is kept over table and gum tape is used to fix it.
5. Consistent cutting:
To get the consistency of cutting, all plies are clamped
tightly to the table so that all pieces are cut some pressure of plies occur.
