Cut Order Planning
A cut order plan is a logical
division of an order quantity into
lays (spread) of fabric such that
desired number of garment
pieces can be cut in the required
size ratio.
Cut order plan is made to
minimize time and effort in cutting
as well as to utilize fabric
efficiently.

Sewing Schedule
The sewing schedule is a detailed plan that outlines
the sequence and timing of sewing operations for
each garment style.
It considers factors like garment complexity,
machine availability, skill requirements, and
production targets. The schedule helps in
optimizing the utilization of sewing resources and
meeting production deadlines.
Key points in creating an effective sewing schedule include:
Operation Sequencing: Determine the optimal order of sewing operations to
maximize efficiency and minimize production time.
Workstation Assignment: Assign tasks to specific workstations based on operator
skills, machine capabilities, and garment complexity.
Time Allocation: Allocate appropriate time for each sewing operation, considering
factors like task complexity and desired output.
Bottleneck Management: Identify potential bottlenecks in the sewing process and
allocate resources accordingly to ensure smooth workflow.
Quality Control Checks: Incorporate checkpoints for quality control to maintain
garment quality throughout the sewing process.
Work-in-Progress Tracking: Implement systems to monitor work-in-progress,
enabling real-time tracking of production status and timely adjustments.
Cutting Schedule
The cutting schedule is a plan that defines the timing and sequence of cutting
operations for different garment styles.
It considers factors such as fabric type, marker efficiency, cutting machine
availability, and cutting order. A well-organized cutting schedule helps
minimize material wastage and streamline the cutting process.
Key points in developing a cutting schedule include:
Fabric Allocation
Equipment and Labor Assignment
Optimal Batch Sizes
Sequencing
Quality Assurance
Fabric Delivery Schedule
The fabric delivery schedule outlines the timeline and quantities for the delivery of
fabric to the production facility.
It aligns with the cutting schedule and production timelines to ensure that fabric is
available when needed for cutting. Efficient fabric delivery scheduling prevents
delays and disruptions in the production process.
Key points in developing fabric delivery include:
Supplier Coordination: Coordinate with fabric suppliers to ensure timely deliveries.
Lead Time Management: Factor in lead times for procurement, shipping, and
customs clearance.
Storage Preparation: Arrange storage facilities for fabric upon arrival, optimizing
space and accessibility.
Production Alignment: Schedule fabric deliveries in sync with production
requirements to avoid delays.
Economic Cut Quantities Calculation
Economic cut quantities calculation involves determining the optimal
quantity of fabric to be cut for each garment style to minimize fabric waste
and production costs.
Factors considered in this calculation include marker efficiency, fabric
width, garment specifications, and cutting constraints.
The goal is to achieve the highest yield of garments from the fabric while
reducing
Key points for economic cut quantities calculation:
Marker Efficiency: Aim for high marker efficiency by optimizing the layout
of garment pieces on the fabric to reduce waste.
Fabric Width and Pattern: Consider the fabric width and garment pattern
to determine how many pieces can be efficiently cut from a given width.
Production Quantities: Base the calculation on the required production
quantities to ensure accurate allocation of fabric for each order.
Wastage Reduction: Minimize fabric wastage by aligning patterns
strategically and utilizing remnants effectively.
Quality control in cutting section
1. Fabric Quality Inspection
After receiving fabric from the store by cutting section, cutting quality inspector check the following
fabric information. If all information is correct, then proceed to the next step. The information are-
✔ Roll to roll fabric shade group check
✔ Fabric GSM and diameter check
2. Marker Quality Inspection
If all information about fabric is correct, the marker quality inspection is run. Marker inspection may
run a parallel way for saving time. Generally, the subjects of marker quality inspection checking
points are-
✔ Marker length and width
✔ Marker efficiency and consumption
✔ Marker type
✔ Lay quantity
✔ Marker ratio
✔ All individual parts of garments are marked in marker
Continue…..
3. Spreading Quality Inspection
If all information of the marker is correct, the spreading quality inspection is started. The
subjects of spreading quality inspection checking points are-
✔ Checking the number of lay as it should not exceed the standards.
✔ Lay ends check
✔ Lay tension check
✔ Lay height check
✔ Lay length check
✔ Check as the marker is best fitted to lay
4. Cutting quality Control
After spreading activity cutting is started if there is no relaxation issue. If fabric needs to relax, cutting
activity is started after relaxing the fabric. The main checking points during cutting is-
✔ Checking cut panel accuracy with pattern
✔ Rightly cutting of lay edge checking.
✔ Checking size mixing
Continue…..
5. Cut Panel Quality Inspection
After cutting the lay, need to check the cut panel before final bundling and
sending to cutting rack. The most important quality checkpoints for the cut
panel are-
✔ Pattern check
✔ Shade check
✔ Size wise ratio check
✔ Fabric check (Spot, Hole, Knot, Slab, Contamination, Lycra out etc.)
✔ If fabric is stripe, checking the strip mismatch
✔ Bundle check
