Fabric cutting machine is very important factor in textile and garments sectors. A good quality garment will be ready first to wear when it will be completed by sewing after cutting fabrics. Many parts of fabric which are cutted by fabric cutting machine in a cutting table in the lay or spread of fabric. The cutting department has the duty of getting the raw material from the store; the raw material is mainly the fabric and interlining, in case of the cutting department. It also has to get the right marker at right time to ensure the smooth running of the department. After the cutting is completed, the cutting department has to dispatch the cut-parts to the sewing department.
List of Cutting Tools:
List of cutting tools or cutting tool is given below-
There arethree types of cutting machine available.
Manual cutting machine:
Die cutting
Drill cutting
Hand operated cutting scissor
Manually operated power knife cutting machine:
Straight knife cutting machine
Round knife cutting machine
Band knife cutting machine
Computerized cutting machine
Knife
Water jet
Laser
Plasma torch
Hand Cutters:
Hand cutters are used to give a small cut to the check fabric after the lay has been spread. This small cut thus made is then torn by the hand and the cutter is not used for the whole width cutting, as cutting throughout can cause the shift of grain and by tearing, the grain does not changes, hence, the cutting of the edge is manual in check fabric.
Cutting Step With Fabric Cutting Machine:
The cutting is done in 3 steps, in the first step, block cutting is done, followed by relaying of the blocks and further cutting it into actual patterns. The spread fabric is cut by 1-3 cutting operators with the help of straight knife fabric cutting machine. The patterns are not given a precise cut at first but are cut into ‘blocks’ that mark the outline of each pattern. The cutting in this section is done for an average of 140 bundles in an hour for a cotton check fabric, though it differs with the type of fabric and the design.
There are a few things which are to be kept in mind while cutting the free fabric lays. These can be listed as
Precision of cut
Clean edges
Unscorched, unfused edges (for polyester fabric)
Support of the lay
Consistent cutting
The marker is placed over the spread fabric and is matched to the ends. The lay is 1” more than the total width and length of the spread. This allowance is left to allow the space for the movement of the cutter. A hole is made in every marker piece of the paper marker by tearing it, this hole is covered by the cello tape and it keeps the marker from moving from its place. The plies are also kept from moving by the side by the use of clips. A straight knife cutter is used for cutting the block patterns. For a spread extending to 14 yards, upto 3 cutters are used for the purpose of cutting tools. The use of more than 1 cutter at a time increases the number of patterns cut in an hour by 3 times. These cutting men are skilled operators in this job, and cut an average of 25 bundles of 234 lays of the 100% cotton fabric.
The block cuts are then taken for the re-laying, which is done for check and stripe matching. The relaying also ensures that the plies of the block are aligned to perfection. Matching the horizontal lines of the check with he horizontal lines on the table does the check matching in this stage; 2 people are used for this purpose. They also make sure that the block patterns are aligned vertically also, by matching their ends. This re-laying is the most time consuming work in the cloth cutting process with fabric cutting machine and also important for the quality purpose as it ensure the matching of the checks and the stripes.
These blocks, after re-laying are taken for the re-cutting. This re-cutting is done with the help of straight knife cutter and also uses the band knife cutter for smaller pieces. The cloth cutting tool man cuts the final pattern but leaves a small protruding area in the bigger parts, like the front and the back to provide an area for numbering.
The fabric is now finally cut into final pattern, which are very much in the stitching condition. All the pieces are then numbered, in the reverse order from the top. The numbered pieces of the same garment, and of the same colored are again grouped together and bundled. This ensues a proper grouping of patterns cut together. This ends the work to be done on the patterns by the cloth cutting tools machine room. The patterns are then dispatched to the sewing room whenever requested.
Protective Cutting ToolsPolicy:
This policy is applicable for the workers and those specific staff who work in particular areas, which are hazardous.

Round cutting knife machine is the most useful cutter knife instrument in apparel industry. Round knife is mainly used for small production. Round knife cutting machine is called round knife cutting machine because its cutter is round but slightly octagonal in shape. Round Knife is basically used for edge cutting while the manual laying or spreading is taking place. It is 200 mm in diameter and has a limitation for not cutting precise at the curve and thus is used for edge cutting as it gives a precise straight line cut. It is used for cutting the plain and stripe fabric, but strictly not for cutting the edge of the check fabric because it causes the problem of bowing if the check fabric gets an off-grain cut.
Function of Round Cutter Knife:
Round cutter knife is widely used to separate the big parts and separate the blocks of fabric from relatively small height fabric lay.
Round knife machine can be easily movement due to light weight.
Round knife machine have manual grinder is used to sharp the blade.
Blade automatic knife is octagonal type & has a very sharp edge.
Fabric lay height can be cut using up to 40 percent of the blade diameter of round knife.

Standard Operating Procedures of Cutting
Cutting: It is the process of effective utilization of fabric by efficient marker making and cutting of garment parts to provide support to business by reducing the Fabric Costs (added due to wastages).
Importance of Cutting: In garment business, Fabric cost covers 60% of the total cost of manufacturing. Thus, it becomes very important to use the fabric efficiently with least wastages. Cutting department can be considered as the most important department for any Factory.
Cutting SOP
Cutting Department: The following processes constitute the Cutting department:
Fabric Relaxation
Spreading and Cutting
Numbering and bundling
Fusing
SOP for Cutting: First of all, the Shade segregation report is referred
After receiving the fabric, it is verified with the Shade report as per CCR, which is prepared by merchandiser by considering the shrinkage rate with shade report.
Fabric relaxation of minimum 48 hours is done for Spandex fabrics
Table preparation is done and fabric Spreading is done. The record for end –bits is kept. During laying, the Q/C continuously checks the fabric and marks the area containing defects. These marked area parts are replaced later on using the same roll end – bits
After spreading, Marker is placed on top of the lay and checking is done by placing hard patterns to avoid any errors of marker, overlapping, grain line and missing parts.
Once, the marker is confirmed to be OK, Cutting is done followed by Cut Panel Audit. Any issues arising are resolved by the Cutting In-charge and defective parts are replaced simultaneously.
Numbering and Bundling is done after cutting to avoid any serial mistakes during sewing (which may lead to panel to panel shade variation).
After Numbering, bundles are sent for Fusing and Printing. The Q/C checks the quality and placement of fusing and printing randomly. Any issues encountered are immediately highlighted and resolved by the Cutting in-charge.
Once, all the quality check points are passed, the cut parts are issued to the Sewing department.
Reports in Cutting Section: Six reports are being made in the Cutting Section:
Fabric Relaxation Record
Marker and Spreading Checking Report
Daily Cut Panels and Bundling Checking Report
Parts Replacement Report
Fusing M/C Temperature and Pressure Checking Report
Fusing M/C Clean Report
Fabric Relaxation Procedure:
Fabric relaxation is very important for fabric having stretch/spandex in nature. This kind of fabric is required to be unrolled and kept for minimum 24 hours to come back to its original shape. Relaxation is vital to keep measurement after cutting consistent.

If snap top side plastic or glass then should be considered for increasing presser and have to adjust a presser that will not damage top side.
Rules to identify about liner of button
As we know,
1 inch = 40 liner
1 inch = 2.54 cm
= 25.4 mm
Liner = 25/ 40 [mm / liner]
= 0.625
Button width = 11 mm
Liner = 11/ 0.625
= 17.60
= 18 [Because after point if the number is bigger than 5 than it counts as 1 and point dismissed]
Rules to set hole at neck and front placket
Rules = front placket width /2 -3 [here 3 mm minus for bartack width]
As rules
If f / placket width = 3 cm = 30 mm
Hole placement of neck will be = (30 / 2 – 3) mm
= 12 mm
If f / placket width = 3.5 cm = 35 mm
Hole placement of neck will be = (35 / 2- 3) mm
= 14.5 mm
Front placket hole placement
Front placket width / 2 = f / plkt hole placement
If , placket width = 30mm
Hole placement will be = (30 / 2) mm
= 15 mm
