Definition:- cut order planning is the process that seeks to minimize to tootle production costs through planning and management of pre production operations .

ding the most effective match ofefficient nestsfor aspecific cutting orderpresents a challenge for even thebest cut planners. Accounting for the thousands of variables and possible solutions exceeds human capabilities but not the optimizing capabilities ofCUTPLAN.

Leveraging our advanced algorithms,CUTPLAN will automatically simulate all possible combinations ofexisting and new nestsfor each cut to find the one that best optimizes your exact production requirements.CUTPLANis currentlysaving 2% - 8% of material costs for many top manufacturers

Advantage of using cut order plane

Material cost/cutting cost balancing Save time in cut planning, spreading and cutting, free-up time for more value-added tasks Plan within material availability by length and width, various stock sizes Full reporting to production control, nesting, and/or cutting room floor Eliminate all manual cutting paperwork Easy updating, viewing and printing of government and other long-term contracts, showing quantities cut and quantities outstanding by month, product, and size

06) Write a comprehensive note on computerized maker making technology?

In todays world Textile Industry apparel are being modernized day by day. Now a day, the designs are used in different textiles manufacturing processes. Computerized marker making method marker, designing and plotting doing by computer and computer related equipments .now computerized maker making method is a most commend marker making method using in garment industry.

What are the equipments of using to computerized marker making?

Relevant Computer Plotter Additional digitizer table Relevant Computer software (Gurbur, TOka,Lectra)

Advantages and important of using to computerized marker making1. Pattern grading vary easy if we use manual grading we have to spent lot of time and we cant satisfy accuracy of manual grading. But when we use computerized pattern making we can enter details to software and can grad several sizes quickly and correctly. 2. Computerized marker making has 1%-3% efficiency than manual marker making

Efficiency going up mean fabric saving also going up. It is very important thing because normally 60%-70% of total garment cost goes to raw fabric. If we use Computerized marker making we can reduce garment cost.

3. 20% time saving has more than manual maker making if using manual methods they have to draw marker using pattern pieces but if use computerized method we can make maker using computer. That time computer displayed efficiency, length, width like details. After make maker it send to plotter and can print it very easy.

4. Can store and old makers vary easy After make maker it send to plotter but normally computer operator save it in that computer. We are going to store manual marker we want lot of space. Some time repeating styles comes to factory some time old makers very useful 5. Can use one maker again and again If they have large quantity cutting room have to make several makers one special thin of computerized pattern making they can print lot of copies from one maker.

6. Can provide higher quality garmentsNo overlapping, can decide minimum distance and shape are very correct. Cutting operators can cut easily

7. Can match stribe fabric and chek fabric

8. You can ingrigreat with other cutting machines wecan send maker to cutter and cutter cutting pieces very correctly

Disadvantages 1. Basic invest vary higher because this machine and software very expensive2. Maintain cost higher 3. If break down waiting time long. It is big issue to continue production. 4. Higher skill operators5. Have to update software. Update also very expensive 10) Write a short note on the spreading method

Mainly spreading method can divide in to two groups 1. Manual spreading 2. Machine spreading

Manual spreading

Manual spreading was doing by minimum two operators .time consuming process . the operators should have to maintain laying correct tension . they use mainly two spreading techniques to minimize to that affect 1. Pulling techniques :- suitable for woven fabrics and non elastic fabrics 2. Pushing techniques :-suitable for elastic fabrics and stretchable knit fabrics.

Advantages of manual spreading

1. Can spread stretchable knit fabrics, stripe fabrics , checks fabrics When spread stripe and check fabric operators use some techniques 2. Can minimized spreading defects 3. Can identify some fabric defects

Disadvantages of manual spreading4. time consuming process5. efficiency and spreading speed low machine spreading firstly in this method fabric roll fixed to the spreading machine. There are lot of machine brands available in market. Operator can enter details to the spreading machine. The fundamental purpose of spreading machines is to superimpose layers of fabric in a smooth.

Advantages of machine spreading 1. spreading speed higher than manual speeding method2. have higher efficiency 3. low labor cost Disadvantages of manual spreading1. basic invest vary higher 2. Maintain cost higher 3. If break down waiting time long. 4. Higher skill operators

14)Explain the process, advantages and disadvantages of computerized cutting process

Maker makingCutting processSpreading Pattern making

Now apparel industry move with new technologies lot of companies use computerized cutting methods. Using this method can achieve required shapes productivity like things .but Should need a opera to feed the data and should use correct software .After make maker in manual method have to get several copies and paste on upper lay of layers and cut suing manual machine. But in new technology marker making computer and the cutting machine has direct link. After make marker operator can send it to the cutter start cutting process

Advantages

1. Higher efficiency and productivity If we use other machine( straight knife like that machine )difficult to cut small pieces. canot cut small pieces and small shape. that mean wastage high. but use in this method wastage low and can achieve higher efficiency. 2. Can cut many layers in one time 3. Can increase notches 4. Machine has display and it displayed many details .5. Better cutting quality than other machines 6. Quality of cutting not depend on the skill of the operator 7. Low fabric wastage and could cut any shape8. The cutting machine is moving though the marker and cut automatically Disadvantages

1. Machines are more expensive2. If there is any trouble it will take more time to mend it 3. Should want knowledgeable operators to enter the data to computer

15) Find out the new developments in computerized cutting technology. prepare a comprehensive note

1) Computer controlled knife cutting2) Cutting by Laser beam3) Cutting by Water jet4) Cutting by Plasma torch

Computer controlled knife cutting:

The latest computer aided cutting systems, pattern design, grading and marker making software has been enhanced to improve productivity, simplify workflows and generate more accurate material costs. Special feature of computer controlled cutting system can make high efficiency markers and send it to knife and it able to cutting fabrics pieces correctly and quality.

Advantage:

Very active & fast cutting by computer controlled system.

Suitable for verylarge-scale production.

Speed of cutting canbe controlled.

Cutting defects are less than other.

-Less labor cost

No need of marker paper.

Disadvantage:

Need to necessary software it was very expensive .have to update software If any breakdown repair time is long Need knowledgeable operator -Very expensive machine. Higher maintenance cost.

Water jet cutting:

also known as awaterjet,is a tool capable of slicing intometalor other materials (such asgranite)using a jet ofwaterat high velocity and pressure, or a mixture of water and anabrasivesubstance. The process is essentially the same aswater erosionfound in nature but greatly accelerated and concentrated. It is often used during fabrication or manufacture of parts for machinery and other devices. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods

Advantage:

Very fast cutting operation

Not require to sharp the blade

Disadvantage:

Capital costs are high

Water is to be filtered and de-ionized

Laser cutting

In the world of industrial and technical textiles, laser cutters are often the only choice for high production speeds on difficult materials.There are two main advantages to laser cutters over blade cutters.1. Laser cutter do not touch the fabric. This means that many types of difficult material can be easily cut without problems, which could lead to waste or ruined fabric.2. Laser cutters can edge seal fabric while it is being cut. The edge seal will stop fraying and can eliminate a hemming or separate edge-sealing operation.Aeronaut manufactures two ranges of innovative gantry-mounted laser cutters with either a lightweight chassis or a heavier dual gantry chassis for carrying larger, heavier lasers

Disadvantage:-

Not suitable for cutting multi layer offabric Not suitable for synthetic fabricPossibility ofburning

Plasma cutting

Plasma cutting machines uses a high-frequency, high-voltage spark to ionise the air through the torch head and initiate an arc. These require the torch to be in contact with the job material when starting, and so are not suitable for applications involving fabric cutting
