With the continuous progress of science and technology, fully automatic multi-layer fabric cutting machine came into being. With advanced technology and automated operation mode, it can significantly improve the quality and efficiency of cutting, and bring revolutionary changes for garment production. In-depth study of the basic operating procedures of automatic multi-layer fabric cutting machine is of great practical significance to improve the production efficiency of garment manufacturers, reduce production costs and improve product quality. By standardising and optimising the operation process, the performance advantages of automatic multi-layer fabric cutting machine can be given full play to, and the garment industry can be promoted to the direction of intelligent and efficient development.
1.2 Development Status of Automatic Multi-layer Fabric Cutting Machine
In recent years, the technology of automatic multi-layer fabric cutting machine has developed rapidly. With the continuous progress of computer technology, sensor technology, automation control technology, etc., the function of automatic multi-layer fabric cutting machine is more and more powerful, and the performance is more and more stable. At present, there are many brands of automatic multi-layer fabric cutting machine on the market, and there are some differences in functions, precision, speed and other aspects of different brands and models of cutting machines. Some high-end automatic multi-layer fabric cutting machines are equipped with advanced cutting technology, intelligent nesting system and efficient vacuum adsorption device, which can meet the needs of different customers.
At the same time, with the improvement of environmental protection consciousness, some automatic multi-layer fabric cutting machine also adopts energy saving and environmental protection design concept, which reduces energy consumption and impact on the environment. However, although the automatic multi-layer fabric cutting machine technology has made great progress, but in the practical application, there are still some problems, such as complex operation, high maintenance costs, operators with insufficient skill level, etc. These problems restrict the further promotion and application of automatic multi-layer fabric cutting machine.
Advantages of Automatic Multi-layer Fabric Cutting Machine
2.1 Comparison with Traditional Manual Cutting
2.1.1 Cutting Quality
Traditional manual cutting mainly relies on the experience and skills of the workers, and due to the human factor, hand errors are difficult to avoid. In the process of cutting, workers may be fatigue, lack of concentration and other reasons for cutting size deviation, lines are not smooth and other problems, thus affecting the overall quality of the garment. The fully automatic multi-layer fabric cutting machine adopts advanced CNC technology and high-precision cutting tools, which can accurately carry out cutting according to the preset procedures, with minimal cutting size error and smooth and neat lines, which greatly improves the cutting quality.
2.1.2 Accuracy
Manual cutting has great difficulties in ensuring accuracy, especially for complex patterns and fine cutting requirements. Due to the limitations of manual operation, it is difficult to ensure that the cutting size of the upper and lower layers of fabrics is exactly the same, and this error will be more obvious in large quantities and multi-layer cutting tasks. However, the automatic multi-layer fabric cutting machine, through the precise positioning system and cutting control technology, can ensure that the cutting size of each layer of fabric is accurate, and the size error of the upper and lower layers is almost negligible, thus ensuring the consistency and accuracy of the products.
2.1.3 Production efficiency
Manual cutting is slow and labour-intensive, which requires a lot of manpower and time for large-volume cutting tasks. The automatic multi-layer fabric cutting machine, however, is characterised by high speed and high efficiency, and is able to complete a large number of cutting tasks in a short period of time. At the same time, the automatic operation of the cutting machine reduces manual intervention, improves production efficiency and reduces production costs.
2.2 Principle of Enhancing Cutting Efficiency
The principle of enhancing cutting efficiency of automatic multi-layer fabric cutting machine is mainly reflected in the following aspects. Firstly, it adopts an advanced numerical control system, which can quickly and accurately read and process the cutting file, and automatically control the movement trajectory and speed of the cutting tool according to the instructions in the file, so as to realise efficient cutting. Secondly, the cutting machine is equipped with high-speed cutting tools, such as laser cutting head and vibrating knife, etc. These cutting tools are characterised by fast cutting speed and high cutting quality, which can greatly shorten the cutting time. In addition, the automatic multi-layer fabric cutting machine also has an intelligent layout function, which can automatically optimize the layout scheme according to the size and shape of the fabric, maximize the utilization rate of the fabric, reduce the waste of the fabric, and thus improve the production efficiency.
2.3 Guarantee of the quality of garment production
The guarantee of the quality of garment production by automatic multi-layer fabric cutting machine is mainly reflected in the following aspects. On the one hand, the precise cutting size ensures the accuracy of the size of each part of the garment, so that the garment can be better matched and spliced in the sewing process, reducing the errors and adjustments in the sewing process and improving the overall quality of the garment. On the other hand, the smooth and neat cutting lines make the edges of the garment more beautiful, reduce the difficulty and workload of subsequent processing, and improve the appearance quality of the garment. In addition, the stability and reliability of the automatic multi-layer fabric cutting machine also ensures the consistency of the cutting quality, avoids the quality fluctuation caused by human factors, and improves the qualified rate of the products.
Preparation and inspection work before operation
3.1 Cleaning and lubrication of cutting machine

At the same time, it is also necessary to check whether the grounding of the cutting machine is good to ensure the safety of the operator.
3.3 Inspection of mechanical components
The normal operation of mechanical components is the key to enable the automatic multi-layer fabric cutting machine to cut accurately. Before operation, it is necessary to check the mechanical parts, including checking whether the installation of the cutting tool is firm, whether the wear and tear of the tool is serious, whether the connection of the transmission parts is loose, and whether the flatness and perpendicularity of the guide rail meet the requirements. If mechanical parts are found to have problems, they need to be repaired or replaced in time to ensure the normal operation of the cutting machine.
3.4 Software system check
The software system is the control core of the automatic multi-layer fabric cutting machine, and its normal operation is directly related to the cutting accuracy and efficiency of the cutting machine. Before operation, it is necessary to check the software system, including checking whether the software can start normally, whether the cutting file can be read and processed normally, and whether the parameters of the software are set correctly. If the software system is found to have problems, the need for timely repair or update to ensure the normal operation of the cutting machine.
The start of the cutting machine and software operation
4.1 Power switch on and unlock operation
After completing the preparation and inspection work before operation, the staff can turn on the power to start the automatic multi-layer cutting machine. When switching on the power supply, it is necessary to pay attention to the correct order of operation, first open the main power switch, and then open the control power switch of the cutting machine.
Most fully automatic multilayer cutting machines require an unlocking operation on the operating panel before the machine can continue to operate. The unlocking operation usually requires the entry of the correct password or the use of a specific unlocking card to ensure that only authorised personnel can operate the cutting machine. Some software programmes also need to be unlocked accordingly in order to activate the full functionality of the software.
4.2 Opening of Software Programmes
After completing the unlocking operation of the cutting machine, it is necessary to open the corresponding software programmes in the computer. The software programme is the control centre of the automatic multi-layer fabric cutting machine, through which various operations and control of the cutting machine can be realized. When opening the software programme, it is necessary to pay attention to whether the version of the software matches the model of the cutting machine, and whether the software has installed the necessary drivers and plug-ins.
4.3 Cutting File Design and Import
4.3.1 Cutting File Design
The design of the cutting file can be specified by the manufacturer or designed and drawn by yourself. If you choose to design and draw the cutting file by yourself, you need to use professional garment design software, such as AutoCAD, CorelDRAW, etc.. When designing the cutting file, it is necessary to draw accurately according to the style, size and cutting requirements of the garment to ensure the accuracy and completeness of the cutting file.
4.3.2 Format Conversion and Saving of Cutting File
The designed cutting file needs to be converted and saved into a format that meets the requirements before it can be imported into the system software of the automatic multi-layer cutting machine. Common cutting file formats include DXF, PLT and so on. In the format conversion, you need to use the appropriate conversion tools to ensure the accuracy and compatibility of file conversion.
4.3.3 Cutting file import and parameter setting
After the converted and saved cutting file is imported into the system software of the automatic multi-layer cutting machine, it is necessary to edit, adjust and set the corresponding parameters. These parameters include cutting speed, cutting pressure, tool type, number of layers to be cut and so on. Parameters need to be set according to the material of the fabric, thickness and cutting requirements for reasonable adjustment to ensure that the cutting effect is optimised.
Preparation and Placement of Fabric
5.1 Selection and Finishing of Fabric
Before carrying out the cutting work, it is necessary to select suitable fabric. The choice of fabric needs to be considered according to the style, use and quality requirements of the garment. The fabric also needs to be finished, including checking the quality, flatness and colour consistency of the fabric, and removing stains and imperfections from the fabric.
5.2 Fabric transfer
The fabric with the perforated paper is transferred to the corresponding cutting area of the automatic multi-layer cutting machine. The transfer of the fabric can be carried out by the fabric transfer system of the cutting machine or manually. During the transfer process, attention should be paid to the flatness and tension of the fabric to avoid wrinkles and shifts in the fabric.
5.3 Covering of wheat paper and vacuum film
After the fabric is transferred to the cutting area, it needs to be covered with wheat paper on top of the fabric. The purpose of the paper is to protect the surface of the fabric and prevent the fabric from being scratched and contaminated during the cutting process. Finally, the vacuum film is covered. The purpose of the vacuum film is to provide vacuum adsorption force during the cutting process to ensure that the fabric remains stable during the cutting process and to avoid fabric movement and deformation.
5.4 Principle and function of vacuum adsorption
Vacuum adsorption is one of the important functions of the automatic multi-layer fabric cutting machine. The principle is to pump out the air on the cutting table by vacuum pump to form negative pressure, so as to adsorb the fabric tightly on the table. The role of vacuum adsorption is mainly reflected in the following aspects. Firstly, it can ensure that the fabric remains stable during the cutting process, avoiding the movement and deformation of the fabric, thus improving the cutting precision. Secondly, it can reduce the jitter and vibration of the fabric during the cutting process, reduce the cutting noise and improve the comfort of the working environment. In addition, vacuum adsorption can also improve cutting efficiency and reduce cutting time.
Cutting operation process
6.1 Vacuum adsorption work check
Before cutting operation, it is necessary to check the vacuum adsorption work. The inspection includes whether the vacuum degree meets the requirements, whether the vacuum pipeline is firmly connected, whether the vacuum valve is normally open and so on. If the vacuum adsorption work is found to have problems, it is necessary to carry out timely investigation and repair to ensure the stability of the fabric in the cutting process.
6.2 Confirmation of the starting point of cutting
After the vacuum adsorption work, it is also necessary for the staff to aim to confirm the starting point of cutting and the position of the axial direction. The confirmation of the starting point of cutting is very important, which is directly related to the accuracy and consistency of cutting. When confirming the starting point, you need to use the positioning system that comes with the cutting machine or auxiliary tools to ensure the accuracy of the starting point.
6.3 Operations and Precautions in the Cutting Process
6.3.1 Re-alignment in the Cutting Process
Re-alignment is possible in the cutting process. If a slight movement or offset of the fabric is found during the cutting process, or if the cut size is off, it can be adjusted by means of re-alignment. The re-alignment operation needs to be carried out on the operation panel of the cutting machine, and the corresponding operation can be carried out according to the prompts.
6.3.2 Over-window point-to-point operation
Until a cutting window is completely finished, the next window can be cut by over-window point-to-point. Fully automatic multi-layer cutting machine because of the technical support, the entire window to point work can be carried out more quickly and efficiently, to maximise the cutting efficiency of fully automatic multi-layer cutting machine. In the operation of window pointing, attention needs to be paid to maintaining the stability and accuracy of the cutting machine to avoid errors.
6.3.3 Monitoring in the cutting process
In the cutting process, the staff needs to closely monitor the operation status of the cutting machine, including cutting speed, cutting pressure, tool wear, etc. If any abnormality is found in the cutting machine, the staff should pay attention to maintaining the stability and accuracy of the cutting machine to avoid errors. If abnormalities are found on the cutting machine, such as excessive noise, abnormal vibration, etc., it is necessary to stop the cutting work in time and carry out inspection and maintenance.
6.4 Processing work after cutting
After cutting is completed, the cutting machine and the cut fabric need to be processed. First of all, turn off the power and software programme of the cutting machine, and clean up the fabric debris and sundries on the surface of the cutting machine. Then, remove the cut fabric from the cutting machine and sort and organise it. Finally, knives and cutting tools are cleaned and maintained to extend their life.
