2. The development of cutting methods
2.1 The origin and development of manual cutting
Manual cutting is a long history of cutting methods, which accompanies the development of human civilisation. In ancient times, in order to meet the basic needs of life, such as making clothes and leather goods, people began to use simple tools for hand tailoring. With the passage of time, hand tailoring techniques have been continuously developed and improved, gradually forming a more mature craft system. In the traditional tailoring industry, manual tailoring requires the tailor to have a wealth of experience and superior skills, and they are able to produce a variety of well-fitting and exquisite garments by measuring, drawing samples and cutting fabrics by hand.
However, manual tailoring also has some obvious limitations. Firstly, its efficiency is low and limited by the speed and physical strength of manual operations, making it difficult to meet the demands of mass production. Secondly, the precision of cutting is often affected by human factors and is prone to errors, resulting in uneven product quality. In addition, manual cutting requires high operator skills, and it takes a long time and cost to train a skilled cutting worker.
2.2 The Birth and Evolution of Automatic Multi-layer Cutting Machine
With the advancement of the industrial revolution and the continuous progress of science and technology, automation technology has been gradually applied to the field of cutting.In the middle of the 20th century, the rise of computer technology laid the foundation for the automation development of cutting equipment. Automatic multi-layer cutting machine came into being, it will be computer technology, numerical control technology and mechanical transmission technology combined to achieve the cutting process of automation and intelligence.
The initial automatic multi-layer cutting machine function is relatively simple, can only complete some basic cutting tasks. However, with the continuous innovation and development of technology, modern automatic multi-layer cutting machine has higher precision, faster speed and stronger functions. For example, some advanced automatic multi-layer cutting machines adopt advanced laser cutting technology, ultrasonic cutting technology, etc., which can realise high-precision cutting of various complex materials. At the same time, the application of intelligent nesting system and quick plate change function further improves the productivity and flexibility of the cutting machine.
3. Multi-dimensional Comparison of Automatic Multi-layer Cutting Machine and Manual Cutting
3.1 Efficiency and Capacity
3.1.1 High-efficiency Operation Mechanism of Automatic Multi-layer Cutting Machine
The automatic multi-layer cutting machine adopts advanced numerical control technology and mechanical transmission system, which is capable of realising high-speed and high-efficiency cutting operations. Its working process mainly includes the following steps: firstly, the operator inputs the designed cutting pattern and parameters into the computer control system; then, the control system automatically generates the cutting path according to the input information and controls the cutter to cut in accordance with the path; in the process of cutting, the cutting machine is able to automatically complete the operations of feeding, cutting and collecting materials without manual intervention.
This automated work mode greatly improves production efficiency. Taking the garment industry as an example, some intelligent cutting systems support a single person to operate independently, and the output can be as high as 60 sets in a single day, while the single-day output of manual cutting is usually around 10 – 20 sets. In addition, automatic multi-layer cutting machines are also capable of continuous and uninterrupted cutting operations, reducing production stoppages due to factors such as manual breaks and operational errors, and further increasing production capacity.
3.1.2 Constraints on manual cutting efficiency
Manual cutting is limited by the speed and physical strength of manual operation, and the cutting efficiency is relatively low. In the cutting process, workers need to manually carry out operations such as measuring, drawing samples and cutting fabrics, which are not only cumbersome but also prone to errors. At the same time, manual cutting will also take a lot of time in the layout, looking for samples, etc., which further reduces the overall production efficiency.
For example, when carrying out mass production, manual nesting requires workers to spend a lot of time and energy to rationally arrange the cutting position of fabrics to improve material utilisation. Moreover, in the event of a nesting error, the nesting needs to be repeated, which can lead to delays in the production schedule. In addition, workers are easily fatigued during the long cutting process, which affects the cutting speed and quality.
3.2 Accuracy and Quality Standards
3.2.1 High-precision Cutting Guarantee of Automatic Multi-layer Cutting Machine
The automatic multi-layer cutting machine is equipped with high-precision cutting capability, which ensures that the size and shape of the cuts are in full compliance with the design requirements. This is due to its advanced numerical control system and precision mechanical transmission device. The CNC system can accurately control the movement trajectory of the cutting knife and the cutting depth, and the error can be controlled within a very small range.
In the cutting process, the cutting machine will cut according to the pre-input design pattern and parameters, without interference from external factors, avoiding errors caused by human factors. This high-precision cutting process can not only improve the overall quality of the product, but also enhance the stability and reliability of the product. For example, in the cutting of automotive interior parts, high-precision cutting can ensure that the size and shape of the interior parts are perfectly matched with the design requirements of the car, which improves the installation accuracy and aesthetics of the interior parts.
3.2.2 Unstable factors of manual cutting accuracy
Due to the existence of human factors, manual cutting accuracy is often difficult to ensure. Workers may be affected by vision, physical strength, emotions and other factors in the cutting process, resulting in deviations in cutting size and shape. In addition, manual cutting uses relatively simple tools, such as scissors and rulers, etc. The limited precision of these tools will also affect the precision of cutting.
For example, when cutting some fine patterns or small-sized parts, manual cutting is prone to problems such as imprecise cutting and easy burrs. These problems will not only affect the appearance quality of the product, but may also affect the performance and life of the product. In the apparel industry, if the cutting precision is not enough, it will lead to ill-fitting sizes, affecting the comfort and aesthetics of wearing.
3.3 Material Utilisation and Cost
3.3.1 Optimised Material Utilisation of Automatic Multi-layer Cutting Machines
Automatic Multi-layer Cutting Machines are able to minimise the generation of waste and improve material utilisation by optimising the cutting programme. Its intelligent nesting system can automatically generate the optimal cutting plan according to the size and shape of the fabric to maximise the utilisation of the fabric.
For example, when cutting garments, the intelligent nesting system will take into account the texture, pattern and cutting direction of the fabric, and reasonably arrange the position of each cut piece to avoid unnecessary waste. At the same time, the cutting machine is also capable of mixing and nesting fabrics of different sizes and shapes to further improve material utilisation. This way of optimising material utilisation not only reduces production costs, but also helps to achieve sustainable development.
3.3.2 Material Waste Problems of Manual Cutting
In terms of material utilisation, there is often a large waste in manual cutting. As it is difficult to precisely control the cutting path and size of manual cutting, it is easy to produce more waste and trimmings. Moreover, manual nesting is less efficient and it is difficult to find the optimal cutting solution in a short period of time, which leads to poor utilisation of fabrics.
For example, when cutting some irregularly shaped parts, manual cutting may produce a large amount of scrap because it is difficult to measure and cut accurately. In addition, workers may have inaccurate cutting dimensions during the cutting process due to operational errors or inexperience, resulting in wasted materials. These wastes and trimmings not only increase the production cost, but also put some pressure on the environment.
3.4 Labour Intensity and Skill Requirements
3.4.1 Automatic Multi-layer Cutting Machine Reduces Labour Intensity and Skill Threshold
The automated operation of automatic multi-layer cutting machine reduces labour intensity. The operator only needs to input the design pattern and parameters into the computer control system, and the cutting machine will be able to automatically complete the cutting process without heavy manual operation. This greatly reduces the labour burden of workers and improves working comfort.
At the same time, the requirements for operators are relatively low. Apprentices can operate the equipment after simple training, reducing recruitment difficulties and training costs. Operators only need to master the basic computer operating skills and the operating procedures of the equipment to be able to operate the cutting machine proficiently. Moreover, with the continuous development of cutting machine technology, some cutting machines are also equipped with self-diagnosis and automatic alarm function, which further reduces the requirement for operator’s skills.
3.4.2 High Labour Intensity and Skill Dependence of Manual Cutting
Manual cutting is more labour-intensive, and workers need to stand for a long time and hold the tools for cutting operation, which is easy to lead to physical fatigue and injury. Moreover, the requirements for operators are high, and workers need to have certain cutting skills and experience to be able to do the job.
It takes a long time and cost to train a skilled cutting worker. Workers need to master a variety of skills, such as measuring, drawing, and cutting, and they need to accumulate experience in practice in order to achieve a high level of cutting. In addition, since the quality and efficiency of manual cutting depends to a large extent on the skill level of the workers, companies need to invest a lot of effort and resources in recruiting and training cutting workers.
3.5 Flexibility and Adaptability
3.5.1 Flexible and Diverse Adaptability of Automatic Multi-layer Cutting Machines
Automatic multi-layer cutting machines support a variety of cutting patterns and pattern designs. Its computer control system can store a large number of cutting patterns and parameters, and the operator only needs to change different cutting patterns and patterns through simple operation.
At the same time, it also has a quick-change function, which can quickly adapt to the cutting needs of different products. When it is necessary to change the cutting pattern or size, the cutting machine can complete the switching and adjustment of the programme in a short period of time without the need for complicated mechanical adjustments and re-layout. This flexibility and adaptability makes the automatic multi-layer cutting machine able to meet the individual needs of different customers and improve the market competitiveness of enterprises.
3.5.2 Flexibility Limitations of Manual Cutting
In terms of flexibility and adaptability, manual cutting is relatively weak. Once the cutting pattern or size needs to be changed, it is time-consuming, labour-intensive and inefficient to re-layout and test cut. Workers need to redraw the pattern according to the new pattern and size, and then carry out trial cutting to ensure the accuracy of cutting.
Moreover, manual cutting has limited ability to cut complex patterns and shapes, which makes it difficult to meet customers’ individual needs. For example, when cutting some fabrics with special textures or patterns, manual cutting may not be able to achieve the desired results. In addition, the speed and efficiency of manual cutting varies greatly from one cutting task to another, making it difficult to achieve rapid production changeover.
