Clothing Cutting Management: A Comprehensive Guide from Scheme Development to Automatic Cutting Machine Operation

Cutting is an important part of cost management in clothing production, and different schemes can affect material consumption, cost, as well as the shape and quality of the cut pieces. Cutting work plays a crucial role in clothing production. It is not only an important part of enterprise cost management, as different cutting schemes can lead to significant differences in material consumption, which in turn affects the high or low cost of product materials. Meanwhile, cutting is also the primary step in shaping materials, which directly determines the shape and size of the cut pieces, laying the foundation for subsequent clothing production.

In the management process of clothing cutting, we should always pay attention to the key "details". These details are not only related to material conservation and waste, but also directly affect the final quality of the cut pieces. By carefully controlling these details, we can ensure the quality of the cut pieces while achieving the rational use of materials, thereby contributing to the cost management of the enterprise.

01. Details of Developing Cutting Plans

When formulating a cutting plan, it is necessary to consider factors such as the specifications of the cutting machine and blade, fabric characteristics, number of workpieces, and worker efficiency, in order to achieve effective utilization of materials. The development of a cutting plan is crucial as the starting point for cutting work. It involves the detailed decomposition of parameters such as the number of nesting parts, specifications, and laying layers in the production task order. In theory, each production task order can derive multiple cutting schemes, but in practice, enterprises must consider the following key details comprehensively:

Firstly, the length of the cutting bed and the effective cutting height of the cutting blade are the core considerations. The length of the cutting bed limits the maximum length of the discharge, while the height of the cutting blade determines the number of layers of fabric to be laid.

Secondly, the performance of the materials is also crucial. The recoverability, thickness, and surface smoothness of materials directly affect the length and number of layers of the fabric. For example, for silk fabrics, due to their characteristics, the number of layers should not be too many to ensure precise cutting.

Furthermore, the number and specifications of the discharged materials are also important aspects that cannot be ignored. Increasing the number of nesting pieces can save fabric to some extent, but too much can increase the complexity of nesting, which may affect the quality of the fabric and even cause color differences in the cut pieces.

In addition, the labor intensity and efficiency of workers are also factors that must be considered when formulating plans. With the development of fabric laying machines and automatic cutting systems, although the degree of automation has improved, the reasonable allocation of tasks between workers and machines, the full utilization of equipment efficiency, and the reduction of worker burden are still indispensable considerations.

Finally, the full utilization of materials cannot be ignored. Especially for expensive clothing fabrics, how to plan the laying length reasonably when formulating the plan to reduce the waste of broken materials is a key link to enhance the value of materials.

02. Key points for laying and arranging materials

When laying and arranging materials, it is necessary to arrange them reasonably based on the effective width of the material, to meet the requirements of the yarn direction and the alignment of the strips and grids, and to improve the utilization rate of materials to create profits for the enterprise. Laying and arranging materials refers to placing the cut samples tightly within the specified width of the fabric according to the production process requirements, aiming to achieve efficient cutting and material conservation. This process can use manual or CAD nesting techniques, but regardless of the method used, the following points should be emphasized:

Firstly, it is necessary to arrange the materials reasonably based on the actual effective width of the fabric. The recoverability of materials and factors such as woven fabric edges can affect the actual usable width of the discharge. Therefore, enterprises need to carefully plan according to the characteristics of the cut pieces and production needs.

Secondly, it is necessary to ensure that the cut meets the yarn orientation requirements. During the cutting process, the placement direction of the cut pieces must be consistent with the specified yarn direction to avoid adverse effects on the shape of the finished garment and irreversible quality problems. For example, the front placket of the top should align with the warp direction.

In addition, for cutting pieces that require special processing, such as strip to grid cutting pieces, they must be placed in the same circular pattern during discharge. This ensures that the left and right front panels of the top can meet the requirements of the stripes when placed relative to the front placket.

Meanwhile, pursuing high discharge utilization rate is a key goal for enterprises. The materials saved in the discharge process are directly converted into profits for the enterprise. Therefore, enterprises usually measure the effectiveness of material discharge work by the utilization rate of material discharge. The utilization rate of discharge refers to the ratio of the area occupied by the cut pieces to the total area of the fabric. On the premise of ensuring the quality of the cut pieces, the discharge personnel should continuously try to optimize the discharge plan to obtain a more efficient discharge diagram. For manual cutting, it is also necessary to consider the convenience of the cutting staff and plan the cutting path reasonably to ensure the cutting quality.

03. Standardized operation of automatic cutting machine

1) Operating procedures and precautions

Before using the automatic cutting machine, it is necessary to familiarize oneself with the equipment operation, ensure that the gas and power sources are normal, and maintain a safe distance between personnel and equipment. Follow the manual steps during operation to ensure safety. With the improvement of automation in the clothing industry, automatic cutting machines have become essential equipment for many enterprises. However, many enterprises lack a set of systematic operating standards during the use process. For this purpose, we have compiled the following standardized operating procedures for automatic cutting machines, aiming to provide practical reference for relevant enterprises.

1、 Before starting to use the automatic cutting machine, it is essential to thoroughly familiarize and understand its core functions and functions. Only after professional training and ensuring that the operation is qualified, can actual operation be carried out.

2、 During the operation, it is necessary to strictly follow the steps and guidelines in the user manual.

3、 Firstly, check the air source and confirm that the compressed air switch is turned on, while ensuring that the power switch is in the appropriate position. Next, start the computer and enter the relevant commands to enter the desktop operating system. When cutting, it is necessary to ensure that personnel and other materials maintain a sufficient safe distance from the cutting bed to ensure safe operation.

4、 Select the pattern to be cropped through the menu and perform the cropping operation in the order of the queue. Before each cutting, the cutting area should be carefully checked to ensure the accuracy of the cutting.

2) Maintenance and upkeep standards

Automatic cutting machines require regular maintenance, including cleaning, lubrication, and replacement of components, to ensure stable operation of the equipment and compliance with safety regulations to ensure safe operation. Automatic cutting machines require regular maintenance and upkeep to ensure their continuous and stable operation. This includes cleaning the surface of the cutting bed, inspecting and tightening screws, lubricating mechanical components, etc. Regular maintenance can extend the service life of the cutting bed and improve its work efficiency.

When operating the automatic cutting machine, corresponding maintenance and repair work should be carried out according to the computer prompts or when the green light is on. This includes replacing the blade (according to software calculation of blade wear value prompts or visual inspection), replacing the sharpening stone (German Kuris computer prompts), lubricating the tool holder components and moving blocks, and cleaning the filter bucket once a week to ensure the continuous and stable operation of the machine tool.

When repairing and maintaining the automatic cutting bed, it is important to pay attention to safety precautions. Ensure that personnel and other materials maintain sufficient safety distance from the cutting bed, follow operating procedures to ensure their own and equipment safety.
