基于以上原因，激光切割加工技术在钣金车间应运而生。激光切割加工技术的比较大特点是无需模具即可加工。使用激光切割加工冲裁节省了大量模具的使用，从而缩短了生产时间，降低了产品成本。激光加工技术在市场上的优势更好。它非常有利于多种小批量产品的生产和随后产品的大规模生产。

钣金车间激光器本身是一种高亮度、准确方向性、单色性和平行性的相干光源，其能量密度非常高。当聚焦激光束能够在被照射的材料上产生高温时。在数万度高温的作用下，无论材料有多硬，都会立即熔化蒸发，同时产生冲击波，熔化并去除材料。在激光材料加工过程中，局部加热实质上是熔化形成汽化材料。

钣金车间的激光切割加工技术可以加工传统方法难以实现的零件。例如，对于带有大盒子的钢制零件，需要加工许多不同尺寸的孔，这是传统加工方法无法做到的，而激光切割加工技术可以满足这些要求。即使加工相同的零件，激光切割加工技术也具有精度高、时间短的优点，因此产品具有很强的市场竞争力。

钣金车间的激光切割加工在二维平面上具有很强的灵活性。使用时，工件固定切割机的切割头处于移动状态，不会造成加工死角，相应提高了加工材料的利用率，可以省去设备的微连接，激光切割加工设备更简单。激光切割加工设备的计算机控制系统作为一个整体进行控制，无需单控制零件、设置模具和设计加工路线即可进行相应的加工。因此，可以大大缩短激光切割加工技术的工艺准备时间。激光切割加工设备加工速度快，缩短了加工时间，提高了生产效率。

钣金加工零件的加工步骤有:产品初步试验、产品试生产和产品批量生产。在产品加工的试生产阶段，应及时联系客户，并在获得相应加工的评价后进行产品的批量生产。

钣金车间应及时与客户沟通和讨论，确定的内容包括产品所需的技术目标、技术保密内容的合同、产品专利、设计方案和图纸的管理、相关技术的处理以及产品交付的具体时限。并相应制定合同，明确技术权限和各自的权利。钣金车间应在加工过程中对客户的技术内容保密，以免其产品因侵权而受损。

技术人员接受批量试生产或生产的委托后，应按合同要求的标准进行加工。为确保钣金车间技术人员的专业素质，工作应以快速的工作方式完成，以满足客户的需求。

钣金车间的技术人员应熟悉激光切割加工设备的特点，了解激光切割加工设备的状况，做好设备维护工作。设备在比较佳状态下运行。在激光切割加工过程中，应及时进行目视检查，包括宏观观察和微观观察，观察激光切割的截面形状，并做好相应的信息记录。在激光切割发生器的激光切割加工中心，在激光切割区、计算机控制区、原料进料区、成品下料区和物料转换装置的工作区，需要安排技术人员在原料进料区和成品下料区操作，其他工作区可由计算机自动控制实现自动化。

Based on the above reasons, laser cutting technology emerged in sheet metal workshop. The biggest characteristic of laser cutting technology is that it can be processed without mould. The use of laser cutting and blanking saves the use of a large number of molds, thus shortening the production time and reducing the product cost. Laser processing technology has better advantages in the market. It is very conducive to the production of a variety of small batch products and subsequent large-scale production of products.

The laser of sheet metal workshop is a kind of coherent light source with high brightness, precise direction, monochromatic and parallel, and its energy density is very high. When the focused laser beam can produce high temperature on the irradiated material. Under the action of tens of thousands of degrees of high temperature, no matter how hard the material is, it will immediately melt and evaporate, generate shock wave, melt and remove the material. In the process of laser material processing, local heating is essentially melting to form vaporized material.

The laser cutting technology of sheet metal workshop can process the parts which are difficult to be realized by traditional methods. For example, for steel parts with large boxes, many holes of different sizes need to be machined, which is impossible for traditional machining methods, and laser cutting technology can meet these requirements. Even if the same parts are processed, laser cutting technology has the advantages of high precision and short time, so the products have strong market competitiveness.

Laser cutting in sheet metal workshop has a strong flexibility in two-dimensional plane. When in use, the cutting head of the workpiece fixed cutting machine is in the moving state, which will not cause the dead angle of processing. Accordingly, the utilization rate of processing materials is improved, the micro connection of the equipment can be omitted, and the laser cutting processing equipment is simpler. The computer control system of laser cutting equipment is controlled as a whole, which can be processed without controlling parts, setting mould and designing processing route. Therefore, the preparation time of laser cutting technology can be greatly shortened. Laser cutting equipment has the advantages of fast processing speed, short processing time and high production efficiency.

The processing steps of sheet metal processing parts include: product preliminary test, product trial production and product batch production. In the trial production stage of product processing, the customer shall be contacted in time, and the batch production of the product shall be carried out after obtaining the corresponding processing evalsuation.

The sheet metal workshop shall communicate and discuss with customers in a timely manner, and the determined contents include the technical objectives required by the product, the contract of technical confidential contents, product patents, the management of design schemes and drawings, the treatment of relevant technologies and the specific time limit for product delivery. The contract shall be made accordingly to clarify the technical authority and respective rights. The sheet metal workshop shall keep confidential the technical content of customers in the process of processing, so as to avoid the damage of its products due to infringement.

After the technicians accept the Commission of batch trial production or production, they shall process according to the standard required by the contract. In order to ensure the professional quality of the technicians in the sheet metal workshop, the work should be completed in a fast way to meet the needs of customers.

The technicians in the sheet metal workshop should be familiar with the characteristics of the laser cutting and processing equipment, understand the status of the laser cutting and processing equipment, and do a good job in equipment maintenance. The device is operating at its best. In the process of laser cutting, visual inspection should be carried out in time, including macro observation and micro observation, observing the section shape of laser cutting, and making corresponding information records. In the laser cutting center of the laser cutting generator, in the laser cutting area, the computer control area, the raw material feeding area, the finished product blanking area and the working area of the material conversion device, it is necessary to arrange technicians to operate in the raw material feeding area and the finished product blanking area, and other working areas can be automatically controlled by the computer.
