激光切割VS。等离子切割服务：优化精密 OEM 项目的成本

专注于精密 OEM 切割服务的原因在于对热引起的微变形的可测量控制。反过来，该策略通过避免任何后切割步骤、确保组件适合并满足流程可追溯性的要求来满足客户需求。这种技术推理是专为要求苛刻的情况而定制的，当精密激光切割和可靠的医疗级制造变得至关重要时。

加工 20 毫米重型板材时，激光切割成本与等离子切割相比如何？

选择一种有效的技术来切割 20mm 板材不仅仅是一个经济问题；更是一个问题。这是相当重要的，因为切割质量会影响组件的整体性能以及与整个项目相关的费用。 区分等离子切割与高功率激光切割的主要因素是切割质量，它会影响制造过程的每个阶段。因此，以下解释旨在帮助您在激光切割成本与等离子切割成本之间做出正确选择：

量化割缝质量差异

这一切都始于切割产生的斜角。虽然厚板制造中的切割会产生约1.5°的角度，但我们的高功率激光切割技术将确保斜角不超过0.5°。如果您要使用这些元件进行焊接，这种垂直度控制至关重要。

DFM 干预降低装配风险

执行DFM 分析时我们考虑的主要标准之一是高精度。作为避免制造带有孔或螺纹簇的零件时出现装配问题的有效方法，我们在加工前进行精密激光切割。因此，可以避免由于热量而可能发生的任何变形。

分析总拥有成本 (TCO)

虽然使用定制激光切割服务的每小时成本可能略高于其他选项，但 TCO 将倾向于选择使用激光器，因为所获得的高精度消除了执行任何额外过程的需要，例如铣削和铰孔。此外，自动激光切割取得的出色成果使焊接操作更加轻松，检查时间更少，从而提高效率并节省隐性费用。

凭借设备的高技术能力，证明了使用多轴激光切割技术在经济性地制作精密零件方面的优势。 立即联系我们的激光切割专家，确保您的厚板零件具有卓越的边缘质量、DFM 优势并长期节省成本。

为什么等离子切割成本优化是大型结构部件的最佳策略？

在梁和底座等大型结构零件中，当精度比坚固性更重要时，等离子切割成本优化是迄今为止最有利的方法。本文探讨了仔细选择工艺和使用嵌套切割可以最大限度地减少浪费和降低每个零件的成本的方法。对切割工艺的讨论专门针对重工业市场，而不是工业激光切割的应用。

Plasma cutting cost optimization is a highly precise engineering solution for the issue faced by the customer when it comes to the management of large-budget projects. The matter of optimum material usage by means of nesting and fast plasma cutting makes the justification of the chosen technology quite precise from an engineering point of view, without any costly precision tube laser cutting.

How Do OEM Metal Cutting Services From LS Manufacturing Ensure 100 Percent Material Traceability?

For industries like aerospace and nuclear power, a lack of full material traceability is one of the main compliance and liability risks. This paper describes how we have set up an interlocked process chain for our OEM metal cutting services to ensure that there is full traceability from start to finish. Here are the concrete steps by which we translate a compliance issue into a distinct competitive advantage for us:

Verification at Point of Entry: Positive Material Identification (PMI)

All incoming materials must be tested for PMI using the Spectrometer system before acceptance. The test determines the alloy type and its chemical composition, compared to the mill certificate. It is the first digital proof in the life cycle of each component to ensure material integrity and lay the groundwork for precise part manufacturing.

In-Process Data Logging and Binding

The critical parameters of the process are automatically recorded during manufacturing. In case of multi-axis laser cutting for complex parts, the relevant information is collected through dynamic laser cutting systems, linking the batch numbers to the information on cutting power, speed, and gases used.

Comprehensive Certification and Documentation Delivery

The ultimate step in this process is the generation of an exhaustive Material Test Report 3.1b and FAI report that includes complete dimensional data. This document set is the very foundation of our quality assurance protocol and constitutes the official paperwork required for the audit process of the client. This is essential for the approval of mission-critical laser cutting for precision parts.

In terms of the traceability protocol employed in our company, the core issue that needs to be addressed is the fear of non-compliance audit due to a lack of manufacturing documentation. The problem is tackled by incorporating the real material information together with the manufacturing information into the documentation for each component made. This means that we will have sufficient documentation for the certification of each piece made by the certified laser cutting process.

Why Is Laser Cutting For Precision Parts The Key To Accelerating Your Product Time To Market?

It should also be noted that the time involved in carrying out the longest phase is that of iteration of the prototype component. Thus, laser cutting for precision parts without requiring any tooling is an absolute necessity in order to enable quicker iterations, which would ultimately lead to fast product development. Below are described some of the ways in which high precision laser cutting as well as engineering assistance can have a huge effect on development cycle times:

Eliminating Tooling with Digital Prototyping

• Rapid Turnaround:​ Use advanced laser cutting to create "soft tools" that allow development of digital prototypes in 48 hours.
• Client Benefit:​ Rapid prototyping allows tests to be carried out regarding fit, form, and function in less than one week before the end of the project.

Design for Manufacturing (DFM) to Ensure First-Pass Success

1. Proactive Intervention:​ Checking design features and suggesting changes such as replacing welding with direct laser切割。
2. Measurable Outcome:​ Such an improvement, coupled with laser-cutting precision, increases first-assembly success rate to 99.8% without any need for rework and downtime.

Integrated Service for Seamless Progression

• Unified Workflow:​ Providing an integrated service from CAD file all the way to final part manufacturing with processes such as cutting, bending, and finishing.
• Efficiency Driver: Such a holistic approach eliminates the communication issues associated with coordinating multiple contractors, which is one of the major sources of LS Manufacturing efficiency.

The issue of delays due to unavailability of prototyping and assembly processes is solved by tool-free manufacturing and proactive design for manufacturability. This integrated process of high-efficiency laser cutting guarantees that our design is transformed into a validated part seamlessly, thus becoming the ideal risk management strategy and first mover advantage.

Case Study: LS Manufacturing Aerospace Titanium Structural Joint Precision Custom Solution

This is an example of the innovative process solution that helped LS Manufacturing overcome the critical challenge faced while manufacturing an expensive aerospace component. We used our custom laser cutting technique to overcome the limitations of regular thermal cutting methods and transformed the production limitation into a production benchmark for quality:

客户挑战

One of the OEMs of international aircraft faced difficulties manufacturing custom Ti-6Al-4V reinforcements. The brackets were getting subjected to thermal oxidation and cracks up to 0.8 mm in depth using plasma cutting processes. Fatigue testing showed that such components could not function beyond 60% of their useful lifespan. This made it necessary to develop a high-stability laser cutting process.

LS 制造解决方案

The shift occurred towards the ultra-precise laser cutting technique utilizing a highly powerful laser accompanied by the highly purified argon gas as assist gas. The critical innovation involved in this approach was a special cryogenic cooling work table, which aimed to extract the heat from the part itself. Alongside a specialized DFM-oriented feed rate strategy, this controlled laser cutting technique helped to eliminate the Heat Affected Zone (HAZ) to below 0.05mm.

结果和价值

The re-engineered brackets successfully passed through 1,000,000 cycles of fatigue loading test without showing any signs of micrometrical cracks, thus verifying the calculated lifecycle of the parts. This successful outcome of the reliable laser cutting ensured that our customer could resume operations in their production facility two weeks ahead of the rescheduled date. Additionally, the high-quality cuts resulted in the absence of oxide layers and did not require any subsequent cleaning procedures, saving 15% off the cost per unit.

This project is an example of our unique ability at LS Manufacturing to utilize process knowledge in solving difficult manufacturing problems. By providing both the component and the technology, we were able to remove risks from a key path forward, reduce costs, and create a new performance standard. That's what technical authority looks like at LS Manufacturing.
