三坐标测量仪对模具的重要性 The Importance of Coordinate Measuring Machines (CMMs) for Molds

​三坐标测量机就以其高精度高柔性以及优异的数字化能力，成为现代制造业尤其是模具工业设计、开发、加工制造和质量保证的重要手段。为您讲解一下三坐标测量机对于模具工业的两个重要作用。

With high precision, superior flexibility and outstanding digitalization capability, Coordinate Measuring Machines (CMMs) have become an indispensable tool for design, development, machining & fabrication and quality assurance in modern manufacturing industry, especially the die & mold industry. This article elaborates on two key functions of CMMs applied in the die & mold sector.

一、三坐标测量机能够为模具工业提供质量保证，是模具制造企业测量和检测。三坐标测量机在处理不同工作方面的灵活性以及自身的高精度，使其成为一个仲裁者。在为过程控制提供尺寸数据的同时，三坐标测量机可提供入厂产品检验、客户质量检测、量规检验、模具工件的检测等附加性能。高度柔性的三坐标测量机可以配置在车间环境，并直接参与到模具加工、装配、试模、修模的各个阶段，提供必要的检测反馈，减少返工的次数并缩短模具开发周期，从而降低模具的制造成本并将生产纳入控制。

I. CMMs Provide Quality Assurance for the Die & Mold Industry and Serve as core inspection equipment for mold manufacturers

Boasting exceptional operational flexibility across diversified tasks and ultra-high measurement accuracy, Coordinate Measuring Machines (CMMs) act as metrology arbitrators. While supplying dimensional data for process control, CMMs deliver supplementary inspection functions including incoming material inspection, customer-oriented quality verification, gauge calibration, and dimensional testing of mold components.

Highly flexible CMM units can be deployed directly on the production shop floor to participate in all phases of mold production: machining, assembly, mold trial run and mold revision. By feeding back critical inspection data on-site, such equipment reduces rework frequency, shortens mold development lead time, cuts down mold fabrication costs and enables effective production process control.

二、三坐标测量机具备强大的逆向工程能力，是一个理想的数字化工具。通过三坐标测量机测头和不同结构形式的三坐标测量机的组合，能够快速的获取工件表面的三维数据和几何特征，这对于模具的设计、样品的复制、损坏模具的修复特别有用。此外，三坐标测量机的接触式扫描测头，利用测量软件提供的强大的扫描功能，能够完成自由曲面形状特征的复杂工件CAD模型的复制。无需经过任何转换，可以被各种CAD软件直接识别和编程，从而大大提高了模具设计的效率。

II. CMMs Feature Powerful Reverse Engineering Capabilities and Serve as Ideal Digitalization Tools

Combining CMM probing systems with various structural configurations of coordinate measuring machines enables rapid acquisition of 3D surface data and geometric features of workpieces, which is particularly beneficial for mold design, sample replication and repairing damaged molds.

Furthermore, equipped with contact scanning probes and empowered by robust scanning functions of metrology software, CMMs are capable of replicating CAD models for complex parts featuring free-form surfaces. The acquired measurement data can be directly recognized and programmed by diverse CAD software without intermediate format conversion, substantially improving the efficiency of mold design.

具体来说，在模具制造企业中应用三坐标测量机完成设计和检测任务时，要密切关注测量基准的选择、测头的标定和选择、测点数及测量位置的规划、坐标系的建立、环境的影响等多方面的因素。这当中的每一个因素，都足以影响测量结果的效率。

Specifically, when CMMs are deployed at mold manufacturers to fulfill design verification and inspection tasks, close attention shall be paid to multiple influential factors including selection of measurement datums, probe qualification and selection, planning of sampling points and measuring positions, establishment of coordinate systems, as well as ambient environmental impacts. Each of these parameters can substantially affect measurement accuracy and testing efficiency.

 三坐标测量机在模具生产中的应用已经是迫不及待了，有些模具的设计就需要用到三坐标测量机。可以很大程度上提高模具的设计效率，精度也会得到大大的提升。

The application of CMMs in mold production has become imperative, and CMMs are essential for the design of certain molds. Their deployment can significantly raise mold design efficiency and greatly improve dimensional precision.
