How to use a coordinate measuring machine for reverse engineering? Published: 2019-11-20 Source: https://www.microaccuracy.com/ As a new industrial design and manufacturing concept, reverse engineering uses certain measurement methods to measure objects or models, and perform measurements based on measurement data. In model reconstruction design, the coordinate measuring machine is an important device for precise measurement. How to use the coordinate measuring machine for reverse engineering? Reverse engineering is currently being gradually applied to various industries. It first designs a model for the product with a novel appearance and meets the space requirements, then conducts actual measurement on the existing product model, and then uses a three-dimensional coordinate measuring machine to obtain the three-dimensional shape data information of the object, and then Carry out data reconstruction and establish a CAD data model. Designers can carry out innovative designs on the CAD model to process products or molds, and finally finalize the product through experimental verification. The role played by the coordinate measuring machine in this process can be divided into four stages: the digitization of the original part: a measuring device such as a coordinate measuring machine or a laser scanner is usually used to obtain the three-dimensional coordinate value of the original surface point of the part. Extract the geometric features of the original part: segment it according to the geometric properties of the CMM measurement data, and use the method of geometric feature matching and recognition to obtain the design and processing features of the original part. Reconstruction of the original CAD model of the part: Fit the divided three-dimensional data in the CAD system to fit the surface model, and obtain the CAD model of the original surface of the part through the intersection and splicing of the surface pieces. Inspection and correction of the reconstructed CAD model: The method of re-measurement and processing of samples according to the obtained CAD model is used to test whether the reconstructed CAD model meets the requirements of accuracy or other test performance indicators. Repeat the above process for those who do not meet the requirements until it reaches Reverse engineering design requirements of parts. The coordinate measuring machine is an important equipment indispensable in reverse engineering. It mainly plays the role of accurate data measurement. At present, Miaoji Technology can provide a variety of different types of coordinate measuring machines and one-button measuring equipment. Customers provide strong and continuous technical support and value-added services to allow measurement equipment to exert greater benefits.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
