Functional testing and working prototype

What is functional testing

Functional testing is the most basic working prototype built to validate a product design. In addition, it is an integral part of the assembly, testing, pilot and market research process that evaluates design, materials, strength, tolerances, assembly, working mechanism, manufacturability.

Manufactured using a variety of prototyping techniques and engineering-grade materials, functional testing is an alternative to finished products, allowing form, fit and function to be checked and tested under extreme operating conditions to improve designs.

Functional testing to simulate the final product

Create functional prototypes using production-grade materials that realistically simulate the mechanical function, chemical resistance, and thermal properties of the final product, showing its performance before production.

Create working prototypes of complex assemblies to check component shape and fit and ensure accuracy of pre-assembled parts; produce high-precision functional prototypes to measure, compare, or check for design errors, dimensional differences, and acceptable tolerances; support optics Develop functional optical prototypes for engineering testing, including light transmission and refractive index; add metal inserts, removable hinges, simulated overmolding processes, and more to functional prototype parts to simulate and validate finished product functionality.

Realistic functional prototypes help demonstrate the aesthetics and functionality of the final product. It provides design extensibility.

two-dimensional

High-precision granite base, column and beam to ensure high stability and precision, imported high-precision P-class linear guide, precision silent grinding screw, high precision, accurate positioning, automatic grab measurement

Select the corresponding drawing command, and the software intelligently and accurately draws the lines, circles and other primitives in the real-time image of the workpiece automatically. This drawing method is more accurate and faster than picking points with the naked eye, and avoids human errors.

height gauge

For online or batch inspection, it can measure height, depth, groove width, inner and outer diameter, hole center distance, shaft center distance, flatness, perpendicularity, etc.

Maximum perpendicularity error: 10μm Repeat accuracy: plane ±2μm, round hole ±3μm.

Measuring range: 415mm/16in Accuracy (full course): (2.5+4*L) μm (L in m)

three coordinates

The basic principle of the CMM is to put the measured part into its allowable measurement space, and accurately measure the value of the point on the surface of the measured part in the three coordinate positions in space.

The coordinate values of these points are processed by computer and fitted to form measurement elements, such as circles, spheres, cylinders, cones, curved surfaces, etc., and their shape, position tolerance and other geometric data are obtained through mathematical calculation.
