Embodiment 1

[0031] This embodiment generates a microprism numerical control file in which a triangular pyramid is a reflection unit.

[0032] Step 1: Input processing overview. Time: 2015.12.01; Ambient temperature: 20℃; Ambient humidity: 55%; Mold material: Aluminum; Accuracy requirement: 10μm; Error requirement: <1μm;

[0033] The second step: define the three corner directions of the microprism as 0°, 60°, and 120°, the angle between the reflection units in these three corner directions is 70.5°, and the height of the apex of the triangular pyramid to the bottom is 60 μm. Such as figure 2 The processing simulation diagram shown.

[0034] The third step: define the machine tool processing parameters, the cutting depth is 10μm, 30μm, 50μm, 60μm respectively. The number of arrays in each rotation direction is 21; the X, Y, and Z three-axis processing speeds are F600, F600, and F20, and the Z-axis retract distance is 0.5cm. Such as image 3 Machining simulation after the array shown....

Abstract

The invention discloses a micro-prism reflection die CAM system, and the system employs a nesting modularization design. The system comprises a parameter input module, a machining analysis module, and a result output module. The system can freely customize a die type, the shape of a die substrate, the geometric parameters of a prism, the machining mode of a machine tool, and the machining parameters of the machine tool, carries out analysis according to customization data, and provides a simulation result for display. The system carries out the comprehensive judgment of reasonability according to the above customized parameters, gives an optimal or the quickest machining mode, estimates the machining time, and simulates a final machining preview map. The final result can be exported as a numerical control file, and the numerical control file can be provided for a diamond lathe for machining a micro-prism original die. The system controls the precision error to be lower than nanoscale, and a super-precise diamond lathe reads a generated numerical control code and can machine a good-quality super-precise micro-prism reflection original die.

Description

technical field [0001] The invention belongs to the field of computer software and is used for a CAM system for manufacturing original molds of microprism reflective materials in ultra-precision processing. Background technique [0002] As a retroreflective material, microprisms can reflect incident light back to the light source. Due to its advantages of energy saving and environmental protection, it is widely used in traffic safety signs, engineering road signs, clothing and other fields. [0003] The retroreflection efficiency obtained by microprisms with different geometric structures of reflective units will be different. Common geometric structures of reflective units include V-shaped grooves, cube corners, and triangular pyramids. The reflective units are then arrayed and assembled to obtain microprisms. [0004] The original mold of the microprism is mainly made by ultra-precision machining equipment diamond lathe. The process of writing the CNC program of the lathe...
