CNC carving processing, CNC carving processing:
Only a reasonable selection of taps can ensure the smooth processing. 2. Thread milling method, N35 G0 X-2 tool yield, and (5) the processing efficiency is low. It is only applicable to single small batch, special pitch threads and the absence of corresponding tools.
From the perspective of geometry, the shape and geometric angle of the tool, especially the arc radius of the tool tip, the main deflection angle, the auxiliary deflection angle and the feed rate in the cutting parameters, have a great impact on the surface roughness, (2) physical factors, from the perspective of technology, have an impact on the surface roughness of hardware parts (L í ng), mainly related to cutting tools Factors related to workpiece material and NC machining conditions, etc.
Profiles can be divided into round steel, square steel, hexagonal steel, flat steel, angle steel, channel steel, I-beam and other profiles with special sections according to the cross-section shape (x í ng). Profiles can be divided into hot (R è) rolling and cold drawing. Hot rolled profiles have low precision, but the price is cheap. They are used for Roughcast of general parts. Cold drawn profiles have small size, high precision, easy to realize automatic feeding, but the price is high.
The positioning is accurate, and the influence of clamping error and positioning error on processing quality is reduced.
CNC carving processing:
According to the bearing capacity of the tool (J ù), adjust the cutting amount to give full play to the maximum efficiency of the machine tool. A: because different machine tools can recognize different address codes and NC program formats, so (Y ǐ) The correct post-processing format should be selected for the machine tool used to ensure that the compiled program can run. Due to the complexity of NC processing (such as different machine tools and different materials).
Once the goods (w ù) are overstocked, the depreciation range is large, and the customer has no use value after making mistakes, so they can only be returned or discarded. Maintenance: diesel (steam (Q ì)), oil and gear (CH ǐ) Wheel oil, engine oil filter, diesel filter (fuel filter), air filter, 1 The business models of accessories vary greatly with the use of cars, and the failure modes of cars and trucks lead to different sales of various accessories.
Among them, the accuracy of geometric shape (x í ng) includes roundness, straightness and flatness, and the accuracy of mutual position includes parallelism, perpendicularity and coaxiality. 2. Final heat treatment: its purpose is to improve the hardness and wear resistance of parts, including quenching, carburizing, nitriding and other processes, generally in semi finishing (G ō After ng, fine addition (Ji) ā) Before work, 2. Heat treatment in parts machining process: 1. Accuracy of machining: 1. Dimensional accuracy: mainly including trial cutting method, adjustment method, sizing method and automatic control method.
