Information about Machining of the Turning Part 1 Information about Machining of the Turning Part 1

Firstly, Cutting the amount of turning parts

1. Cutting speed VC Cutting speed has a complicated influence on surface roughness. Generally, there will be no debris tumor when cutting at low speed or at high speed, so the surface roughness value after processing is small. Higher cutting speed can also greatly improve productivity. For example, YT15 is used to cut 35 steel, and the critical cutting speed is v > 100m/min.

2. The surface roughness value will be reduced by appropriately reducing the feed amount f.

3. Generally speaking, the effect of cutting depth ap on the roughness of the machined surface is not obvious. However, when ap < 0.02~0.03mm, due to the influence of machining radius, extrusion, skidding and periodic cutting of the machined surface often occur, thus increasing the surface roughness. In order to reduce the surface roughness, the cutting depth should be selected according to the sharpness of cutting edge grinding.

Secondly, Machining tool parameters for turning parts

1. Increasing the edge Angle is favorable for reducing surface roughness. As the size of shielding s increases, the Angle before the actual work increases, and the cutting force F decreases significantly, thus reducing the vibration of the processing system and the roughness value of the processed surface.

2. The main Angle k cabinet, the secondary Angle k 'cabinet, the Angle k cabinet and the secondary Angle k 'cabinet, as well as the increase of the radius r rake, can reduce the cutting residual area and reduce the surface roughness.

3. The increase of surface profile o helps to reduce surface roughness. Large front - Angle cutting edge sharp, cutting layer plastic deformation and friction resistance small, cutting force and cutting heat reduction. However, the dimensions o cannot be too large, otherwise, the workpiece or cutter will be embedded, and the surface roughness value will be increased instead.

4. Improve the cutting edge grinding quality and reduce the roughness values of the front and rear surfaces of the cutter to be no larger than ra1.25mm.

5. Choose tool materials with low workpiece affinities, such as ceramic or titanium carbide for cutting carbon tool steel, and non-ferrous metal processing with diamond or ceramic tool.
