Detailed explanation of the use parameters of solid carbide spiral milling cutters
2025-08-28
Cutting parameters are crucial in metalworking, directly impacting machining efficiency, quality, and tool life. The following are some common cutting parameters and their applications in different material types.
I. Cutting Parameters
1. Linear Speed (Vc): Indicates the distance the tool travels in the cutting direction per unit time, typically measured in meters per minute.
2. Feed Per Tooth (fz): Indicates the linear distance each cutting edge travels during cutting, typically measured in millimeters per tooth.
3. Axial Depth of Cut (ap): Indicates the depth of cut in the axial direction of the workpiece, typically measured in millimeters.
4. Radial Depth of Cut (ae): Indicates the depth of cut in the radial direction of the workpiece, typically measured in millimeters.
II. Cutting Parameters for Different Material Types
1. Mild Steel/Alloy Steel:
Linear Speed Range: 80-150 m/min
Feed Per Tooth Range: 0.08-0.15 mm/z
Axial Depth of Cut: Typically no more than 30% of the workpiece diameter (i.e., ≤0.3D)
Radial Depth of Cut: Same as above
Application: Suitable for roughing.
2. Stainless Steel:
Linear Speed Range: 30-60 m/min (Stainless steel is harder and more prone to heat generation, so the line speed is lower.)
Feed Per Tooth Range: 0.05-0.10 mm/z
Axial and radial Depths of Cut are relatively small, typically no more than 20% of the workpiece diameter (i.e., ≤0.2D and ≤0.3D).
Application: Suitable for finishing stainless steel, especially when preventing chatter.
3. Cast Iron:
Linear Speed Range: 70-120 m/min
Feed Per Tooth Range: 0.10-0.20 mm/z
Axial Depth of Cut: Adjustable based on machining needs, but ensure the machine capacity is maintained.
Applications: Suitable for rough and finish machining of cast iron.
Please note that the above values are for reference only and should be adjusted in practice based on specific equipment, tooling, workpiece material, and other factors. Ensure safe operation to prevent accidents. It is recommended that metalworking operations be performed under the guidance of a qualified professional.
