In the actual production of milling processing, including machine tool parameters, workpiece clamping, tool selection and other application skills, the editor found 17 key points of milling processing to everyone, in the hope of being useful to everyone.
1. Power capacity Check the power capacity and rigidity of the machine tool to ensure that the machine tool can use the required cutter diameter.
2. Workpiece clamping conditions and considerations on workpiece stability.
3. Keep the tool overhang on the spindle as short as possible during overhang machining.
4. Choose the correct cutter pitch. Use the correct cutter pitch suitable for the process to ensure that there are not too many blades involved in the cut, otherwise it will cause vibration.
5. Cutting engagement When milling narrow workpieces or spaces, make sure there is sufficient blade engagement.
6. Insert the geometry selection. Where possible, use indexable inserts with positive cutting angles to ensure smooth cutting action and minimal power consumption.
7. Use the correct feed Make sure you have the correct feed for the insert you are using by using the maximum recommended chip thickness to achieve the correct cutting action.
8. Use milling in the direction of cutting as much as possible.
9. Part Considerations Part material and configuration, as well as quality requirements of the surface to be machined.
10. Insert material selection: Select geometry and material based on workpiece material type and application type.
11. Vibration Damped Cutters For longer overhangs exceeding 4 times the tool diameter, the tendency for vibration will become more evident. Using vibration-damped cutters can significantly increase productivity.
12. Angle of attack Select the most appropriate angle of attack.
13. Cutter Diameter Select the correct diameter based on the width of the workpiece.
14. Position the cutter correctly.
15. Entry and exit of the cutter It can be seen that thanks to the entry of the arc, the thickness of the chips during retraction is always zero, thus allowing higher feeds and a longer life of the cutter. ‘tool.
16. Coolant Use coolant only when deemed necessary. Milling generally works best without using coolant.
17. Follow tool maintenance recommendations and monitor tool wear.
