* Ramping: Instead of plunging, the end mill can be angled to gradually enter the material, reducing the cutting load202142—Current strategy is topeck drill a number of 6.5mm holes to depthand the run the slot with a 2 flute carbide end mill at 80% F and S (12000rpm 

Cutting Parameters:

* Spindle Speed (RPM): For aluminum, higher spindle speeds are generally favoredDeep Slot Milling in Aluminium - Optimum Cutter Diameter A common starting point for a two-flute end mill might be around 12,000 RPM, but this will vary based on the cutter diameter and materialSlotting - In the Loupe Machinist Blog

* Feed Rate (F): The feed rate determines how quickly the cutter advances through the material2025328—Slot cutting is a type of milling technique thatuses a rotating cutting toolto create channels, slots, or grooves in a workpiece. For a 12,000 RPM spindle speed, a feed rate of 80% of the recommended value is often a good starting pointSlotting - In the Loupe Machinist Blog This means if the recommendation is 1000 mm/minute, you might start with 800 mm/minute202142—Current strategy is topeck drill a number of 6.5mm holes to depthand the run the slot with a 2 flute carbide end mill at 80% F and S (12000rpm 

* Depth of Cut: This should be managed carefully to avoid overloading the cutter2023811—Slot milling, also called groove milling, is a machining process where arotating cutting tool is used to cut a slot in the workpiece. It's often better to take multiple shallower passes rather than one deep passWhat is Slot Milling Techniques, Tips, and Practices

* Coolant/Lubrication: Using a suitable coolant or lubricant is essential when machining aluminumSlotting - In the Loupe Machinist Blog It helps dissipate heat, lubricates the cutting zone, and flushes away chips, preventing them from welding to the cutter202142—Current strategy is topeck drill a number of 6.5mm holes to depthand the run the slot with a 2 flute carbide end mill at 80% F and S (12000rpm  Machining aluminum benefits greatly from proper lubrication2023811—Slot milling, also called groove milling, is a machining process where arotating cutting tool is used to cut a slot in the workpiece.
