Milling Methods and Their Characteristics

The video tutorial explores two milling methods for roughing with solid carbide end mills: conventional slot milling and high-feed side milling. It discusses their working principles, advantages, and disadvantages. Conventional slot milling involves maximum arc engagement and is suitable for stable conditions but generates high heat and requires more power. High-feed side milling, on the other hand, uses a continuous spiral path with low radial engagement, offering better tool life and productivity, especially in hard materials. The video concludes that high-feed side milling is preferred for confined cavities, deep slots, and heat-resistant alloys.
