Tool geometry directly dictates chip flow, cutting forces, and the thermal load experienced by the cutting edge.
Three primary forces act on a cutting tool during operation:
A larger nose radius improves surface finish and strengthens the tool tip, but increases radial cutting forces, which can induce vibration in thin parts. Section 4: Primary Metal Cutting Processes modern metal cutting a practical handbook free
Modern methods focus on high-speed removal and precision finishes.
The tool rotates with the feed direction. It produces a thick-to-thin chip, which reduces heat and improves surface finish. This is the preferred method for modern rigid CNC machinery. Tool geometry directly dictates chip flow, cutting forces,
With these details, I can provide custom cutting parameters and targeted troubleshooting steps. Share public link
