Ingersoll Cutting Tools Rigidity Analysis – #1

We at Cutting Tools Chicago aka General Cutting Tools along with Ingersoll Cutting Tools are going beyond the basics of finish milling to help you maximize the rigidity of your setup.  Maximizing rigidity will improve your end mill performance.


Among the many variables in milling, rigidity is one of the most important.  Quite often, it is the primary factor determining end mill performance. Due to their length-to-diameter ratio, end mills are the least rigid of all cutting tools.  Understanding rigidity and maximizing it can dramatically increase end milling productivity.
Some of the primary factors that affect rigidity are basic machine design, drive mechanism, bearing placement, spindle size, tool diameter and length, overhang, work piece, and fixturing. This discussion will focus on how end mill selection affects rigidity.

Rigidity: is affected by cutting force.  Cutting force produces deflection.


Force: is produced by a combination of cutting speed in Surface Feet per Minute (SFM) and power. Power is a function of the width and depth of cut, feed rate, and the material being cut. Soft materials require less power and hard materials require more.
