Introduction: Tapping on CNC Machines with G84. G84 g code is commonly used to program tapping. Tapping is a common operation used to thread holes on CNC Machines. For more on the Feeds and Speeds as well as the different kinds of taps and tap holders, see our companion Tapping Feeds and Speeds article. In this article, we'll be looking at two ways of programming tapping on a CNC

The Milling Process – Definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters

D = Tool Diameter in inches. Milling Feed. The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter. On the milling machines we have here at LBCC, the feed is independent of the spindle speed. This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters. The feed rate used on a milling machine depends

This formula can be used to figure out the feed rate that the cutter travels into or around the work. This would apply to cutters on a milling machine, drill press and a number of other machine tools. This is not to be used on the lathe for turning operations, as the feed rate on a lathe is given as feed per revolution.

The RPM formula for tapping is no different from the other formula we have been using, but the consideration mentioned for tapping must be made before we actually do any power tapping. Until you know how the tap will operate under your conditions, start with 1/3 to 1/2 the calculated RPM and gradually increase the RPM to the capacity of the conditions.
