With a CNC milling machine where the spindle speed and Z travel can be synchronised (a G33 move for example) it it possible to use an automatic boring head to bore tapered holes. The radius change per rev is fixed (or has only a few options, depending on the head) so you just need to choose the Z feed rate to give the required angle. ...

A CNC mill calculates speeds and feeds or SFM based on the information the user enters. The type of CNC mill, the type of machine controller, and the age of the machine will affect the amount of information that can be input directly into the machine.

where N is the number of flutes of the end mill and Rpm is the rotational speed of the spindle. Let's illustrate this concept and imagine you want to cut plywood with a 6mm 2flutes end mill. In our case, the recommended chip load for plywood is around 0,17mm/tooth (cf. the Advanced chip load table at the end of this article). Let's define an arbitrary feedrate of 1 700 mm/min.
