Abstract
A method for determining efficiency of a drilling process comprising the steps of: transferring energy via a tool member to the material in which drilling is to be performed by means of a drilling configuration; detecting waves which are propagating in said tool member of said drilling configuration during drilling as a result of energy provision; detecting said waves by means of at least two sensor means arranged on mutually opposite sides of said tool member adjacent to, on a certain distance from, said tool member, which sensor means are based on inductive and/or capacitive detection of said waves in said tool member; and based on results of said detection, determining said efficiency of said drilling process.
