Abstract
To insure that cylindrical bores, and particularly blind bores (8) in a workpiece (9) are truly cylindrical, or of predetermined geometry even in the region adjacent the bottom of the blind bores, a honing blade carrier (4) has a set of long honing blades (5, 5a) of about the length of the bore and a set of short honing blades (6, 6a) located adjacent the bottom of the bore on the tool, with the short honing blades being independently adjustable; sensing elements (25, 26, 27) are integrated with the tool carrier (4) to sense the dimension of the bore at various levels or planes (A, B, C), the output signal from the plane (C) of the bottom of the bore being processed in a controlled channel (32) to adjust, individually, the honing pressure exerted by the short blades, in relation to tool feed, and hone the bottom of the bore to the appropriate size, as determined, for example, by a sample standard (28) having a sensing plane (D) which can be sensed by the same sensing elements as those which sense the bore, upon withdrawal of the honing tool carrier through the standard (28).
