A surface-following type measuring machine is provided, which is capable of setting the measuring force to a proper value in an efficient and accurate manner without imposing a burden on the operator in exchanging at least one of the stylus and stylus holder according to the surface contour of an object to be measured. A main body is disposed for movement relative to an object to be measured. A measuring arm is supported by the main body for displacement relative thereto, and carries at one end thereof a stylus holder and a stylus in a manner permitting replacement of the stylus holder and the stylus. Displacement of the measuring arm is detected by a displacement detecting device. The measuring force acting upon the measuring arm is adjusted by a measuring force adjusting device. A memory stores a measuring force command value table having a plurality of command values of the measuring force corresponding respectively to combinations of plural kinds of the stylus holder and plural kinds of the stylus. A kind of the stylus holder and a kind of the stylus after replacement of at least one of the stylus holder and the stylus are designated by an input device. A controller reads a command value of the measuring force corresponding to a combination of the kind of the stylus holder and the kind of the stylus after replacement, which are designated, and delivers the read command value of the measuring force to the measuring force adjusting device.
