Detoureuse copieuse qui comprend un gabarit (18) ayant une surface portant des indices tels que des lettres ou des chiffres inscrits ou autrement formes. Il est aussi prevu un support de gabarit tel qu'une table (10) et une piece d'accouplement (35) reliant la surface du gabarit a la surface de la piece de travail (36). La piece d'accouplement (35) comprend des moyens d'evidage (41/50) pour usiner la surface de la piece de travail (36) ainsi que des moyens d'engagement (38/38a) pour les indices de la surface du gabarit. La piece d'accouplement (35) est aussi munie de moyens (78/79/80) par lesquels elle est rattachee de maniere pivotante a la surface de gabarit afin que la piece d'accouplement (35) puisse pivoter par rapport a celle-ci. Un cadre de montage (39/40) pour la piece d'accouplement (35) est mobile vers le haut ou vers le bas par rapport a la piece d'accouplement (35) afin de traiter la surface de la piece de travail a differentes hauteurs par rapport a la surface du gabarit.

The template (2) supports and guides a cutting tool (82) used to cut joint members in two workpieces (62,64) and comprises a support surface (20) and at least one set of guides (22-26) formed on the support surface (20) for guiding the cutting tool (82). The support surface (20) is movable with respect to the workpiece positioning member (14) at a predetermined distance between a first position to cut joint members in one workpiece (62) and a second position to cut complementary joint members in another workpiece (64). This arrangement permits accurate routing of rounded or square finger joints or other types of uniform, spaced joints as determined by the template (2) being used. Moving the template (2) with respect to fixed workpiece positioning members (14) means that no adjustment of the positioning members (14) or workpieces (62,64) is necessary between cutting of complementary joint members on separate workpieces (62,64) which tends to result in more accurate cutting of the joints. In addition, there is disclosed an adjustable guidebush assembly (85) for use with the template (2) to vary the tightness of fit of the joint members.

A rotor mountable fixture (30) is used for guiding a cutting tool (62) powered by a hand held air motor to machine a gas turbine engine rotor (10) without removing the rotor from its mountings in the engine. The fixture includes a root (45) having the same contour as a blade root slot of a rotor (10), a base having a platform attached to the root, and a machining guide in the form of a bushing (50) restrained in a guide slot (38) operable to receive and guide a hand held air motor powered cutting tool (62) for machining the rotor. This provides an accurate means to machine a gas turbine engine rotor without removing the rotor from its mounting. The hand held air motor may be used to power a machining tool to cut a blade damper pocket (20) in the dovetail slot of a pressure compressor rotor.

This edge working apparatus is provided with: an X direction drive device, which reciprocates in the X direction; a cutter supporting member, which is supported by means of the X direction drive device and is capable of traveling in the Y direction, and which supports a cutter member that extends in the Z direction perpendicular to the XY plane; a guide member, which has a shape that corresponds to a planned working shape when viewed from the Z direction, and which guides the cutter supporting member such that the cutter member moves along the planned working shape; and a Y direction position changing mechanism that changes, in the Y direction, the position of the cutter supporting member with respect to the material to be worked. The Y direction position changing mechanism changes the position of the cutter supporting member such that the cutter member returns further inside compared with the time when the cutter member advances.
