Claims: What is claimed is:

1. In a building block system including a fixture block serving as a manufacturing accessory, particularly for the machining of metal workpieces and the like, adapted to be combined with further correspondingly designed accessories with the aid of which workpieces to be machined can be brought into proper position or orientation for the particular machining operation, such as planing, milling, drilling, honing, grinding, and the like, and maintained in such proper position or orientation during at least one working cycle, the improvement comprising a basic fixture block formed as an L-shape body, having its shape derived from the geometrical form of a rectangular parallepiped with all intersecting surfaces being mutually perpendicular to each other, having a pair of mutually perpendicular legs each having relatively wider inner and outer surfaces joined to each other by relatively narrow side surfaces, with the length and width of the relatively wider outer surface of each leg being equal to each other and to the length and width, respectively, of the relatively wider outer surface of the other leg, and the thickness, across the relatively narrow surfaces, of each leg being equal to one-half such length or width; the inner, outer and side surfaces of said legs forming contact surfaces and being formed with aligned rows of coplanar projecting areas separated by machined rows of coplanar recessed areas; all the surfaces of said block being formed with a plurality of tapped bores and with smooth untapped bores of different diameters, which at least partially intersect each other within the block.

2. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 1, in which said tapped bores are provided in both the recessed areas and the projecting areas of all surfaces of the block, the projecting areas of the block surfaces being those which have not been machined during machining of the recessed areas.

3. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 1, in which said intersecting bores are through bores.

4. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 3, in which certain of said through bores extend between recessed areas of the surfaces of said body.

5. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 3, in which said through bores include at least one large diameter through bore extending through each leg, perpendicularly to the inner and outer surfaces thereof, and opening through one of the respective projecting areas.

6. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 1, in which said tapped bores serve receiving threaded elements for securing manufacturing accessories, designed in correspondence with the design of said block, to said fixture block.

7. In a fixture block serving as a manufacturing accessory, the improvement claimed in claim 3, in which said through bores serve for mounting therein conformingly designed auxiliary means for effecting the mechanical, hydraulic, pneumatic and electromagnetic clamping of workpieces to be machined.
