An angular positioning device applicable on machines (1) for machining panels (2) made of wood or similar materials comprises: a worktable (3) consisting of a fixed supporting portion (3a) and a portion (3b) which is mobile, in both directions, along a direction of feed (A); a machining tool (4) attached to the fixed portion (3a) and positioned parallel with the direction of feed (A); a reference and rule fence (5) for the panel, which pivots at (X), on the mobile portion (3b) and whose angle can be adjusted relative to the direction of feed (A) to define angled cuts on the panel (2); the fence (5) has panel (2) reference - stop parts (6) designed to allow the display of an operating reference dimension (Q) on the fence (5) and having a cutting zero point (PZ) belonging to the tool (4) cutting plane (4a); the device comprises means (8) for adjusting the linear position of the fence (5) relative to the cutting plane (4a), said means operating between the fence (5) and the pivot point (X), designed to allow the fence (5) to be adjusted parallel with itself, according to the angular position reached, so as to keep the measurement defined between the reference - stop parts (6) and the zero point (PZ) constant at any angle value ( alpha ). <IMAGE>
