ABSTRACT:
A two axis tracer (10) includes a back plate (34) and a front plate assembly (49) which includes a single sensing member (24) at the top end of which is a mushroom-shaped cap portion (28). Mounted on back plate (34) is a slider assembly (38) which moves in one direction between the front and rear edges of the back plate (34). The front plate assembly (49) is mounted to the slider assembly (38). A first air cylinder (60) operating a lever arm (52) provides movement of the sensing member (24) in the other direction, which is perpendicular to the one direction. A second air cylinder (68) includes an extendable rod, the end of which is secured to the back plate (34), providing movement of the front plate assembly (49) by action of the slider assembly (38). The top and peripheral edge of the cap portion (28) contact surfaces of the part to be worked in the two directions.
