ABSTRACT:
A component placement machine comprising an X-Y table, at least two pick-up tools movable between an up-position and a down position is set up to allow for movement of each tool in a horizontal plane in moving between its down position and its up position. A test piece is removably mounted in a pocket on the X-Y table so that it is accurately reproducibly mounted. The test piece is picked-up by a pick-up tool in its down position and a detection device detects the actual position of the piece on the tool in its up position. This is repeated for all the tools so that, when the X-Y table drive is used to compensate for variations in component position on a tool, as detected by the detection device, account can be taken of said movement in a horizontal plane.
