The invention primarily relates to a system (10) for detecting a total or partial obstruction of at least one internal fluid pipe (11) of a tool (12), characterised in that said system (10) comprises: a pneumatic system (13) that is intended to be connected upstream of said internal pipe (11) of said tool (12), a pressure source (16) that is connected to said pneumatic system (13) by means of a solenoid valve (17), and a control unit (22) that is configured to open said solenoid valve (17) so as to pressurise said pneumatic system (13), and then to close said solenoid valve (17) so as to let said pneumatic system (13) be emptied freely by means of said internal pipe (11), and to detect an obstruction state of said internal pipe (11) depending on an analysis over time of a change in the pressure in said pneumatic system (13).

A machining center having at least one door to control access to an enclosure thereof, where access through the door is provided by an unlocked latch, and the latch is unlocked based on wirelessly communicated signals relaying information about at least one operating condition of a fluid driven cutting tool spindle in use within the machining center.

A lens edging system of the present invention includes: an edger configured to perform edging of a spectacle lens using an edging tool; a shape measurement device configured to measure an edging shape of a circumferential edge of the spectacle lens after edging by the edger; a memory part configured to store information regarding a reference shape of the edging tool used by the edger; a shape comparing and judging part configured to compare a measurement result obtained by the shape measurement device and a reference shape of the edging tool specified from the information stored in the memory part, and judge necessity/non-necessity for exchanging the edging tool based on a comparison result; and an information output part configured to output information regarding necessity for exchange when the shape comparing and judging part so judges.

A processing system having a function for appropriately maintaining processing accuracy, without depending on a degree of abrasion of a tool. An unused tool used in a machine tool is captured by using a camera mounted on a robot, so as to obtain a reference image of the tool. Next, an image of the tool is captured after a predetermined number of processing operations carried out. An average amount of tool abrasion per one processing operation is calculated based on the two images, so as to estimate a current amount of tool abrasion. Based on the estimation result and a previously input limit amount of abrasion, the number of remaining possible processing operations of the tool is calculated and output.

In a tool exchanger apparatus of a machine tool including a turret which turns around an axis inclining with respect to a vertical direction and which conveys tools, forces applied to tool gripping portions are calculated from a resultant force of a centrifugal force, gravity and an inertial force applied to each of the tools, using a weight and a position of each of the tools and a turning speed and a turning acceleration of the turret for each of turning phases when the turret turns, and the turning speed and the turning acceleration of the turret are determined for each of the turning phases.
