The invention relates to a machine tool industry, and can be used in CNC machining machines equipped with a tool shop, and is an improvement to the basic invention in accordance with the authors. No. 1065091.

The purpose of the invention is to expand the functionality when using the system on CNC machines equipped with a tool magazine.

FIG. 1 shows a single-spindle milling machine with a tool magazine and fixture; in fig. 2 is a tool block of a boring machine installed in an intermediate seat of the tool.

The automatic tool setting system on CNC machines equipped with a tool magazine (control circuit not shown) contains a frame 1 on which a table 2 is installed, having the ability to move along the Y coordinate. In the spindle head 3 a spindle 4 is installed. An intermediate slot 5 of tools located on the device 6, dimensionally connected with the bed 1. Above the intermediate nest 5 along the coordinate axis 1Y on the folding bracket 7 is installed a tool position correction device 8, which is also uniformly connected with tank and intermediate slot 5. In the tool magazine 9, as in intermediate slot 5 and spindle 4, there are blocks with tools. On the table 2, the workpiece 10 is fixed, and the point 11 is the common starting point of the program.

FIG. 2 shows an intermediate socket 5 of the device 6 mounted on a CNC boring machine. This device 6 contains a block 12 of boring tools mounted on axis 2Y, in slot 13 of which cutter 14 is mounted along axis R. 14 to the body of the block 12 tools. The tool position correction device 18 is installed along the coordinate axis R. Point 19 is the starting point of the program at coordinate R. In the case of device 6, there are actuators 20 and 21, which are equipped with a 3333

The installation of block 12 iruehmeiton in 1 re- method 6 is joined to device 15 and 16.

The tool setting by the automatic tool setting on a single-spindle CNC milling machine, equipped with a tool magazine, is done as follows.

At the command of the CNC Unit, the capture manipulator (not shown) removes the block with the first tool from the tool magazine 9 and sets it to

15, an intermediate pocket 5 of the tool 6, where the tool position correction device 8 enters into the memory device (RAM) information on the value Y, for the first tool.

Q With the next command, the CNC Unit transfers the block with the first tool from the intermediate slot 5 to the spindle 4, and slot 5 sets the block with the second tool, where

25 simultaneously with the machining of the workpiece 10 by the first tool, the tool position correction device 8 enters into the memory information about the value Y, for the second tool. In the beginning of machining the workpiece 10, the first tool table 2, displaced from its zero position along the Y coordinate, processes information on the value of Y for the first tool, with the result that the tool tip gets to a point which, with a constructively specified distance Y programs for all instruments for any flight about

Setting the tool in the fixture is as follows.

At the command of the CNC Unit, the gripper of the manipulator (not shown) installs the block 12 with the boring cutter 14 (Fig. 2) into the intermediate slot, orienting the cutter 14 along the R axis. In this case, the devices 15 and 16 are joined with their actuators 20 and 21. Distance R1 const, the distance R2 is a random value, the distance (R2 + LK) is specified by the program. At the command of the CNC Unit, the tool position correction unit 18 measures the value (& R + + R3), after which the TNC calculates the value R2 RI - (& R + R3) T.,.

The next action UCHPU vuchisl -. em value + AR) -CR l- (dR + R3) J,

The clamping device 16 uses its drive 21 to release the shoe 17, and the device 15, also with the help of its drive 20, moves the cutter 14 by the value of LK, after which the shoe 17 is commanded by the CNC again to fix the cutter 14.
