計測方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for measuring the position of a cutting edge of a tool in poling processing of an NC machine tool, such as a machining center, which has a cutting edge that is distant from the center of the spindle, or a tool whose cutting edge can be controlled by the U-axis using an NC axis. .

ものに特開昭６１−２４９２４９号がしられている。Conventional technology A tool with a cutting edge located away from the center of the spindle mounted on the spindle of a machining center or a tool with U-axis control may change slightly when the cutting edge is replaced, the tool holder is replaced, or the set position of the tool holder is shifted. Furthermore, due to wear caused by machining, etc., the position of the cutting edge from the center of the spindle gradually changes. In the past, it was difficult to measure the position of the cutting edge accurately on the machine. For this reason, the tool holder must be pulled out and the tool presetter outside the machine can be used to measure the axis diameter of the cutting edge, or the previously machined hole can be measured with a cylinder gauge, etc., to accurately determine the position of the cutting edge. Although the position was corrected, subtle errors were unavoidable when reinstalling the tool holder, and operator intervention was required. In order to eliminate this inconvenience, Japanese Patent Laid-Open No. 61-249249 discloses a tool that uses a touch sensor to measure the cutting edge.

すると複雑且高価な装置が必要になり好ましくない。Problems to be Solved by the Invention Touch sensors are normally installed on the table of the machine, and are often installed near the stroke ends of the machine in order to increase the machining range. For this reason, if the position of the cutting edge deviates significantly from the center of the spindle, there is an inconvenience that the stroke is insufficient and the cutting edge cannot come into contact with the touch sensor, making measurement impossible. If the touch sensor is configured to be auxiliary moved by a cylinder or the like to compensate for the lack of stroke, a complicated and expensive device will be required, which is not preferable.

The current value A of the contact position is stored, and the known distance between this current value A and the back surface of the cutting edge and the back surface of the cutting tool holder is
The distance C from the spindle center to the cutting edge is calculated by calculating A-B from T (! Move the spindle to a position where the cutting edge can come into contact with the touch sensor set up in the same manner, store its current value E, then store the current value F of the IJ axis, and then move the U axis to bring the cutting edge into contact with the touch sensor. Based on the current U-axis value G, the distance H from the cutting edge set at the F position to the spindle center is F-G1E.
It is obtained by the calculation of In addition, the current U-axis value J of the cutting edge is memorized, and the X (or ) axis, move the blade tip by the U-axis stroke in the direction in which it contacts the touch sensor, store the U-axis position K of that movement position, then move the blade tip in the X (or Y) axis to contact the touch sensor, and then Based on the current contact value, the distance MM between the cutting edge and the spindle center at the current U-axis position (a J) is determined by J - K.
It is obtained by calculating +I-.

As explained in No. 49, a cutting tool holder with a cutting edge is installed so that it can move in the direction perpendicular to the axis of the tool holder (U axis), and when the tool is mounted on the spindle, the drive installed on the spindle head The unit and the drive line are connected and the position is determined by NC. 1 is a spindle head whose position is controlled in the vertical (Y-axis) direction by a column (not shown); 2 is a spindle supported rotatably and indexably on the spindle head; 3 is stored in a magazine (not shown), and the spindle 2 is controlled by a tool changer A tool holder with a U axis is attached to the tool holder, and 4 is a tool holder that is movable in a direction perpendicular to the axis of the tool holder (U axis) and is connected to the NC drive system when the spindle is attached, allowing U axis control. The back surface 4a is finished parallel to the axis of the tool holder so that correct measured values can be obtained when it comes into contact with the touch sensor. 5 is a cutting blade attached to the tip of the cutting tool holder, and 6 is a touch sensor attached to the end of a table (not shown) so that the Y-axis direction is the operating direction. For the touch sensor 6 with T2, a straight test bar with an accurately measured diameter is attached to the main shaft 2, and the main shaft is moved downward in the Y-axis direction to make contact with the touch sensor. The Y-axis value obtained by subtracting 1/2 the diameter of the test bar from the current value is set as zero. Also, before storing the tool holder 3 in the magazine, use a presetter etc. to insert the tip of the cutting blade 5 and the back surface 4 of the tool holder 4.
The dimension between a and a is accurately measured and the value is stored in the NC device as a POST value.

According to the second aspect of the present invention, since each current value F, G, and E can be detected accurately, the position of the cutting edge can also be accurately measured. Furthermore, since the U-axis can measure the cutting edge which is largely deviated from the center of the spindle with respect to the tip sensor provided near the stroke end, it is easy to do so and does not increase costs. Regarding claim 3, similarly to claim 2, the current value J, ! - can be detected accurately, so the distance JM between the cutting edge and the center of the spindle can be accurately measured. In addition, the U-axis can be used easily and has the advantage of not increasing costs.

How to measure the position of the cutting edge.
