The configuration includes a drill name determining means and a life determining means for comparing the drill name and the number of times of use read out by the reading means with the specified drill name and the prescribed number of times of use. By identifying and managing the lifespan of drills, eliminating mistakes in using drills and using them at the end of their lifespan, Komei, who handles prints, can improve quality.

[Industrial application field]

The present invention relates to a drill type discrimination and life management method,
In particular, the present invention relates to a drill identification and lifespan management method that eliminates the use of incorrect drills or the use of drills at the end of their lifespan when using many types of drills.

During the drilling process for printed boards, dozens of holes with different diameters are created depending on the specifications. Further, since the drill has a limited working life, the drill must be replaced with a new one every specified number of uses. Therefore, a drilling machine that performs drilling on printed boards has a spare station that stores several dozen types of drills, each of which includes several dozen replacement drills.

The placement and storage of drills at this reserve station is all done manually, which results in human errors in placement and storage of the drills, and often results in defective drilling due to the wrong drill.

In addition, the lifespan of drills can be managed by checking the number of times each drill is used,
That is, the number of tips (the number of times the drill moves up and down) is calculated using a usage counter provided on the drill press, and the lifespan of the drill is artificially determined from the calculation result and replaced with a new drill.

Therefore, the arrangement of trills at the reserve station.

There is a need for a method that can prevent drilling defects by detecting human errors during storage before drilling, and that can automatically manage the lifespan of each drill.

When drilling holes in the printed board 1, several dozen types of holes with different diameters are machined depending on the specifications of the print Ft. In machining these holes, the NC drilling machine 2 takes out a drill corresponding to the hole to be machined from the drilling station 6, sets it on the chuck 3, and drills the hole in the printed board 1.

In addition, to manage the lifespan of the drill, the number of uses (number of hits) of the drill is measured using a use number calculator 4 provided on the NC drilling machine 2, and it is artificially confirmed that the measured value has reached the specified number of uses. When the drill reaches the end of its life, it is replaced with a new drill stored in the spare station 6.

[Problem that the invention seeks to solve]

In the above-mentioned method, the placement and storage of dozens of types of drills at the preliminary station 6 are all done manually, so it is possible that mistakes may occur in the placement and storage of drills, resulting in different types of drills. Drilling often results in defects.

Further, the lifespan of the drill is determined by manually monitoring the calculated value of the hit count calculator 4, which makes the work extremely complicated.

The present invention was created in view of these points, and is based on the NC
A method for determining whether the specified drill is set in each chuck of a drilling machine, and automatically knowing when each drill set in the chuck of an NC drilling machine has been used the specified number of times. The purpose is to provide a lifespan management method that can
