> Compensation algorithm for wire wire cutting
Time:2014-07-22 11:29Reading:time
In WEDM of compensation in the end how to count? Go that compensation algorithm of wire cut, is not difficult. It's easy to say, and it's not easy. The main is to see the performance of the machine and fixed, the energy is strong, add a little. Of course, the thread - cutting operator has been aware of it for a long time. Let's tell you a simple formula. The wire radius and discharge gap of the electrode wire = compensation value. If there is any amount of remainder, add a remainder. You can only use this formula first, the specific value can not be applied.
So let's discuss this specific algorithm.
In the preparation of WEDM program, calculating method of compensation amount for delta = wire radius + spark discharge gap + unilateral unilateral mold with the gap. The unilateral discharge gap on high-speed wire in wire cutting machine, usually for the value of mould 0.01mm. precision can meet the requirements for general but, for high precision mould, mechanically apply this method is insufficient. I think: according to the working experience in the preparation of high precision mould in wire cutting process, characteristic should be specific requirements for the mold and machine bed, are modified unilateral discharge gap and consider leaving a grinding amount to some extent, it can improve the mold machining accuracy and prolong the service life of the die.
Not all the machines are applicable, but the formula is the same. If the feeling is not sure, you can first use the waste to cut it and then adjust the data.
