Treatment of line cut taper and example of process designing technology apply

Liu Ying closes crane of king of afterwards sharp edge

Treatment of machine tool of cut of numerical control line solved a lot of traditions to machine the difficult problem that solves hard, the product treatment that reachs taper cut in acute angle, small R especially has an advantage more in the process, apply extensively already at the industrial domain such as mechanical mould, aviation, spaceflight. Punch-die unplugs the precision of modular face is having main effect to a model of the mould and service life, because of some, it is important to unplug modular pyramid spends treatment blame to be.

One, the treatment point of great deep work and taper cut

Great deep work and the key that taper product is machined is line cut all the time machine an object, also be one of difficulty, the perpendicular precision that improves great deep work reachs treatment efficiency, it is one of objectives that line cut treatment pursues all the time. The sunken model look that if the graph is shown 1 times,cut of great deep work often presents and vaulted. Because machine the resistor of fluid to had compared the tension of silk of low, cut,the account that produces form of vaulted or sunken model is commonly too small, guide the distance between the head passes to wait for a reason to be caused integratedly greatly. The circumstance of sunken to appearing form, can pass the average treatment voltage when reducing cutting 2 times (servo is fiducial voltage) will solve, and vaulted to appearing circumstance, want to heighten the average treatment tension when cutting 2 times.

1.The treatment when great deep work should order cut

When processing great deep work, can raise the verticality of great deep work and cut precision through the following method.

(The pulling force that 1) increases cut silk, reduce shower nozzle to guide the distance between the head;
(2) uses the cut silk with thicker diameter to undertake machining, increase treatment number;
(3) uses appropriative nozzle to improve the cooling result of cutting fluid.

2.The treatment of taper cut wants a place

To taper cut, its dimension often is controlled hard, and cut efficiency and compare without taper cut photograph a lot of lower, it is especially below the case with very big taper, the difference is bigger. The environment that this basically is fluid of difficulty of bits of the platoon when be being machined as a result of taper, cutting is paid no attention to think what the reason that waits for many sided causes the parameter that reach report is unreasonable. The author is below from inside practice, the particular case when be aimed at taper cut sums up the point of a few treatment that give.

(Because 1) discharges bits difficulty when taper cut, seal wire model guides the cut silk of the head pulls motive force bigger, easy fracture of wire, because this must reduce treatment energy, increase discharge time interval, increase the average tension in machining a process;
