Abstract
The invention discloses a machining center Z-direction manual tool setting method. The machining center Z-direction manual tool setting method comprises the following steps of manually measuring the distance L1 from a tool nose of a simulation tool to one point in the upper surface of a workpiece through a special simulation tool, setting a Z value of a workpiece coordinate system to be 0, measuring the length L2 of the simulation tool and the tool length L3 required for machining workpieces through an external tool setting instrument, calculating the tool compensation according to the following formula and inputting the tool compensation into a machining center tool correction interface. The machining center Z-direction manual tool setting method has the advantages of enabling tool setting to be direct and convenient, reducing various auxiliary time, reducing repeat tool setting inconvenience caused by tool replacement, improving the tool setting accuracy and improving the workpiece machining quality and production efficiency.
Description
Technical field
The invention belongs to machining center operating technology field, be specifically related to the method for the manual tool setting of a kind of machining center Z direction.
Background technology
Along with scientific and technical development, processing center machine tool is widely used in various manufactures field, processing a workpiece needs much knives tool just can complete, often stay the different in size of outside during cutter clamping, and, some surface of the work profiles are complicated, or some cutter work in-processes can run into wearing and tearing, the phenomenons such as breaking, this has brought sizable trouble just to machine operation personnel when replacing cutter is determined relevant parameter, if method of operating is incorrect, not only can cause tool setting error, cause machining accuracy and workpiece quality to decline, and can increase and affect production efficiency non-cutting time, serious meeting is scrapped workpiece, or the major accident such as occur colliding, so suitable presetting cutter method is most important for grasping.
When every XY coordinate figure cutter is constant, what change is Z coordinate figure, as long as the Z-direction that we find all cutters accurately when tool setting is so positioned on same surface of the work, now, Z-direction has a numerical value, is machine coordinate values, this numerical value is input to cutter bowl spares, or utilize basic-cutter and carry out correction-compensation value with the length difference of each cutter, then utilize Command of Cutter Length Compensation to call this value, can be using the same surface of all bit alignment workpiece as Z axis zero point.
Existing presetting cutter method has several, and a kind of is directly to the skill in using a kitchen knife in cookery, exactly each cutter is all contacted to workpiece surface, then machine coordinate values is directly inputted in cutter benefit, the Z value of workpiece coordinate system is 0, and this kind of method is convenient, fast, but for the workpiece that has complex surface, inapplicable; Second method is that to take the initial point of machine coordinates Z axis be 0, the cutter location of cutter is exactly tool length offset to the distance of cutter initial point, this method is when production lot workpiece, must workpiece be all limited to sustained height with fixing fixture, otherwise just must remeasure, reduce operating efficiency, both methods are tool setting fast and accurately all.
Summary of the invention
For addressing the above problem, the invention discloses the method for the manual tool setting of a kind of machining center Z direction, tool setting is more directly, conveniently, various non-cutting times have been reduced, also reduced and changed the cutter inconvenience of tool setting again, improved tool setting precision, improved workpiece crudy and production efficiency.
For achieving the above object, technical scheme of the present invention is as follows:
The method of the manual tool setting of machining center Z direction, is characterized in that: comprise the following steps:
(1) Z axis meeting initial point, packs special emulation cutter in machining center spindle taper hole into, with 200 revs/min of speed forwards;
(2) shake electronic hand wheel, the point of a knife of manual measurement emulation cutter is to any distance L 1 of workpiece surface;
(3) the Z value of workpiece coordinate system is made as to 0, the point of a knife of the emulation cutter in step (2) is the cutter benefit-L1 of emulation cutter to the distance of workpiece surface;
(4) emulation cutter is unloaded and pack on the outer tool setting gauge of machine, measure the length L 2 of emulation cutter;
(5) outside machine, on tool setting gauge, measure the first cutter length L 3 that processing work needs;
(6) cutter of first cutter is mended and is :-L1+(L3-L2);
(7) by that analogy, the cutter that calculates other cutters of processing work needs is mended, and the cutter of all cutters is mended in the cutter compensation value that is input to the corresponding sequence number of Cutters In Mc revisal interface phase.
As a modification of the present invention, the tail end of described emulation cutter is No. 4 taper shanks of Mohs, and centre is connecting axle, and the head of emulation cutter is drill bit type, and point of a knife outwardly.
As a modification of the present invention, described machining center is vertical machining centre.
The invention has the beneficial effects as follows:
The method of the manual tool setting of a kind of machining center Z direction of the present invention, tool setting more directly, conveniently, has reduced various non-cutting times, has also reduced and has changed the cutter inconvenience of tool setting again, has improved tool setting precision, has improved workpiece crudy and production efficiency.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Embodiment
As shown in the figure, the present embodiment is the method for telling about in the manual tool setting of vertical machining centre Z direction, comprises the following steps:
(1) Z axis returns initial point, special emulation cutter is packed in machining center spindle taper hole, with 200 revs/min of speed forwards;
(2) shake electronic hand wheel, the point of a knife of manual measurement emulation cutter is to any distance L 1 of workpiece surface;
(3) the Z value of workpiece coordinate system is made as to 0, the point of a knife of the emulation cutter in step (2) is the cutter benefit-L1 of emulation cutter to the distance of workpiece surface;
(4) emulation cutter is unloaded and pack on the outer tool setting gauge of machine, measure the length L 2 of emulation cutter;
(5) outside machine, on tool setting gauge, measure the first cutter length L 3 that processing work needs;
(6) cutter of first cutter is mended and is :-L1+(L3-L2);
(7) by that analogy, the cutter that calculates other cutters of processing work needs is mended, and the cutter of all cutters is mended in the cutter compensation value that is input to the corresponding sequence number of Cutters In Mc revisal interface phase.
This method is used G43 command of length compensation, in fact still, measure the cutter head of cutter to the distance between surface of the work, only, it does not need to measure only needs to calculate, but do like this service time that does not take lathe, can within nonproductive time, carry out, tool setting more directly, conveniently, has reduced various non-cutting times, while also having reduced replacing cutter, again the inconvenience of tool setting, has improved tool setting precision, has improved workpiece crudy and production efficiency.
