VERICUT software grooms in CNC Machining technology medium applied skill

4. Range of this software application is very wide, can use at effective treatment already, also can use at education to groom; Can use as independent software already, but as compositive as other CAM software. The article is its groom in the technology medium an application case. One, foreword is as machine tool of our country numerical control in industrial equipment have of rate rise, increase quickly to the demand of the operation personnel of numerical control machine tool, process designing personnel, how efficient, apace grooms qualified personnel of qualified CNC Machining technology, become the urgent matter of vocational training. The tradition grooms below mode, because price of numerical control machine tool is high, every groom the machine tool amount that the orgnaization has is limited, student can go up by turns only machine tool operation, efficiency is very low. And abecedarian is not familiar to the machine tool, easy generation machine tool collides, attaint machine. "The machine tool is little, the student that should groom is much, should achieve again groom the effect " , this contradiction makes development agrees with the CNC Machining of vocational training emulated a system to have pressing demand. 2, the CNC Machining that software of VERICUT software VERICUT can satisfy afore-mentioned requirement one kind namely emulates a system, it is developed by American CGTECH company, current latest edition is V5 originally.

4. VERICUT software emulates module by motion of NC program verification module, machine tool, optimize module of feature of method module, much axis module, advanced machine tool, substance to compare the module composition such as module and CAD/CAM interface, the CNC Machining process that can emulate machine tool of cut of numerical control lathe, milling machine, machining center, line and much axis machine tool to wait for a variety of treatment facilities. Can undertake NC program is optimized, shorten handling time, can have checked cut, owe cut, prevent a machine tool collision, exceed the mistake such as the journey. Have true three-dimensional substance to show the result, cutting model is measurable dimension, can save a model for examining, treatment of cutting of follow-up working procedure. VERICUT software applies extensively already at aviation, mould to make at present wait for an industry, its are the biggest the characteristic is to be able to emulate all sorts of CNC systems, can emulate a knife already file, can emulate the NC order that CAD/CAM postposition handles again. Buy a software to be equivalent to having much stage machine tool to be able to groom for process designing. VERICUT software is used at numerical control process designing to groom need module of program verification having NC and machine tool motion to emulate module only, if want those who have four-axle above machine tool to groom, still need to have much axis module. CGTECH company is issued technically education version is used for the school. Pro/ENGINEER software is in-house also and compositive have VERICUT module. 3, the emulation environment compose of CNC Machining machining complex is built should undertake NC program is emulated, need beforehand the emulation environment that compose builds whole machining complex, common procedure is as follows: (1) machining complex analysis, the semifinished product that system of coordinate of principle of motion of configuration of model of system of CNC of clear machine tool, machine tool and dimension, machine tool, machine tool and place use, cutting tool and clamping apparatus; (2) build model of machine tool geometry, build the hypostatic geometry model of component of machine tool motion and fixed component with three-dimensional CAD software, change into format of STL of VERICUT software practicable; (3) build cutting tool warehouse; (4) user file is built in VERICUT software, what the setting uses CNC system, build model of machine tool sports, namely component tree; (5) the geometrical model that adds each part, allow to locate truly; (6) parameter of setting machine tool; (7) save all files. Below it is with lathe of CJK6132 economy numerical control exemple undertake demonstrative. (1) the machine tool summarizes this lathe to be horizontal, smooth lathe bed, before the blade holder, 4 economy that are versed in a dynamoelectric tool carrier, pace takes electric machinery drive lathe. Place is FANUC with numerical control system, 0T, 2 linkage control two axes of X, Z, control fore-and-aft, transverse slide respectively. X axis component makes up 4 labour dynamoelectric square tool carrier (line of axis of rotation is perpendicular) , change a knife automatically. Main shaft frequency control, box of foot of two lathe bed, beds, main shaft is fixed component, clamping apparatus is 3 ungual chuck. Origin of machine tool coordinate is center of chuck right end panel, if department of machine tool coordinate pursues 1 show. The machine tool coordinate of lathe of economy of 1 CJK6132 of Normal Align=center> graph numerical control is (2) component classification depends on VERICUT software component to classify a principle, if component classification expresses 1 to show. Express component of 1 machine tool to classify (3) the 3D model that builds a part uses SolidWorks software model, build a model with athletic unit, can not join according to machine tool component structural literary composition is built. Base but 40 an organic whole build a model, also but each spare parts builds a model alone, assemble in VERICUT later. Main shaft box builds a model to take no account of in-house main transfer machinery, build appearance model only. Catenary of drive of axis of X, Z can simplify to be not built, also can build a model as fixed component. After building geometrical model, put additionally for STL format. (4) build component tree to set CONTROL to be first " FANUC, 0T " : Choose menu " OPEN of → of SETUP → CONTROL " , set in shooting a dialog box " SHORT CUT " for " CGTECH_LIBRARY " , choose " Fan0t.

Ctl " component tree is built after opening. Choose menu " MODEL → COMPonENT TREE " , play a component to cultivate a dialog box, click " Base → right key clicks → to choose APPEND → to choose ZLINEAR in cursor menu " , add Z axis, click " ZLINEAR → right key clicks → to choose APPEND → to choose XLINEAR in cursor menu " , add X axis. Same method, add other part, get if the graph is shown 2 times,the component is cultivated. The X axis square that fastens because of machine tool coordinate to point to handlers direction, be in when adding Z axis part, because acquiesce,the Xiang Weiyuan of X axis square of Z axis component leaves handlers way, because this should circle Z axis square to roll 180 ° , such, the X axis square of Z axis component points to handlers to ability. When adding 4 cutting tool, tool carrier reference point is center of tool carrier roll, a cutting tool circles Y axis to be the same as one direction to turn more 90 ° , change TOOL INDEX to be respectively from inside the COMPonENT ATTRIBUTES of every knife 1, 2, 3, 4, assign cutting tool number. The list that the graph gets 2 times is cultivated (5) cutting tool warehouse is built in TOOL MANAGER with commonly used outside knife of lathe tool of round thick lathe tool, essence of life, whorl, cut off grooving knife to be exemple, write down respectively for 1, 2, 3, 4 knives. Knife handle builds a model with SolidWorks software first, change its into STL format, facilitate when using, transfer into and adjust the position. Bit is installed in VERICUT, choose model of corresponding razor blade, input bit dimension. Every cutting tool cutting tool of setting of option of applicable GAGE OFFSET is opposite with tool carrier center slant buy, the distance that decides point of a knife chooses tool carrier center (DX, DY, DZ) , should wait with workpiece axes because of point of a knife tall, criterion DY must is 0. (6) add model of machine tool geometry to add share of roll of 4 workpiece, chuck, main shaft, cutting tool, tool carrier first, other press again cooperate a relation to join. When adding STL model, should notice to choose model TYPE to be MODEL FILES type, find document of corresponding STL format by BROWSE, NORMALS direction should be set for OUTWARD. 1) the cylinder CYLINDER of workpiece STOCK usable VERICUT builds a model, set radius, length, the position that can set workpiece left end panel to be fastened in machine tool coordinate from the POSITION input casing of POSITION option, work of shift of facilitating left and right sides. 2) when main shaft chuck and card claw are added, center of chuck right end panel should locate in coordinate department origin is in, card claw transfers into after the model, cooperate fixed position with MATE, the 2nd, 3 card claw can rotate with ROTATE tool 120 ° get. 3) adjust part of part of tool carrier roll, should locate X, Z makes turn the center fastens origin in coordinate to the position, adjust Y direction position to make the position that hold a knife and knife handle bottom are contacted. 4) after other part can transfer into, use cooperate means to locate. (7) setting parameter chooses menu " → SETTING of SETUP → G-CODE " , playing a dialog box to be chosen " JOB TABLES " option, in the choice in casing of TABLE NAME list following parameter undertake additive: Machine tool of Initial Machine Location(is initiative positional) : 300 0 750 (coordinate of X Y Z uses blank space interval) ) of reference point of machine tool of Machine Reference Location(: ) of origin of process designing of workpiece of 300 0 750 Input Program Zero(: 0 0 200 (200 be apart from machine tool coordinate for origin of Z direction workpiece is origin distance) choose TOOL TABLES option, in the choice in list casing following parameter undertake additive: Date of cutting tool of Gage Offset Index () Values (dot of point of a knife slants buy value: Point of a knife is apart from to tool carrier center) 1 120 0 90 2 120 0 90 3 120 0 90 120 0 90 still has a few parameter, install like kind of program of the machine tool journey, means that change a knife, NC and collision etc, can have corresponding operation, here repeats no longer. (8) save a file to save MCH of file of CTL of file of system of user file USR, control, machine tool respectively. Make to facilitate VERICUT software begins to move to enter his user file namely, can edit VERICUT.
