GibbsCAM machine tool emulates custom-built flow

Be a GibbsCAM software with QTT65 machine tool is the whole world the leader of respect of advanced CAD/CAM technology, in the car, mill, che Xi is compound with much task compound treatment domain has 20 old experience, become the leader of this domain. Machining a respect to machine a domain in MTM much task especially is to be in more get army position. Treatment of MTM much mission gets army positional requirement: The machine tool emulates a function. When facing more complex campaign structure, gibbsCAM can found a machine tool according to proper motion of structure of actual machine tool, undertake the machine tool is emulated, join synchronism government implement, adjust a program, make much knife tower much the program of main shaft with optimization, the most reliable means synchronism moves, ensure safety is machined. We will are with QTT65 machine tool below exemple, introductory GibbsCAM machine tool emulates custom-built flow: One, the machine tool builds a model 1.

Machine tool model can use CIMATRON or other software modelling is finished, guide notice each component become independent each other when the model (be not shirt-sleeve condition) . 2.

The dimension of the machine tool wants to be measured actually, according to client demand, general and accurate draw gives main shaft and knife tower position and relevant interference part. 3.

All components notice to agree with dimension of position of actual machine tool as far as possible when modelling, double main shaft and beard of double knife tower are on same plane (also some machine tool main shaft and layshaft are in X to it is abhorrent) . 2, machine tool sportswear matchs 1.

Model of to load machine tool, enter compose to build a machine tool. Assemble the position that notices coordinate fastens when the machine tool: Coordinate is fastened in machine tool origin, and the documentation that puts lay aside to had been assembled with XY coordinate department. Position of machine tool origin is in center of main shaft chuck, z to the position because of different machine tool differ somewhat. 2.

After window of set of machine tool imitate is opened, click increase pushbutton, the machine tool component that collect should define (yellow shows after collect) , be based on ROOT catalog, the name names for " fiducial " , axial label " J " . Open color dialog box to be able to define standard facial expression. This component is blame motion component. Click affirmatory, the definition is finished. We define fluctuation knife respectively from the back tower and advocate the motion of layshaft concerns. Nextpage3.

Knife tower group defines on: 1) go up definition of axis of knife tower Z1: Component of collect Z1 axis, in " fiducial " casing of text of the name below catalog is inputted " on knife tower Z1 " (the name is OK define oneself according to the habit) . Axial label is inputted " Z1 " (notice axial label " Z1 " it is fixed, each axis also is used under the proposal is fixed label) . Z1 axis is Z to sharp movement, axial shift is inputted in blank space of wh which direction namely along which 1 or - 1 (+ - 1 represent different vector way respectively) , so setting of mobile direction parameter is: "X0, y0, z1 " , notice Z1 axis vector. 2) go up definition of axis of knife tower X1: Component of collect X1 axis, in " on knife tower Z1 " accede below catalog " on knife tower X1 " , axial label is " X1 " . Setting of mobile direction parameter is: "X1, y0, z0 " . Axis of Y1 of tower of the knife on 3) defines: Component of collect Y1 axis, in " on knife tower X1 " accede below catalog " on knife tower Y1 " , axial label is " Y1 " , setting of mobile direction parameter is " X0, y1, z0 " . Bit body of tower of the knife on 4) defines: Component of collect bit body, in " on knife tower Y1 " accede below catalog " on K1 of knife tower bit body " . K1 axis circles Z axis whirligig. So setting of parameter of axis of rotation is " X0, y0, z1 " (circle which axial to rotate must be in which axes blank space is inputted 1 or - 1) . Still must appoint additionally rotate center, k1 axis rotates the center is center of bit body area, center of area of collect bit body, click " begin from the choice " can be record in bit of coordinate automatically " X350, y0, z379.

49 " . Nextpage4.

Leave definition of knife tower group: Collect issues package of axis of knife tower Z2, the attention is in " fiducial " accede below catalog " Z2 of tower leaving a sword " , axial label is " Z2 " . Setting of mobile direction parameter is " X0, y0, z1 " , notice Z2 axis vector is mixed on vector of knife tower Z1 is consistent. Alexandrine knife tower sets component of other of tower leaving a sword value, no longer tired narrate. 5.

Main shaft definition: The distance fibril between the two main shaft when making a machine tool is written into MDD according to the actual distance of machine tool origin, and distance of the two main shaft when modelling and MDD numerical value should keep consistent: Z 0 of main shaft origin, origin of deputy main shaft is in Z 728.

98 (origin parameter from door get in machine tool setting) . MDD advocate layshaft setting: Main shaft Z:0, layshaft Z:728.

981) main shaft definition: Component of collect main shaft, the attention is in " fiducial " accede below catalog " main shaft C101 " , axial label is defeated for " C101 " , axis of rotation is " X0Y0, z1 " , rotate the center is " X0Y0, z0 " . Nextpage2) main shaft machines spare parts definition: Collect main shaft machines a spare parts, in " main shaft C101 " accede below catalog " spare parts P101 " , spare parts label is " P101 " . Athletic condition is installed " fixed " . 3) definition of component of Z102 of deputy main shaft: Component of Z102 of collect deputy main shaft, the attention is in " fiducial " accede below catalog " Z102 of deputy main shaft " , axial label is defeated for " Z102 " , setting of mobile direction parameter is " X0, y0, z1 " (deputy main shaft but Z to athletic) . 4) definition of C102 of deputy main shaft: Component of C102 of collect deputy main shaft, the attention is in " Z102 of deputy main shaft " accede below catalog " C102 of deputy main shaft " , axial label is defeated for " C102 " , axis of rotation is " X0Y0, z-1 " (notice deputy main shaft rotates vector and main shaft are contrary, input so - 1) , rotate the center is " X0Y0, z0 " . Nextpage5) deputy main shaft machines spare parts definition: Collect deputy main shaft machines a spare parts, in " C102 of deputy main shaft " accede below catalog " spare parts P102 " , spare parts label is " P102 " . Athletic condition setting is " fixed " . 6.

The setting of knife tower: Click setting pushbutton, in the setting parameter dialog box is ticked off choose MTM, install 2 groups of cutting tool group group, install two groups of cutting tool respectively again group the origin of the group, notice with the machine tool origin of actual cutting tool is united. Above knife tower is exemple, install K1 of runner shaft coming back, this cutting tool group is 12 knives tower. Origin rotates for bit body namely position of rest, set position of rest to be 0 ° , step pitch is - 30 ° , the axis rotates the type is commonly the shortest. Setting of tower leaving a sword consults on knife tower. 7.

Motion examines after the setting is finished the relationship is reasonable, store athletic package finishs a machine tool to found namely. Nextpage8.

To load founds a machine tool to undertake emulation imitate: 9.

Notice the use of label of the axis when the machine tool assembles: The proposal when the machine tool is assembled uses fixed label, enumerate is as follows: X1, y1, z1, a1, b1, c1, k1 X2 of label of group of tower of the first knife, y2, z2, a2, b2, c2, k2 X3 of label of group of tower of the 2nd knife, y3, z3, a3, b3, c3, k3 label of group of tower of the 3rd knife.
