Mill of plane of large work train in excess specified length gets the emulation analysis of special machine tool and research

5 μ M is the following, flatness is more than inside 20ml limits 1.

5mm. Home has not have treatment to exceed the requirement of long large gate so at present. Be aimed at this kind of circumstance, we study and design a kind to be made easily, cost planar mill gets the low, large work train in excess specified length that has innovation special machine tool. The article applied Pro/E, ANSYS and ADAMS software integratedly to undertake emulation analysis and research to system of special machine tool. The milling circumstance that differs when the job through true simulation machine tool, undertake to the machine tool trends is emulated, slideway of the machine tool that seek solution and procrastinate board osculatory circumstance and the working load that machine tool slideway gets, the analysis studies the trends of the machine tool is characteristic, undertake an analysis to emulating a result. System of machine tool construction of system is shown 1 times like the graph. 1 special machine tool is three-dimensional and hypostatic of the model build what build mill to get special machine tool with Pro/E is overall when the model, build model of all spare parts above all, next according to assemble a relation to undertake constructional. Because build overall the purpose of the model is this the model sends a person much style undertakes athletic emulation in kinetic software ADAMS.

And position of the component part quality that ADAMS emulates to undertaking only, centroid, moment of inertia has a demand, and feature of specific to its geometry does not care. Graph the 2 mill that build to use Pro/E get special machine tool three-dimensional and hypostatic model. The emulation of fictitious prototype analyses 2 machine tools 2.

1 machine tool is strong of soft coupling body build to study lathe bed crossbeam and procrastinate board of the collision between and lathe bed crossbeam be out of shape circumstance, turn into lathe bed crossbeam flexible body, what build lathe bed crossbeam in ANSYS is finite yuan of model, guide the person arrives in ADAMS again, procrastinate with frame type board assemble make system of firm soft coupling. MECHANISM/Pro module is the interface module that links Pro/E and ADAMS, both use without the means that seams a link, do not need to exit Pro/E application environment, OK its motion concern defines the product assembly basis that will assembled each rigid body and bring to bear on tie, convey the model again in ADAMS/View, undertake comprehensive kinetic analysis. Define 16 rigid body in all in whole machine tool, to determine the obligation between rigid body, mark point is defined on every rigid body, whole machine tool defines 19 mark point in all. In assembling good model to input ADAMS through Pro/E and ADAMS interface. ADAMS/Flex is flexible analytic module is one of ADAMS software package compositive and optional module, it was offerred ADAMS and finite yuan of analytic software ANSYS, NASTRAN, ABAQUS, I, the two-way data interface between DEAS.

Use these software to be able to be built flexible of body spare parts finite yuan of model, undertake specific finite yuan of analysis, make mode neutral file next. What build lathe bed crossbeam in ANSYS is finite yuan of model, use differentiate automatically reseau, unit type is Solid92, lathe bed crossbeam plans to divide unit amount in all for 42543, division check the number is 85875. 26 hard spot are defined on lathe bed crossbeam, these good name a person for a particular job input the bound noodle in ADAMS from ANSYS as the model.

In ADAMS these name a person for a particular job have join other component and the action place that serve as force. Between lathe bed crossbeam and pillar force of definition axle sleeve comes imitate the active force between them concerns, procrastinating board with lathe bed definition contact force comes to imitate between crossbeam their concern that asks active force, and osculatory force must be to be in firm 65 with define between rigid body, reason must be in lathe bed crossbeam and procrastinate board osculatory place brings to bear on fictitious other people 65, fictitious object and lathe bed crossbeam use fixed deputy coupling, in fictitious object and procrastinate board between the definition contacts force. 2.

2 milling force is calculated 2.

3 kinetic emulate the circumstance in stable state cutting to fall, to procrastinating board as big as lathe bed fine grain undertakes athletic emulation study. The setting runs length to be 1250mm, floating rate is 250mm/min, time cycle is 300s, the condition between Wl- is chief for 0.

018. The machine tool is kinetic emulate see a picture 4. Because lathe bed crossbeam and casing type procrastinate board between 7 pairs of slideway close suitably, define 7 contacts force to come respectively crossbeam of imitate lathe bed and casing type procrastinate board the osculatory circumstance between each slideway. Below the different cutting case that shows in following watches, procrastinate to lathe bed crossbeam and casing type respectively board osculatory circumstance undertakes emulation comparative. Fall with the 1st kind of operating mode below, the first pair of slideway (triangular slideway) the contact is exemple, to lathe bed crossbeam and procrastinate board asking osculatory force and osculatory moment of force have consideration. Graph the force of direction of the 5 X that suffer for triangular slideway place, Y, Z. The size of FX and FZ is equal, direction is mixed with X axis respectively Z axis to contrary; Fr is lesser, direction and athletic way are opposite, for the attrition force of slideway face. Graph the 6 circles axis of X, Y, Z moment of force that get for slideway place. Among them, the size of TX and TZ is basic and equal, TX and X axis to identical, TZ and Z axis to contrary; Tr is lesser, direction and Y axis to contrary. By go up knowable, slideway face is the triangle to basically accept force scale, flank slideway and bottom slideway restricted casing type to procrastinate board tipping. Other 3 kinds of circumstances, same method seeks solution on in order to. 3 conclusion used software of Pro/E, ANSYS, ADAMS to undertake emulation an analysis to the machine tool, by 3 software the machine tool of compositive development is fictitious prototype effective, physical prototype can be replaced on certain level. Through the machine tool fictitious prototype emulates research, beg the cutting situation with a different machine tool and lathe bed crossbeam be out of shape circumstance, beg a lathe bed further crossbeam and procrastinate board asking osculatory force and osculatory quadrature, for computation the load of lathe bed crossbeam provided new method.
