Pro/ENGINEER uses skill mediumly in numerical control process designing

The setting of the sets Pro/ENGINEER work way of 1 work way is very important, because Pro/ENGINEER is default,the method that start is the BIN folder that falls in Pro/ENGINEER installation method, all sorts of orders with the most important Pro/ENGINEER of this folder memory. If do not set working way, as the job undertake, the meeting is direct a spare parts file, assemble file, treatment file and corresponding Trail file to be saved folder is here medium, the government that gives a file brings very big trouble, must build oneself working list so, and can accomplish the classification of the file deposit, consolidate management. The means that working way sets is: Working way catalog chooses below file directory, after the route that chooses to need to install next and folder regard the job as method, it is OK to decide. 2.

2The system that the file of correct application Config of Config file is Pro/ENGINEER configures a file, can satisfy all requirements to Pro/ENGINEER almost, undertaking products plan process needs to be used not only, there also is very important parameter to install when undertaking the process is designed machining. Pass these settings, OK a Pro/ENGINEER is custom-built the working environment that wants for place. The parameter that often needs a setting in machining a process is below. (1) Mfg_auto_ref_prt_as_chk_srf: Choose Yes or No, be in 3, 4 with 5 axes " outline " and " groovy " in milling alignment, choose below default circumstance whole consult the spare parts regards an examination as curved surface, use at computation of these alignment " NC alignment " cutting tool method. (2) Mfg_info_location: Choose Top_left, bottom_right, use a setting " production information " the position of the dialog box. (3) Mfg_xyz_num_digits: Default value is 10, in CL data file, for data of X, Y, Z the dot installs digital digit. (4) Nccheck_type: Include: Vericut (default) , incite the Vericut that offers with CGTech company; Nccheck, use Pro/NC-CHECK. 2.

Department of coordinate of machine tool of skill of choice of department of 3 workpiece coordinate is some of the solid on the machine tool coordinate is, set fixed coordinate origin. In be machined actually, can choose workpiece to go up normally regarded numerical control program as origin, build department of coordinate of a workpiece for origin with this. The coordinate when application software undertakes programming is fastened even if the workpiece coordinate when effective treatment is. What workpiece coordinate fastens is reasonable and affirmatory, the workpiece when logarithm accuses process designing and treatment searchs very important. Machine precision to raise a part, program origin should choose the design in the spare parts as far as possible fiducial with craft fiducial on, be like to the workpiece that locates with aperture, compare for program origin with the center of aperture appropriate. Program origin also can be chosen in two perpendicular plane hand in a line to go up, it is to still use milling cutter no matter so measure a head to be able to find the place that crosses a line very easily. To the product with geometrical irregular appearance, wanting the particular case according to the product to choose workpiece coordinate is. Want to abide by the following principle normally: Search easily on the machine tool, process designing checks the convenient, machining error that causes with place reliably when convenient, small to knife error, treatment small etc. 2.

4 cutting tool are cut apply housing with the method design that cuts a work kind, orbit kind treatment means, if do not make special design, cutting tool meets what have cutting tool according to systematic calculative position be cut and cut, but sometimes personnel does not need programming this place. For example, to Bao Bi the milling of the product is machined, to reduce the axial cutting force of cutting tool, prevent workpiece to be out of shape, can fall in workpiece above all commonly knife position stiletto, when axial feed, requirement cutting tool from fall feed of axial of tool bore position, side edge milling, in order to reduce cutting force, prevent workpiece to be out of shape. Optimize in cutting tool method can cut to cutting tool in the function and cut a position to do specific design, this function can apply at whole housing treatment, also can be in designation workpiece layer or the position undertakes cutting tool is cut and cut a design. The method that uses actually has 3 kinds: Build or choose datum mark to be cut as cutting tool axial with the position that cuts, this the dot is OK and umbriferous arrive perpendicular on all treatment layer at safe face; Build or choose what fiducial axes has cutting tool to be cut and cut positional design, this axes can be workpiece those who go up, also can be semifinished product those who go up, must perpendicular at safe face, of axial of same cutting tool cut the position that be being cut is edge axes; With careless draw tool, undertake cutting tool is cut on the XY plane that in treatment coordinate fastens design with the contrail that cuts. The careless draw function that can use Pro/ENGINEER software cuts the way that cuts a product to undertake designing to cutting tool, can make law of outline of spare parts of cutting tool edge to perpendicular cut perhaps make outline of spare parts of cutting tool edge tangential cut, can control cutting tool to cut the outspread distance that cuts. 2.

The orbit treatment means that the cutting tool method when 3 contrail are machined optimizes design Pro/ENGINEER gives programming the freedom with very large staff degree, can undertake according to different treatment product cutting tool machines the design of orbit. It is 4 kinds of means that machine orbit design below. (1) careless draw cutting tool machines orbit. (2) the side that chooses curved surface regards cutting tool as orbit. (3) choose curve of careless perhaps draw to regard cutting tool as orbit. (4) choice curved surface machines orbit as cutting tool. To a few paragraphs discontinuous contrail is machined, below the menu that can optimize in cutting tool method, rise through inserting means to join discontinuous treatment process, have cutting process no longer repeat a design, make machine a process to design more forthright. Particular way is: Menu is optimized to fall in cutting tool method, section thrusts way of new cutting tool contrail, and be below orbit treatment means can be opposite of radius of the athletic way of cutting tool, cutting tool slant buy direction undertakes controlling, the deepness direction that can ask to have cutting tool according to machining the structure of the product slants buy. 2.

Department of coordinate of treatment of machine tool of 4 5 axes changes skill to be in design of course of 5 axes treatment, the direction of axis of workpiece X, Y, Z wants to decide only, two axes also decided the others. The 5 axes treatment that curved surface and outline have below the circumstance normally can apply workpiece coordinate to fasten directly, but man-hour is added in bulk milling and housing milling, also can involve the mutual changeover between workpiece coordinate department and department of labor situation coordinate, in these two kinds treatment means falls, can offer 3 axes to machine means only, the Z axis way that cutting tool axes must tie along workpiece coordinate is machined, if the housing position on the spare parts is relative,workpiece coordinate fastens the point of view with had rotated proper, 3 axes means cannot generate cutting tool to machine orbit. Need to be versed in to this the coordinate department of pace application undertakes translation rotates at this moment, make be versed in mutual transition has between pace coordinate department and workpiece coordinate department namely. Specific means is: To needing to rotate in 5 axes treatment angle has housing or the product that bulk processes, redesign labor situation to machine coordinate department and relevant safe aspect, choose this coordinate department and safe side in this labor situation, make cutting tool edge perpendicular the Z direction feed that fastens at new coordinate, if the graph is shown 2 times,the changeover between coordinate department concerns. Graph department of coordinate of treatment of 2 5 axes changes sketch map among them CS0 -- workpiece coordinate is; CS1, CS2 -- the treatment coordinate after rotating is. When generation processes NC document, coordinate of automatic computation workpiece ties the system and the position of department of new labor situation coordinate affects, automatic when creating machine program the knife cutting tool the coordinate that dot conversion fastens into workpiece coordinate is numeric, in realizing process of a treatment, different coordinate fastens the changeover between. 2.

The controls Pro/ENGINEER treatment module of precision of treatment of treatment of 5 curved surface offerred the way that two kinds of curved surface machine: Conventional Surface Milling (groovy curved surface is machined) with Contour Surface Milling (contour line curved surface is machined) . Control of curved surface precision is the important segment in curved surface treatment, connect parameter of regular meeting application to control curved surface precision. (1) TOLERANCE points to tolerancepublic errand. Basically use curve of control cutting tool to machine the precision of method, when cutting tool takes a knife by linear interpolation, the two the biggest span that connects line and ideal curve uses tolerancepublic errand control, if pursue,3 are shown. Tolerancepublic errand numerical value is less, criterion curvilinear precision is taller. Graph sketch map of 3 public errand (2) SCALLOP-HGT: When milling cutter of use ball head machines curved surface, after cutting tool walks along a knife twice to pass, in workpiece the surface can form table of a protruding, if pursue,4 are shown. This parameter basically uses sketch map of parameter of graph 4 SCALLOP-HGT to control curved surface to machine medium protruding stage height, when the step pitch in be being expressed according to parameter when ball head knife machines curved surface, if form when protruding stage dimension exceeds this parameter to set a value, the system is automatic the step pitch according to cutting tool of this dimension recount, ensure the precision of curved surface asks. 2.

The cutting tool position that the development application Pro/NC of 7 aftertreatments program creates ASC Ⅱ form (CL) data file, before undertaking any treatment are operated these files need to undertake an aftertreatment in order to found " treatment dominates data (MCD) " file. Can control the aftertreatment module that should use through installing configuration option NCpost_type. After undertaking the product machines a design, the aftertreatment with need corresponding application implement the Dao Weiwen to generation undertake postposition is handled, in order to generate the NC code that the machine tool can identify. Because the structure of every kinds of equipment, function and use numerical control system are endless identical, aftertreatment implement cannot general, the person that need is used undertakes 2 times developing in the light of the numerical control system of specific facility, if pursue,5 are shown. The aftertreatment that opens the correspondence of system of different numerical control that give out implement, can handle the document of cutting tool method of different type format, do optimize processing to machine demand in order to satisfy the machine tool of different type, system, spare parts, generate NC program not to need to be done 2 times artificially revise and apply at the machine tool directly. Graph 5 aftertreatments program develops an interface above of 3 last words is the skill of a few application that the summary after the author is applying Pro/ENGINEER software to undertake programming comes out and experience. Examine actually through be being reached to the programming of a large number of spare partses, the MFG of application software machines module to be able to undertake the treatment process of product of of all kinds and complex structure is designed, apply advanced curved surface to machine module to finish product of complex curved surface among them CNC Machining of 5 axes machine tool, of the crucial technology such as the treatment that uses technology of high speed milling to have structural member of thin wall much housing, treatment of high accuracy product solve, obtained good technical economic benefits. When undertaking programming, still need to consider cutting tool method and program to optimize, of cutting parameter and cutting means optimize wait for a problem, below the premise that asks in contented products plan, reduce finished cost, improve the manufacturing efficiency of the product.
