One kind can turn the CAD/CAM method of bit-type face milling cutter

The development of industry of 1 foreword railroad, caused cast steel of large size, large surplus treatment and the development that repair course of study. In hub of switch, rail, wheel, link up with, heart dish used in the treatment that waits for a spare parts lots and lots of can turn bit-type face milling cutter, of these milling cutter introduce improved treatment greatly efficiency, reduced finished cost. My unit continued in last few years multinomial railroad is special can turn the treatment task of bit-type face milling cutter, in design and treatment process we fumble gave comfortable the CAD/CAM method with oneself, make here in order to introduce. 2 model the CAD/CAM of face milling cutter is shown 1 times like the graph, in the past model the three-dimensional model of face milling cutter wants to be finished in the ability on graphical workstation, because PC is medium what CPU reachs the performance that shows clip is great in last few years rise, in common 586 machine (basic configuration PII266/64MRAM/4M shows the type that puts above) on use the software that has three-dimensional model function to be like AutoCAD R14 to be able to come true model the three-dimensional model of face milling cutter is designed. The bit that shows according to be like 2 to pursue by treatment face eduction first in the design forms a plan, spread out the three-dimensional block diagram of bit group in the space again, the dimensional state diagram that makes every groups of bit finally and the parameter of each groups of razor blade comes to line out. Specific design technological process shows 4 times like the graph: The cutting tool that by the flow place of above the design gives can satisfy the need of treatment. After plan of 2 dimension production passes production to distinguish a works from drawing office, cutter hub entered stage of production namely, we used aborning oneself develop " can turn the dimensional angle computation of bit-type face milling cutter and treatment proposal " software, the horn after dip of the parameter tool cutting edge angle of each razor blade that programmer pursues production medium, blade, law, space is nodded wait for information to input the computer, the computer is calculated automatically and print position of the dimensional point of view that gives each bit that the course amended, treatment, treatment suggests (include to stand lie direction of mill choice, treatment, reasonable treatment is combined) wait for information. These treatment proposals are mature arrived the function of the machine tool and size range of pipe bent, machine program can be created in the program module that so simply passes into these values treatment face milling cutter. These program module include: Module of computation of treatment establishing mill, lie space of module of mill treatment computation, machining center nods a conversion module to wait. The flow of this software shows 5 times like the graph: A few parts of above can finish in PC, the labour that the program transmits MAHO800C via stringing together cable of form news report accuses production can be thrown on machine. The advantage of this kinds of 3 methods is beardless high-powered graphical workstation, common PC can be competent; Have fixed module, the workload of programmer is very small, and the support of software of process designing of beardless and special numerical control, manual process designing can achieve the authorized strength of complex program; Economy is practical, use convenient, the member that design and process designing member master very easily; Can expand other type can turn conveniently go in the design of cutting tool and treatment.
