In former B2316 Long Menxi / undertake transforming on the foundation of planer, cancel former mill / dig transmission system, convert NUM1020 controls X/Z axis respectively (use at dig to cut) reach U/W axis (use at grinding) . Graph 1 sky is cut jump over the 1 machine tool after changing one's costume or dress main function convex / the dig of sunken form circular arc face is cut with grinding. Means of 4 kinds of loops: Dig cuts a circulation: Monolayer, one-way, not reversible, artificial interpose trades a layer: Dig cuts a circulation: Multilayer, successive and automatic, one-way, not reversible: Grinding circulates: Monolayer, two-way, reversible, artificial interpose trades a layer: Grinding circulates: Multilayer, successive and automatic, two-way, reversible. Note: One-way -- the cutting when workbench is ongoing, when backing down not cutting (dig) : Two-way -- workbench advancement and when backing down cutting (grind) : Cannot go against -- right feed of can left → (dig) : Reversible -- left → is right / right → is left ordinal feed (grind) : Monolayer -- deepness of penetration of a cutting tool is changeless, finish left → right or right → is left end after a treatment: Multilayer -- after finishing monolayer, increase a regulation to cut deep amount, a monolayer machines a loop. And can be offerred cut for nothing jump over a function, move with avoiding to disable, improve work efficiency (if pursue,1 shows) . The frame of work program already had been made up, stock CNC, the user requires an input only relevant (workpiece, semifinished product) dimension and craft parameter, form executable work program namely. Cutting tool (planing tool and emery wheel) the synchronism that positional operation and shift must maintain strict with the reciprocate of workbench, namely: Must wait for workbench to reach terminal place, just allow to carry out the operation of next cutting tool positions and shift, and must wait for cutting tool after operation completes and shift reachs the designated position, next positions just already allowed workbench to undertake the next time reciprocate. If destroy afore-mentioned synchronous relationships, issue breakdown information namely. In moving if produce unexpected emergency (like cutting tool damaged) can stop urgently interrupt, after removing trouble, break from which office is new start continue to execute subsequently order. Process designing method: It is with protruding dig exemple (fillister, protruding is ground, sunken grind) of process designing method is omitted: ① data-in (see a picture 2 reach) issueing a list: ② answers 0 reach building coordinate is (3) seeing a picture: ③ program block diagram sees a picture 4, the program sees a picture 5 with the graph 6. Graph 2 data-in pursue 3 building coordinate is a graph 4 advocate block diagram pursues 5 main programs (A) subprogram (graphic graph of B) subprogram %100 of width of workpiece of RL2 of radius of circular arc of workpiece of L1 of data of workpiece of watch of 6 subprograms data-in face (1/2)L3 workpiece height (among H) variable L4 the centre of a circle (O) and, the parameter process designing with main agile application, subprogram moves in order to and the E parameter that as machine tool PLC/CNC two-way information delivers. After transforming, the cutting efficiency of the machine tool and workpiece treatment precision had very big rise, the user is very satisfactory. At present this machine tool runs stability.
