Numerical control turns treatment is high quality of machining industry government, high accuracy, tall n, efficient the trend of development. Combine our country actual national condition, lathe of economy numerical control is the it is important to reach its step that our country develops to numerical control lathe from common lathe. Use existing common lathe, undertaking counting accusing to change transforming to its is a low cost, cost-effective way. One, overall program: Graph the overall frame of system of 1 numerical control configures overall frame specification: 1, the PC can use labour to accuse a PC, can satisfy this control requirement that controls a system. 2, motion controls card. We used the PCL motion that produces by ADVANTECH company to control card. This calories are a kind of high speed 3 axes pace controls card into electric machinery motion, it has opening of 16 digital input, output, can achieve 3 axes linkage. Accordingly, it can satisfy lathe X, z axis linkage, implementation is linear, circular arc interpolation. 3, oneself design photoelectricity coupling circuit, its action is the signal concussion that can keep apart exterior interference signal to control card to motion, increase systematic stability. 4, machine tool noumenon is be transformed by C613 and come, demolish original filar staff, smooth board box, gear-box, withhold original 3 ungual chuck to wait. 5, the pace takes electric machinery and its drive is to use 4 firms of Nanjing. The 45V of input voltage type of driver, consideration pace receives the pitch of the step pitch horn of electric machinery and filar lever, the pulse equivalent of this systematic X axis is 0.

00125, the pulse equivalent of Z axis is 0.

0025. Can achieve completely 0.

The treatment precision of 005mm asks. 6, all sorts of spacing switch, decelerate switch, answer 0 switch to all be installed go up in machine tool noumenon, spacing switch is the effect that has this hardware hard spacing, when lathe machines workpiece to exceed size range of pipe bent, lathe stops automatically to machine. The action of decelerate switch is when lathe tool carrier is answered 0 walk along lathe near 0 o'clock when, decelerate switch is informed of lathe to decelerate takes null place by open. 2, the design of feed system considers system of this numerical control is open loop control, feedback without the position, reason feed system as far as possible should reduce intermediate transmission link. The X of this lathe, two axes of Z feed system take out the intermediate transmission link of original feed system, used a pace to enter tigidity of electric machinery ＋ directly the transmission plan of lever of silk of ball of shaft coupling ＋ . Demolish original filar staff, increase a few mechanical accessory, can install a pace to enter electric machinery and nut of ball silk lever deputy. According to computation, ask the pace enters electric machinery twist be apart from is 5 Nm. We choose a pace to enter the 86BYG250C-SAFRBC-0302 that electric machinery is 4 companies of Nanjing, step pitch horn is chosen 0.

9/1.

8, twist be apart from is 7.

5Nm. The model of driver is SH20806, inputting voltage is 45V. 3, the software part of system of this lathe control uses the software share that controls a system VC ＋ ＋ 6.

0 write, if the treatment interface of this software pursues 2. Its function basically has read the treatment G code that takes a part, edit and compile G code, emulation treatment (before including to machine, be emulated and emulate with treatment synchronism, wind reference point, be opposite by hand knife, treatment is interrupted, exceed the function such as Cheng soft spacing. It can treat feed rate, main shaft speed reachs rotate speed way, cutting tool information, a variety of treatment information such as M function. The operation platform of this software is Windows98. The unit process of cargo bandling of this software is to read in * above all.

NC or * .

The G code file of TXT; Undertake compiling next, compile implement the solecism clew that can give out not to accord with this software; The mistake also can be revised instantly; Input according to the real measure of wool embryo next, software makes be emulated before treatment. Below the condition that affirms the treatment that did not cause because of G code is wrong, can begin machine tool treatment. The be opposite above all knife before treatment, having work at building to the meaning of the knife must concern between coordinate and lathe coordinate. In machining a process, the condition column of software interface still shows the coordinate with current cutting tool, machine condition, the information such as handling time. Graph interface of software of system of lathe of 2 numerical control 4, main shaft system is transformed demolished original main shaft transmission case, use coder of ＋ of main shaft of ＋ of transducer ＋ leather belt. The main shaft speed of this system also is timing having class, in all 7 class, speed can arrive from 40rpm 1200rpm, the career that does not spend each archives can pass setting transducer to come true according to need. Use 5 terminal of transducer, can dominate electric machinery with digital amount, invert, stop to reach each archives rate. This transducer is the product below the pine, among them 7 archives frequency is installed in A20~A26, port should by port controller (A1) control. This system did not use manual and mechanical timing, all speeds all are controlled by the S command in G code. Software can be read take G code, rotate speed of electric machinery of automata main shaft. 5, after tool carrier structure changes his costume or dress as a result of this lathe tool carrier, can install two cutting tool only, one is used at turning common column, cone reachs end panel, one is used at machining whorl, reason was not used rotate type tool carrier, the around that cutting tool is tool carrier be been in by installation two end, use X axis around to walk along a knife to change a knife automatically in order to come true.
