CNC Machining of CTX400 turning center and process designing apply

Limits of rotate speed of main shaft of center of turning of CTX400E of parameter of machine tool technology is 25 ～ 5000r/min, chuck diameter is 200mm, c axis rotate speed is 100r/min, graduation precision ≤ 0.

04 ° , x is 20m/min to fast and floating rate, z is 24m/min to fast and floating rate. The machine tool deploys 12 knives, knife handle is DIN69880 standard 30 norms. Can deploy 6 motivation knife at most, dynamical knife is the biggest the diameter is Φ 13, top rotate speed is 2500r/min. 2.

The center of turning of main characteristic CTX400E of the machine tool uses four-axle three linkage configuration, linear axis X/Y/Z and rotate C axis, c axis circles main shaft to rotate. The machine tool is divided outside having general turning function, still have the end panel in the spare parts (G17) face of the circle outside mixing (G19) the function that aspirant travel mill machines. 3.

The operation interface of the machine tool operates interfacial cent to be 6 menu, if pursue,1 is shown. MACHINE menu is used at the handlers in treatment to undertake installing to all sorts of parameter of the machine tool; DINPLUS menu provides the window of program of handlers handiwork work out; PARAMETER menu offers handlers to wait for the window that has define and be changinged to the cutting tool in treatment, chuck, clamping apparatus and tip; SIMULATION menu is emulation window, adopt this bill of fare, can undertake test and verify to machine program; SERVICE offers the quick way of service and maintenance; TURNPLUS is module of automatic process designing. 2, system of numerical control of HEIDENHAINCNCPILOT3190 of configuration of CTX400 of brief introduction of system of CTX400 numerical control, move in Windows95 environment under, use " man-machine interaction, the graph supports " means has the job. 1.

Process designing of means of conversational type process designing needs to choose an input to process material from inside menu only appearance of finish machining of semifinished product of qualitative, part, spare parts, cutting tool chooses in knife library, set parameter of thick, finish machining, can make cutting tool way automatically. Because need not write the control instruction of each axis directly again, compare with common CNC photograph, although do not have the personnel of process designing experience and the personnel that cannot determine cutting condition by oneself to be able to achieve the authorized strength of the program inside cutty time, shortened substantially consequently treatment plans time, rose to machine efficiency. Graph 1CTX400E operates an interface 2.

Imitate of cutting tool method and examination machine tool pass G17, G18, G19 3 window machine a process to show in real time to the spare parts. Through cutting tool method the examination can is opposite the detail that machines a process undertakes test and verify, be not regular state to call the police to what appear in treatment, clew, make the program admits really become simplification, try cut time to be reduced substantially. Graph the 2 angle that differ 3 times for method simulative. Graph 2CTX400E emulates treatment sketch map 3.

Management of advanced cutting tool life is in cutting tool library, the record that passes the treatment load to every cutting tool and handling time and imitate, of cutting tool of can rapid judgement wear away, timely the person that remind treatment changes cutting tool, assure to have positive effect to machining the precision of the spare parts. 4.

Main shaft bear shows the main shaft bear to every cutting tool in the program is mixed rotate speed has a record, show go up in operation face plate, operation personnel can undertake anatomize to cutting parameter according to case of main shaft bear, achieve the result that optimizes cutting parameter. 5.

The CNCPILOT3190 of numerical control system that CTX400 of code of commonly used G provides CNCPILOT3190 system, if commonly used G code function expresses 1 to show. System of watch 1CTX400 numerical control is commonly used function of G code instruction 3, the spare parts that if the graph is shown 3 times,treatment example machines on turning center, use program language above all paragraph to car, mill treatment appearance feature undertakes descriptive as follows: FERTIGTEIL[FINISHEDPART]N21G0X0Z0N22G1X66.
