CNC lathe of cutter and working principle of the operation
Numerical control lathe to knife operating and working principle of the release date: 2017 - 05 - 24 clicks: 2503 times the manual programming, numerical control lathe operation input processing program into CNC system, the operation of the specific method is: first, through mechanical operation panel to start the nc machine tools, and then by the CRT/MDI panel input processing program, then run the processing procedure. 1) Start CNC machine operation (1) machine tool start button ON (2) the program lock button OFF2) EDIT operation (1) choose the MDI mode or EDIT mode (2) according to ( PRGRM) Health (3) input the program name type program address operator, after the number character according to the ( INSRT） The key. (4) typing procedures section (5) type the procedures section, according to (after operation instruction code 输入) The key. 3) Run program operation (1) the lock button ON automatic cycle way two (2), CNC lathe caller operation call already stored in the numerical control system process, the concrete operation methods through mechanical operation panel to start the first numerical control machine tool, then call processing procedures within the system, and then run the program. 1) Start CNC machine operation (1) machine tool start button ON (2) the program lock button OFF2) The caller operation (1) choose the MDI mode or EDIT mode (2) according to ( PRGRM) Key (3) the caller type program address operator, after the number character according to the ( 输入) The key. 3) Running program operation (1) the lock button ON (2) select automatic cycle mode (3) according to the automatic cycle button 3, numerical control lathe to knife operating CNC lathe knife method has three: try to cutting, mechanical cutting knife method and optical knife method. 1) Try to cutting knife cutting principle assumes that the rest out round the location change of cutting knife, although do not have a mobile tool rest, cutter coordinates also did not change, but the point is not in the same position, if not eliminate the change after the knife point position error, is bound to cause change knife after machining error. After the tool change point position error of calculation: & Delta; X = X1 - X2 Δ Z = Z1 - Z2 according to the principle of the knife, cutter replacement after CNC system records the point position error & Delta; X、Δ Z, if use cutter location compensation method to determine after the knife point coordinates, so that can guarantee the knives on the machining precision of workpiece. 2) Benchmark knife to knife operation (1) with a cylindrical turning tool cutting workpiece end face, the input to the numerical control system Z coordinates of point position. (2) with a cylindrical turning tool cutting cylindrical workpiece and measurement of cylindrical workpiece diameter, the input to the numerical control system of the workpiece outside diameter measured value, the point location of the X coordinate. 3) General knife to knife operation with cutting knife point on the workpiece end face and side intersection of busbar, the input to the numerical control system the Z coordinate of the location in which the cutting knife point and X coordinate. So, CNC system recorded the two different coordinates of point in the same position, calculate the tool change after general benchmark knife and knife point position deviation, and the tool position deviation compensation by nc system to eliminate tool change after the tip position deviation. Four, the modification and application of tool offset value after turning if cylindrical workpieces, the cylindrical workpiece diameter 0. 30mm。 This can need not modify the program, and by changing the tool offset value to solve, namely in the X direction minish the tool position offset value 0. 30 mm, so it is very convenient to solve the machining errors generated in machining.
