广数车床G代码全解

广数车床G代码全解G00 定位1.格式: N_ G0 X(U)_ Z(W)_其中: X(U),Z(W)为定位的终点坐标,X,Z分别为X轴和Z轴的绝对坐标,U,W分别为X轴和Z轴的相对坐标,、相对坐标和绝对坐标用其中之一,不需移位的坐标轴可以省略,相对坐标是相对于当前位置的位移量。

2.对于两个轴需要定位的情况,总是先两轴同时按照较短轴长度快速移动，再快速移动较长轴的余下长度部分。

定位速度按照1号参数进行,可用H字段修改快速定位速度(41-43号参数为各轴限速) 例: 当前位置(250,400)：N400 G0 X100 W-300G01 直线切削进程格式: N_ G1 X(U)_ Z(W)_其中, X(U),Z(W) 为直线的终点坐标以当前位置为直线的起点, X(U),Z(W)字段给定的位置为终点进行直线插补。

进刀的速度为切削进给速度,可用F字段或2号系统参数修改切削速度使用步进电机时进给速度F<=1200.00可保证不失步。

例:当前坐标(100,300)：N100 G1 X50 Z200 F100G02/G03 圆弧切削格式: N_ G2或G3 X(U)_ Z(W)_ R_或: N_ G2或G3 X(U)_ Z(W)_ I_ K_第一种格式是用园弧半径R进行编程,第二种格式是用园心相对于起点(起点即当前位置)位置(I,K)进行编程。

使用步进电机时进给速度F<=1000.00可保证不失步。

其中, X(U),Z(W) 为园弧终点的坐标；R 园弧的半径；I 园心相对于起点的坐标在X轴的分量, G11状态为直径编程,G10状态为半径编程；K 园心相对于起点的坐标在Z轴上的分量；园弧插补是按照切削速度进刀的。

G2为顺时针方向,G3为逆时针方向,如图示：园弧插补自动过象限,过象限时自动进行反向间隙补偿。

用R 编程时.若R>0,则为小于等于180度的园弧,若R<0则为大于等于180度的园弧。

广数G代码（Gcode）

广数G代码（G code）G code. TXT - you are two boats and you are really beautiful. - everyone who says they don't want to be in love has an impossible person in their heart. I love every unhappy but still smiling child. If there is one person, I am invisible and know that I am waiting for someoneNumerical control lathes can be divided into simple numerical control lathe (economical numerical control lathe),multi-function CNC lathe and CNC turning center according to the function and mechanical composition of numerical control system.(1) simple CNC lathe (economical nc lathe) is a low grade of numerical control lathe, is often done with a single machine or single chip microcomputer control, mechanical part is designed on the basis of the ordinary lathe to improve.(2) the multi-function CNC lathe is also called the all-purpose CNC lathe, which is controlled by a special numerical control system and has the characteristics of nc lathe.(3) the CNC turning center increases the additional coordinate axes on the basis of CNC lathe.Main technical specifications of CNC lathe (CJK6153).The diameter of rotary diameter: phi 530mm. Rotary diameter of the maximum workpiece of the skateboard: 2280mm, the machine tool with the maximum distance of 1000mm, the maximum X direction of the tool frame: 260mm, the maximum z-direction ofthe tool holder: 1000mm. Manual 4 frequency conversion speed control 25 ~ 2000 RPM.4.1.6 numerical control lathe (CJK6153) lubrication and coolingThe lubrication of the machine tool and the lubrication of other parts are two parts. Have the headstock gear adopt oil lubrication, forced by cycloid pump lubrication, cycloidal pump oil absorption, first by the refined filter, and then into a magnetic filter, and then sent to each component of the spindle bearing or effects of oil lubrication and all other moving parts to forced lubrication and oil lubrication. Machine tools in other parts of lubrication, such as tail frame, guide rails and the screw nut adopt oil lubrication, the interval lubrication pump is adopted to X axis and Z axis of the guide surface and the ball screw nut lubrication, tail sleeve cylindrical parts such as automatic intermittent lubrication. In the transparent state tank, with a liquid alarm switch, the machine will lubricate the alarm when the oil in the box is below the regulation value. The machine cooling system adopts pump cooling. The daily maintenance of the cooling unit is mainly the replacement of the cooling water and the cleaning of the filter. It is strictly forbidden to start the cooling pump before the cooling liquid is poured in the cooling box to avoid burning the cooling pump. When cooling water is reduced, supply should be timely. The cooling water should be replaced when the pollution is bad. The cooling liquid should be selected to prevent rust.4.2 programming method of CNC latheIn order to learn the programming of CNC lathe, we must understand the operation point of nc lathe. Most of the existing textbooks do not use CNC lathe operation and programming as a whole.4.2.1 machine coordinate system for CNC latheThe machine tool coordinate system is the inherent coordinate system of the machine tool, it is the foundation for making and adjusting the machine tool, and also the basis of setting the workpiece coordinate system. The machine tool coordinate system has been adjusted before the factory, generally not allowed to change arbitrarily. Reference point is also a fixed limit point on the machine tool, and its position is determined by mechanical block or stroke switch. The machine coordinate system is confirmed by returning the machine zero. Before the machine is turned on, CNC lathe should be familiar with the panel of CNC lathe. The form of the panel is closely related to the numerical control system. It is easy to turn on the CNC lathe. The lathe of the distribution system. When the power is turned on, it is easy to turn on the power supply. After the machine is turned on, the table is returned to the point of origin (or reference point, which has a fixed distance to the origin of the machine tool). The return zero (reference point) step of the CNC lathe is: the switch is in the "back zero" position. Press the manual axis in the direction key + X, + Z to zero indicator light. If the work is not done, the error compensation and backgap compensation will not be realized. Setting the machine tool origin is directly related to the G54 instruction in programming.4.2.Set the workpiece coordinate system of CNC latheThe workpiece coordinate system is the coordinate system used in programming, also called the programming coordinate system, which is artificially set. The establishment of workpiece coordinate system is an indispensable step in nc lathe machining. Different systems have different approaches.1. Establishment method of Siemens 802S system workpiece coordinate system(1) turn the knife to the base knife (e.g. 1 knife).(2) in the MDA state, input T1D0 to make the knife fill 0.(3) machine tool return reference point.(4) use the test method to determine the coordinate origin of the workpiece. The end face of the cutting test. Z doesn't move. If the point is the origin of Z direction, then the zero point of the parameter is placed in the G54 of the directory, and the Z of the point is the negative value of A, that is, Z = -a. If Z goes to the left of the end, then enter Z = - (A +) in G54, return the car. And I'm going to do the same thing with the outer circle. The Z direction is back, and the machine tool coordinates of X direction are recorded, the diameter of the machine is measured, and the radius R is obtained. In the G54 X, input X = -(A + R), return the car.2. The establishment method of the workpiece coordinate system of the GSK980T system(1) use manual method to test the end surface.(2) when the Z axis does not move, the axis is withdrawn along the X-axis and the spindle rotation is stopped. 3. Measuring the distance between the end plane and the zero point of the workpiece coordinate system. Then enter G50 Z in the input method and run the sentence. 4. In the same way, a manual way outside circle, in the case of the X axis fixed return along the Z axis, and stop the spindle rotation, measuring the workpiece diameter X, the entry mode input G50X, run the other can.3. The establishment method of GSK928TC workpiece coordinate system(1) the outer circle of the car, along the z-direction, measured the diameter, enter the diameter value by InputX, enter the car.(2) the end face of the vehicle, along the X direction, the distance between the end and the origin of the work piece, input the distance value by InputZ, and then enter the vehicle.4.2.3 determines the position of the base knife in the work coordinate systemAfter the workpiece coordinate system is determined, the position of the knife (reference knife) in the workpiececoordinate system can be determined by the G50 instruction.4.2.4 determines the location of other knives in the artifact coordinate systemProcessing a parts often need to several different cutting tools, due to the deviation of the tool setting and tool itself every knife to the cutting position, the position of the tip is not coincidence, as users don't need to consider when programming tool, the deviation between need to determine the position of other knife in the workpiece coordinate system, it needs to be through to the knife. Different systems have different approaches to dao.1. Method of Siemens 802S system(1) select a knife as the base knife, press the parameter key and the tool compensation button, then press the new tool button, input the reference knife number and the edge (complement). If the base knife is 1, choose 1 edge (complement), then the cutter is T1D1.(2) call to the knife window, use the base knife car outside circle, Z to return the knife, in the X axis zero deviation of the knife window (because it is the base knife), press the calculation key to confirm.(3) call each other cutter, determine the number of the knife and the edge of the knife, enter the diameter of the outside circle and the end of the car. Enter negative values for the depth of the steps. Calculate and determine.The wide range GSK980T system for the dao(1) use the benchmark tool to test the workpiece, and set the reference frame: test the end face X to return the knife, enter the input mode, press the program button. Enter G50 Z0, which is to use the end face as the z-base level. Then press the set key, set the offset number (the benchmark knife + 100), enter Z = 0, try to cut out the outer circle, Z to the back knife, measure the outer circle diameter, enter the input mode, press the program button. Enter G50X, then press the setting key, setting the partial number, the base knife offset number + 100, X =.(2) call each other cutter, outside circle, Z to return knife. If the diameter of the outer circle is measured, the measured value is set to the one offset, which is the value of the knife number + 100, such as the knife number 2, and the offset number is 202, where X =. Similarly, the steps of the car, X to the back of the knife, the depth of the steps, the input Z = - in the offset sign.3.The wide GSK928TC system for the dao method(1) use the base knife to try to cut the workpiece, use the input to establish the frame of the knife, the Z of the coordinate system is at the origin, generally located at the right end of the workpiece, which is the end of the test cut as Z to the zero.(2) call other knives, such as knife 2, to make a T20 call, then try to cut the outer circle Z to the back of the knife, measure the diameter, and then press the I key. The input. Cut the steps, X to the back, measure the depth of the steps, then press the K key, input - the knife patch is set.4.2.5 axis directionThe direction of the center of the center of the center to the center of the center is the positive direction. The axis perpendicular to the spindle axis in the horizontal plane is the X-axis, and the direction of the rotation center of the spindle is in the positive direction.4.2.6 diameter or radius programmingThe radial dimensions of the processed parts are indicated in the diameter of the drawing and the measurement of processing, so it is more convenient to use diameter size programming.4.2.7 general programming methods1. Determine the location of the first knifeThe g50x Z directive determines the position of the first knife, which requires the first blade to be moved to the position of X Z.2. Return reference pointsG26 (G28) : the X Z axis also returns the reference point, G27:the X axis returns reference point, G29: the z-axis returns reference points.3. Quick positioningG00 X Z quickly locates to the specified point.4. Linear interpolationG01 X Z F is used for outer circle and end surface. F is the feed rate, whose unit is mm/min (specified in G94 or G98) or mm/r (specified in G95 or G99).5. Arc interpolationG02 (03) X Z I K F is used for the car to be rounded or reversed. X Z is the endpoint of the arc, I K is the coordinate of the center relative to the starting point, F is the feed velocity.6. Screw cuttingG33 (32) X Z P (E) I K this instruction for thread cutting, X, Z for threaded end point coordinates, P for metric screw thread (0.25-100 - mm), E for inch screw thread (100-4 teeth per inch), for the refund of the I K. The spindle speed cannot be too high when the thread is cutting, generally N by P is less than 3000, N is the spindle speed (RPM), P is the metric thread guide (mm).7. Delay or pauseG04 X, X is the number of seconds to pause, which is generallyused to cut the slot and keep the bottom smooth.8. Spindle speed settingM03 (04) S is used for the main axis clockwise or counterclockwise, the spindle speed is S, and its unit is m/min (specified by G96) or r/min (specified by G97). The M05 indicates that the spindle stops.9. End of programM02 (end at this point) or M30 (return program first sentence after the end).4.2.8 cycleBecause of the commonly used bar materials and forging materials, the machining margin is larger, which is a simplified programming. The CNC lathe often has different forms of fixed cycle, which can be used for many cyclic cutting.1. Outer diameter and inner diameter cycleG90x Z R F is used for simple turning cycle of external diameter and internal diameter, X Z is the cyclic endpoint coordinates, and R represents the circular cone surface circulation. The value of the cone is the difference of the diameter of the cone, the starting point of the circle is determined by the previous procedure, and F is the feed speed.2. Threading cycle of threadG92 X Z P (E) I K R L, the instruction is used for thread cutting cycle, X, Z for threaded end point coordinates, P for metric screw thread (0.25-100 - mm), E for inch screw thread (100-4 teeth per inch), I K for the refund of, R represents the diameter of the thread starting point and end point (for processing taper thread), L said thread, starting point is determined by the other programs on thread cutting cycle. G92 instructions differ from G33 instructions to G92 multiple automatic cutting threads.Face turning cycleThe G94 X Z R F is used for the simple turning cycle of the end face, X Z is the cyclic endpoint coordinates, and R represents the cone loop. Its value is the size of the cone (Z deviation), and the starting point is determined by the previous program, F is the feed speed.4. Grooving cycleThe G75 X Z I K E F is used to cut the slot loop, X Z is the cyclic endpoint coordinates, and I is the input value per X axis,K is the number of retreats per X axis, E is the offset of Z axis, F is the speed of feed, and the Z is cut off.5. Circular coarse vehicle complex cycleThe G71 X I K L F is used for the outer round coarse vehiclecomplex cycle, which is to write out the shape of the outer circle when the program is programmed. The system starts from the blank to automatically take out the circular shape of the outer circle. The loop cutting, parallel to the Z axis X for circulation coordinates, I for each X amount of feed, K for each X amount of return, L to determine the number of processing procedure in the shape of the cylindrical, F feed speed, G71 instruction period immediately decided to cylindrical shape processing procedures section.6. The end face coarse vehicle complex cycleG72 Z I K L F is used for the end surface rough vehicle complex cycle, which is to write the end surface processing shape when programming, and the system starts automatically out of the end loop shape from the blank. The loop cutting, parallel to the X axis Z for circulation coordinates, I for each Z axis feed quantity, K for the amount of return for each of the Z axis, L to determine the number of end face processing in the shape of a program, F feed speed, G72 instruction period immediately decided to end processing procedures section shape.4.2.9 tool compensationWhen programming, think turning point is a point, but in fact in order to improve the tool life and workpiece surface quality and tool tip into a circular arc radius is often, in order to improve the machining precision of workpiece, round head dao program, need for the tool radius compensation. Most CNC lathes have the automatic tool radius compensation function (G41, G42). This kind of CNC lathe can be programmed directly according tothe contour dimension of the workpiece.4.2.10 absolute coordinates and incremental coordinatesX and Z are absolute coordinates, U and W are relative coordinates.4.2.11 public system and inch size settingThe system size sets the instruction G21, the British system size sets the G20, the machine is in the G21 state after the power is on the system.4.2.12 circular arc to reverse the judgmentThe CNC lathe is a machine tool with two coordinate axes. Only the X and Z axes should be considered by the right hand rule. The positive direction of the Y-axis is pointed to itself in the judgment, (i.e. the negative direction along the Y-axis), and the circular arc of the x-z plane can be correctly judged by standing in such position.CNC lathe programming of typical parts。

4.1.4数控车床的分类数控车床品种繁多，按数控系统功能和机械构成可分为简易数控车床（经济型数控车床）、多功能数控车床和数控车削中心。

(1）简易数控车床（经济型数控车床）是低档次数控车床，一般是用单板机或单片机进行控制，机械部分是在普通车床的基础上改进设计的。

(2）多功能数控车床也称全功能型数控车床，由专门的数控系统控制，具备数控车床的各种结构特点。

(3)数控车削中心在数控车床的基础上增加其他的附加坐标轴。

4.1.5数控车床（CJK6153）的主要技术规格。

床身最大工具回转直径：ф530mm。

滑板最大工件回转直径：ф280mm，机床顶尖距1000mm，刀架最大X向行程：260mm，刀架最大Z向行程：1000mm。

手动4级变频调速25~2000转/分。

4.1.6数控车床（CJK6153）的润滑与冷却该机床的润滑分床头箱的润格及其它部件的润滑两个部分。

有齿轮变速的床头箱均采用油润滑，由摆线泵进行强迫润滑，摆线泵吸油时，先通过精制过滤器，再进过磁性滤清器而后送到各润滑部件或经分油器对主轴轴承及所有其它运转零件进行强迫润滑和喷油润滑。

机床上其它部件的润滑，如尾架、道轨及丝杠螺母等均采用油润滑，采用间歇润滑泵对X轴、Z轴的各导轨润滑面及滚珠丝杠螺母、尾架套筒外圆等部位进行自动间歇式润滑。

在呈透明状态的油箱内，带有一个液位报警开关，当箱内油液低于规定值时，机床会发出润滑报警。

该机床冷却系统采用泵冷却。

冷却装置的日常维修主要是冷却水的补给更换及过滤器的清洗。

在冷却箱内未灌入冷却液前，严禁启动冷却泵，以免使冷却泵烧坏。

当冷却水减少时，应及时补给。

冷却水发生污染变质时，应全部更换，冷却液应注意选择防锈性能好的，以免机床生锈。

4.2数控车床的编程方法要学好数控车床的编程，必须了解数控车床的操作要点，现有教材大多没把数控车床的操作与编程作为一个整体来讲。

4.2.1设定数控车床的机床坐标系机床坐标系是机床固有的坐标系，是制造和调整机床的基础，也是设置工件坐标系的基础。
