刀具补偿号
刀具补偿起刀时必须为G00或G01 左、右刀补的设置
刀具半径补偿（G41、G42、G40）
螺旋线进给G02/G03
说明 1.X, Y, Z 中由G17/G18/G19 平面选定的两个坐标为螺旋线投影圆弧的终点 意义同圆弧进给第3 坐标是与选定平面相垂直的轴终点其余参数的意义同圆弧进 给。 2.该指令对另一个不在圆弧平面上的坐标轴施加运动指令对于任何小于360 的 圆弧可附加任一数值的单轴指令。
G90 时为中间点在工件坐标系中的坐标。 G91 时为中间点相对于起点的位移量。
G28 指令首先使所有的编程轴都快速定位到中间点，然后再从中间 点返回到参考点。
一般G28 指令用于刀具自动更换或者消除机械误差，在执行该指 令之前应取消刀具半径补偿和刀具长度补偿。
自动返回参考点G28
利用G28从当前点直接回参考点：
该指令使刀具以F指定的进给速度插补加
工出任意斜率的直线， 指令格式如下： G01 X__ Y __ Z __ F __ ；
其中， X、 Y、 Z为直线的终点坐标， 可以是绝对坐标， 也可以是增量坐标， 不移动的坐标轴可以省略； F为刀具移 动的速度， 单位为mm/min。

Linux系统内存占用90%以上——解决方法
Linux系统内存占⽤90%以上——解决⽅法Linux系统内存占⽤90%以上，是否属于正常范围？Linux/Unix系统管理内存的⽅式和windows是不⼀样的，即便是⼀个负载很⼩的linux，跑⼏天后，内存占⽤量也将达到90%以上，即便⽆⼈访问，这个数字是完全正常的。
但是，这个内存占⽤量不会达到100%的，每天夜⾥系统都会执⾏/etc/cron.dail Linux/Unix系统是⾮常稳健的，虽然内存占⽤显⽰90%以上，但依然可保证365天以上⽆须重启。
对于Linux系统，评估其压⼒的主要指标是最近5分钟的负载指数：⽐如⽤w命令或者top去看，可以看到“0.70 0.35 0.01”这样的数字，分别表⽰5分钟内的1）有程序占⽤⼤量CPU，使⽤top命令来检查（看看是否有java程序锁死之类的故障）2）有程序占⽤⼤量内存，使得内存真正不够⽤了（这个才是真正需要加内存的时候），⽐如由于MySQL在较⼤负载下运⾏容量为GB级别的数据库导致内存不够⽤，需要给服务器插⼊更多物理内存3）磁盘系统读写故障，IO吞吐错误造成CPU负载上升，需要光盘引导进⼊单⽤户模式扫描修复磁盘，修不好就只能更换新硬盘了因此，对于Linux/Unix系统内存占⽤的百分⽐，⽆须过于关⼼，⼀般检查系统负载参数即可但也可以⼿动进⾏内存释放，具体操作如下：cat /proc/sys/vm/drop_caches⾸先,/proc/sys/vm/drop_caches的值,默认为0free⼀下查看当前内存可使⽤的较少，执⾏⼀下以下的命令，可以解决当前的问题echo 3 > /proc/sys/vm/drop_caches 结果cat /proc/sys/vm/drop_caches3再来运⾏free命令,发现现在的used为66MB,free为182MB,buffers为0MB,cached为11MB.那么有效的释放了buffer和cache. 。

二、导入新课:
利用G00与G01加工一个轮廓需要四个动作：
①快速进刀（G00指令） ②切削进给（G01指令） ③退刀（G01指令） ④快速返回（G00指令）
那么我们能否将这四个指令并成一个指令 从而简化我们的程序呢？

复习提问
G00、G01指令的编程格式是什么？ 利用G00/G01指令编制红色轨迹的程序。
某中型零件制造企业，接到500 件刀杆的生产任务订单，要求三天内完 成生产。订单提供刀杆的零件图纸。作 为数控车床操作工，要根据刀杆的零件 图和工艺卡的要求进行首件试生产，并 检测加工精度，以便实现批量生产。
归纳总结
当编程起点不在圆锥面小端外圆轮廓上时，注意锥度起点和终点 半径差的计算
在对锥度进行粗、精加工时，虽然每次加工时R值都一样，但每 条语句中R值都不能省略，否则系统会按照圆柱面轮廓处理。
思考：
如图所示为棒料毛坯 （直径为Φ55）的加工 示意图，钻孔后的内孔 直径是Φ26，编写其加 工程序。
友情提醒
循环起点Z值设置在毛坯右端面前面处， 注意R值的计算问题

Lubricate lever pins lightly. Keep contaminants away from the ram and cyl-inder. Store with the lever down and hydraulic p ressure released.Adding Hydraulic Oil1. Place the driver in a vise in a vertical position withthe handles up. Unscrew the reservoir handle and remove the bladder plug. Open the release valve knob to assure the ram is fully extended.2. Fill the rubber bladder to the point of overflow withGreenlee hydraulic oil.3. Purge air from the system: Pump the lever handle several times to remove airfrom the pumping chamber. Close the release valve knob and pump the lever handle until the ram com-pletes its full travel. Repeat as necessary.Note: Open the release valve knob slowly so the ram extends slowly. Rapid return of oil and air may cause the oil to overflow the rubber bladder. If this procedure fails to remove air, remove thebladder plug and open the release valve knob. Place thumb over the plug hole in the bladder and squeeze the bladder while pumping the lever handle several times. Close the release valve knob and pump the lever handle until the ram completes its full travel. Repeat as necessary. If this procedure does not remove air, remove theplunger (24) and fill the plunger cavity with clean oil as described in the “Reassembly” section of this manual.4. Fill the rubber bladder to the point of overflow andreplace the bladder plug. Wipe the bladder clean of excess oil and reassemble the reservoir handle.Oil Leaks• Check for external oil leaks.• Check that the release valve knob and stem are closed tightly and seating properly.• Remove the reservoir handle and check for oil leaks around the rubber bladder and bladder plug.Ram Section Will Not Rotate1. Loosen and readjust the set screw (13).2. Hold the punch driver with the ram section down.3. Apply a small amount of penetrating oil to the cyl-inder (1) at the attachment point, and then work the ram section back and forth.4. Apply a small amount of SAE 30 oil to the cylindercollar next to the pump block.Quick Draw 90® Hydraulic Punch DriverGreenlee / A Textron Company4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-70706TroubleshootingProblemProbable CauseProbable RemedyDoes not punch hole.Improper assembly or use of punch, die, or accessories.Refer to “Operation” and “Capacity and Draw Stud Selection Guide” inthe Instruction Manual.Low oil level.Refer to “Adding Hydraulic Oil” in the “Maintenance” section.Requires excessive lever force.Improper assembly or use of punch, die, or accessories.Refer to “Operation” and “Capacity and Draw Stud Selection Guide” inthe Instruction Manual.Material being punched is too thick or too hard.Refer to “Capacity and Draw Stud Selection Guide” in the Instruction Manual.Pump does not build p ressure.Air in system.Refer to step 3 of “Adding Hydraulic Oil” in the “Maintenance” section.Excessive number of strokes are required to punch hole.Inoperative intake check valve.Refer to “Intake Check Valve” inspection in the “Inspection and Adjustments” section.Inoperative discharge check valve.Refer to “Discharge Check Valve” inspection in the “Inspection and Adjustments” section.Leaking release valve.Refer to “Release Valve” inspection in the “Inspection and Adjustments” section.Damaged piston, piston extension, pump plunger seals, or mating surfaces.Refer to “Maintenance,” cylinder and pump block sections.Clogged filter.Clean or replace filter (40).Does not return piston.Weak or damaged return spring; excess oil in unit.Refer to “Ram Travel Inspection” in the “Inspection and Adjustments” section.External oil leaks.Damaged piston, piston extension, pump plunger seals, or mating surfaces.Refer to “Maintenance,” cylinder and pump block sections.Damaged release valve stem seal.Refer to “Release Valve” inspection in the “Inspection and Adjustments” section.Quick Draw 90® Hydraulic Punch DriverGreenlee / A Textron Company4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-70707DisassemblyPump SectionNote: Separate ram section from pump section.

If it is not, the bladder (29) contains too much oil.To remove excess oil:1. Remove reservoir handle (21) and bladder plug (20).2. Slowly open release valve knob (27); excess oilshould come out of the bladder and the ram should move to become flush to 1/64" (0.396 mm) below the end of the cylinder (1).3. If excess oil does not come out, replace thecompression spring (7).Ram RetractedMeasure ram travel distance (difference between ram completely extended and completely retracted). Distance is 0.830" (21.1 mm) to 0.930" (23.6 mm).Pump Section Inspection Intake Check ValveClose the release valve knob and operate handle (22) until ram (3) bottoms and handle resistance increases.• If the ram bottoms in 30 strokes or less, the inlet check valve (32 and 23) is operating properly.• More than 30 strokes indicates an inlet check leak. Re-seat, re-drill, or replace the inlet check seat (23).Discharge Check ValveIf the handle (22) returns to the raised position by itself, the discharge check valve is leaking. Re-seat or re-drill the discharge check seat and replace the compression spring (39).Install socket screw (26) to depth shown. If screw isbottomed out, ball cannot move and Quick Draw handle will not pump.Release ValvePump the handle until the ram bottoms. Gently apply and maintain additional force on handle (22). If thehandle remains solid, the ball (32) is operating properly. If the handle (22) goes down slowly, the release valve is leaking. Re-seat or re-drill the release stem seat and replace O-ring (33).Cylinder RotationInstall a 3/4" draw stud and a 2" conduit size punch and die to the punch driver. Hold the driver by the reservoir handle (21) so the draw stud is horizontal; the cylinder should not rotate from the combined weight of the draw stud, the punch, and the die. If rotation occurs, O-ring (14) may be worn.If binding or roughness occurs during cylinder rotation, check for lubrication or damage at threads closest to set screw (13); also check adjustment of set screw (13).10Greenlee / A Textron Company4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070Quick Draw 90® Hydraulic Punch DriverGreenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-707011Parts ListKey Part No. Description Qty1 50369148 Cylinder, angle driver (1)2 50369172 Block, pump (1)3 50369040 Ram, right angle driver (1)4 50369156 Plate, spring retaining (1)5 90518098 Retaining ring, 1.75 Truarc internal (2)6 90504526 Ball, steel, .218 diameter (1)7 50339079 Spring, compression, 1.34 x 1.65 x 1.76 (1)8 90538471 Backup ring, spiral, 1.00 x 1.24 x .027 Teflon (1)9 90513169 O-ring, 1.50 x 1.75 x .125 nitrile (1)10 90538498 Backup ring, spiral, 1.50 x 1.74 x .027 Teflon (1)11 90513304 O-ring, 1.00 x 1.25 x .125 nitrile (1)12 90510321 Screw, set, #8–32 x .187 socket cup point (1)13 90508815 Screw, set, 1/4–28 x .250 socket (1)14 90508971 O-ring, 1.37 x 1.62 x .125 nitrile (1)15 90508963 Backup ring, spiral, 1.37 x 1.62 x .121 (1)16 50318780 Decal (1)17 52081520 Decal, identification (1)18 90511301 O-ring, 1.50 x 1.62 x .062 nitrile (1)19 50232584 Grip, .600 x 1.00 x 4.50 (1)20 50324888 Plug, bladder (1)21 50368893 Handle, reservoir (1)22 50368877 Handle, pump (1)23 50368907 Seat, inlet check (1)24 50377159 Plunger (1)25 90538633 Pin, drive, .218 x .312 (1)26 90513371 Screw, jam, 5/16–24 x .156 socket (1)27 50368869 Knob, release valve (1)28 50368931 Stem, release (1)29 50342690 Bladder, rubber (1)30 52065581 Pin, handle (see note 1) (2)31 50342878 Spring (1)32 90506782 Ball, steel, .187 diameter (2)33 90538544 O-ring, .250 x .375 x .062 (2)34 90504585 Pin, roll, .125 x .375 (1)35 90517415 O-ring, 1.31 x 1.56 x .125 nitrile (1)36 90542304 Backup ring, spiral, .265 x .052 Teflon (1)37 50428270 Retaining ring (see note 1) (2)39 90538455 Spring, compression, .152 x .180 x .380 (1)40 52059251 Filter, oil (1)44 50368940 Cap, reservoir handle ................................................................................1Note 1: 52065581 handle pin (30) and 50428270 retaining ring (37) should be purchased together, replacing all previous pin designs.Quick Draw 90® Hydraulic Punch Driver4455 Boeing Drive • Rockford, IL 61109-2988 • USA • 815-397-7070An ISO 9001 Company • Greenlee Textron Inc. is a subsidiary of Textron Inc.USA Tel: 800-435-0786 Fax: 800-451-2632Canada Tel: 800-435-0786 Fax: 800-524-2853International Tel: +1-815-397-7070 Fax: + Draw Studs and AccessoriesCat.
