G72循环加工G72循环加工是一种常用的加工方式，它可以实现高效率、高精度的加工过程。
在G72循环加工中，设定加工次数、每次加工的深度、每次加工的进给量和切削量等参数，然后通过循环加工的方式，实现对工件的加工。
2. P、Q、U、W、F参数的含义P参数：设定加工次数，即工件需要加工的次数。
Q参数：设定每次加工的深度，即每次加工需要切削的深度。
U参数：设定每次加工的进给量，即每次加工需要进给的距离。
W参数：设定每次加工的切削量，即每次加工需要切削的距离。
F参数：设定进给速度，即每分钟进给的距离。
3. G00和G01指令的区别G00指令是快速移动指令，用于快速移动到指定位置，不进行加工。

图4-2-2 G71指令中Δu、Δw符号的确定 提示： ⑴ 有别于0系统其它版本，新的0i/0iMATE系统G71指令可用来加工有内凹结构的工件。 ⑵ G71可用于加工内孔，膗、Δ w符号见上图。 ⑶ 第一刀走刀必须有X方向走刀动作。 ⑷ 循环起点的选择应在接近工件处以缩短刀具行程和避免空走刀。 4．编程示例：
1．G72不能用于加工端面内凹的形体。
2．精加工首刀进刀须有Z向动作。
3．循环起点的选择应在接近工件处以缩短刀具行程和避免空走刀。
四、成型加工复合循环（G73） 1．概述：成型加工复合循环也称为固定形状粗车循环，它适用于加工铸、锻件毛坯零件。某些轴类零件 为节约材料，提高工件的力学性能，往往采用锻造等方法使零件毛坯尺寸接近工件的成品尺寸，其形状已 经基本成型，只是外径、长度较成品大一些。此类零件的加工适合采用G73方式。当然G73方式也可用于加 工普通未切除余料的棒料毛坯。 2．格式：G73 U（Δi） W（Δk） R（Δd）

The door handle should be in the 6 o’clock position in line with the length of the door when fully latched and the enclosure is sealed.Turn release screw counterclockwise and hold screw in that position to release initial catch from beneath enclosure flange.Handle should rotate clockwise to approximately the 9 o’clock position under spring action. The locking bars should have retracted from top and bottom of door and center latch cleared right hand flange.Reclose door against enclosure base. Turn door handle counterclockwise to the 6 o’clock position. You should hear two distinct clicks as you turn the handle.Handle should remain in this position.1234Testing Vault Hardware Latching and Enclosure Seal (Cont’d) Return to Step 3 to open door. Close the door on the base and turn the handle to the 6 o’clock position. Door should be sealed securely to the enclosure base.latching handle sooner.56Close the door and turn the door handle counterclockwise until the first “click” is heard. Move the disconnect handle to the ON position (do not force). If the disconnect handle can be moved, the defeater lever actuator is properly adjusted.Bulletin 1494F Disconnect Switch KitBulletin 1494F Disconnect Switch Optional Accessory List。

数值孔径和f数的关系
数值孔径和f数的关系光学系统的F数或数值孔径FDA59N30可用来表述光学系统对辐射的会聚能力。
F数定义为系统的等效焦距与入瞳直径(有效孔径)之比,记作F或式中J为光学系统的焦距;D为光学系统的光学孔径。
F数的倒数也称相对孔径。
需要指出的是,这里直接用r表示光学系统的焦距,没有区分物方焦距和像方焦距,是因为在通常的应用中,实际光学系统的物方和像方介质相同,故而公式(3-12)中光学系统的物方焦距和像方焦距在数值上是相等的,通常情况上说焦距时不予区分。
最后一个光学表面与后焦点间介质(像方空间介质)的折射率;叻′为会聚在焦点的光束的孔径角(会聚光束与光轴的夹角)。
数值孔径NA和F数都可用来表示光学系统的聚光能力,通常物在有限远时,如显微系统,较多使用数值孔径NA;而物在无穷远时,如望远系统,较多使用F数。
若光学系统在空气中使用,乃′=1,利用近轴光学理论做近似处理,可以得出光学系统的F数和数值孔径的换算关系通常数值孔径NA越大,即F数越小的光学系统的聚光能力越强。
从公式(3-30)可知,理论上数值孔径的最大值为1,即理论上光学系统的F数最小值为0.5,其物理意义是在焦点形成的光锥具有180°的角度。
由于像质太差,F数为0.5的光学系统是没有实用价值的。

Siemens 802D 指令与操作界面
一、SIEMENS802D 数控指令格式G指令——Siemens系统数控车床M代码其他指令子程序调用方法在一个程序中（主程序或子程序）可以直接用程序名调用子程序。
子程序调用要求占用一个独立的程序段。
举例：N10 L785 P3 ；调用子程序L785 三次N20 WELLE7 ；调用子程序WELLE7结束方法：用M2指令或RET指令结束子程序。
用RET指令结束子程序、返回主程序时不会中断G64连续路径运行方式，用M2指令则会中断G64运行方式，并进入停止状态。
二、操作界面CRT屏幕及键盘分布常用按键：MDA ：用于直接通过操作面板输入数控程序和编辑程序。
AUTO：进入自动加工模式.JOG：手动方式,手动连续移动台面或者刀具。
REFPOT：手动方式回参考点.V AR：増量选择.SINGLE BLOCK：自动加工模式中,单步运行.SPIN STAR：主轴正转.SPIN STAR：主轴反转.SPIN STP：主轴停止.RESET：复位键.CYCLE STAR：循环启动.CYCLE STOP：循环停止.：报警应答键。

再来看一年前的榜单：
▲2016年2季度购物中心关注餐饮品牌榜TOP20
来源：赢商网大数据中心
以购物中心关注的餐饮品牌TOP20为观察样本，前后对比，你会发现，一
年后依旧上榜的品牌只有9家，榜单上超过一半是新面孔。
与2016年数据相比：
星巴克、海底捞、西贝等业界大牌地位稳定;
现象级品牌喜茶排名跃升11位，探鱼、云海肴等口碑品牌排名亦有所上
夸张的，郑州大卫城某拉面品牌1.5个月便从商场撤出。新创品牌的上升通
道正在收紧。
30家店全部开在商场的W君对此深有感触
在某A级购物中心，正餐大品牌能签8年，本地代表品牌签5年，它们生
意稳定、交租及时。相反，轻餐小吃区是红海，通常只能签1年，在二线城
市租金最高达到800-900元/平，很多小品牌抱着钱挤破头还进不来。有些新
01
商场里，餐饮洗牌正在加速
▼
最近，朋友W给内参君发来一条消息，说他在逛郑州最繁华的购物中心
大卫城时，看到里面的餐饮品牌又迎来一轮新洗牌，尤其是负一楼的小餐
饮，品牌替换明显加快。
已经记不清，这是该商场第几次洗牌了。内参君去探场发现：
大卫城并不是个案。在距离它直线距离1公里左右的华润万象城：
B1F的面包新语被软欧包网红品牌openoven取代;
餐饮品类有四种：
1、引领消费潮流的品牌。比如上广深港、国外的餐厅，首次进京或首次进
中国。例如喜茶就是首次进京。即将开业的日本牛角烤肉就是首次进大陆。
我们期待引入全新的品牌给消费者，引领消费者消费方向和行业的发展方
向。
2、餐饮集团做的新品牌首发。细节品质有保证，运营有经验，而且他们的
承租能力很稳定。
3、代表餐饮消费升级类品牌。朝阳大悦城今年尝试引入了多个代表消费升
场开业时专门搭配一些新创品牌，以便给二次调整留出空间(而大部分新品牌
都成了炮灰)。
02
哪些品牌被出局了?
▼
购物中心越开越多，餐饮占比也从10%一路上升到50%以上。
近日，赢商网大数据中心发布了《2017年2季度购物中心关注餐饮品牌榜
TOP50》。

美式厨房、俄式厨房、年糕火锅、小龙虾也存在这类问题。
03
谁能成为商场餐饮常青树?
▼
据招商负责人介绍，虽然大悦城的餐饮竞争很激烈，汰换品牌也是在业内
出了名的能折腾，但如果签署了正常租期，并不会有外界所说的3个月关
店那幺残酷。业内3个月关店的店铺都是一些餐饮POP-UP店，仅签署了3
到6个月的合约。
以朝阳大悦城为例，在朝阳大悦城餐饮招商负责人张闯看来，目前倾向的
商场餐饮30%成了“炮灰”，最快一个半月就被淘
汰！
如今，购物中心越开越多，商场中餐饮占比也从10%一路上升到50%以
上。
然而，商场给品牌的成长周期也在大幅缩短，数据显示，商场餐饮淘汰期
从5年到3年到缩至1年。甚至，在一些A类购物中心，让一家餐厅撤场最
快只用1.5~3个月!
竞争越来越白热化，商场餐饮洗牌开始加速。你要如何成为幸存者?
6F的小南国撤店，表哥茶餐厅正在装修;
7F的潮堂撤店，海底捞火锅进驻;
7F的小天鹅火锅撤店后，目测换成了食通天旗下的掂档牛肉火锅
以前，商场通常会给品牌一两年的培养期、再有两到三年的红利期，而现
在，《中国餐饮报告(白皮书2017)》显示，类购物中心，关掉一家生意不好的餐厅最快只用3个月。更
大悦城刚刚推出匠心慢食主题空间拾间，落地效果就很理想。
内参君调查发现，早餐、酒吧、烧烤等购物中心传统少见品类，也因特
色经营开始展露苗头，三里屯通盈中心楼顶的theroof是夜店+酒吧，太古里
的桃园眷村是早餐，朝阳大悦城的薛蟠、串亭是烤串这些品类有助于打造差
异化的新竞争力。越好的购物中心，越希望在品牌上能够引领市场，向用户
不过两个月的，也属于此列;
(3)自创品牌眼高手低死。这两年太多小白和跨界人干餐饮，看啥热门就跟
风做个自创品牌，花大钱进了商业体，但产品研发、运营管理、品牌推广都
没有章法，小餐饮区大量前赴后继的炮灰就是例证;
(4)加盟店断血死。有些品牌很有名，但商场加盟店却生意惨淡，缺乏总部
后续运营、推广支持，或者供应链各自为战。水货加盟店有类似问题，一些
级的品类，包括举个栗子、文宇奶酪等小品类升级品牌。最近华中、华南的
购物中心出现了烤冷面、烤鸡爪、掉渣饼等超级单品店，北京也出现了倔驴
帮、噹哈驴火等对驴肉火烧品类升级的品牌。做得都非常有特色，在保证了
口味的基础上，升级了消费体验。
4、从未进购物中心，但知名度、消费者认可度极高的民间品牌。这类品牌
有意向升级品牌，提升形象和细节后会非常受欢迎。比如，今年5月，朝阳
四种死法：
(1)网红品牌流行死。来得快去得也快，名气常常大于产品。一旦新鲜期一
过，立马冷场。赵小姐不等位、很高兴遇见你、水货连续关店，基本
都在此列;
(2)大牌水土不服死。在港台和北上广做得成功，进一二线城市就不行，高
冷不接地气。成都利苑兰桂坊店、鼎泰丰来福士店关店，郑州万象城的小南
国、潮堂关店，都与此有关。还有一些街边店做到几十家，可进商场开店活
升;
九毛九、奈雪的茶、新石器烤肉等崭露头角的上升期品牌，以及牧之初
心、大开沙界、PizzaExpress等西式简餐首次入围;
漫咖啡、绿茶、优格花园、太平洋咖啡、炉鱼、弄堂里、大食代等品牌跌
出前20。
结合榜单数据和对中国购物中心第一梯队招商负责人的采访，内参君发
现，不管是被淘汰还是主动离开，从内在经营看，撤场的餐饮品牌无外乎有
