• Page 13: Fundamental Geometrical Principles

  Fundamental Geometrical Principles Workpiece positions 1.1.1 Workpiece coordinate systems In order that the machine or the control can work with the positions specified in the NC program, these specifications have to be made in a reference system that can be transferred to the directions of motion of the machine axes.

• Page 14
  Fundamental Geometrical Principles 1.1 Workpiece positions Figure 1-2 Workpiece coordinate system for turning The workpiece zero (W) is the origin of the workpiece coordinate system. Sometimes it is advisable or even necessary to work with negative position specifications. For this reason, positions that are to the left of the zero point are assigned a negative sign («-«).

• Page 15: Cartesian Coordinates

  Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.2 Cartesian coordinates The axes in the coordinate system are assigned dimensions. In this way, it is possible to clearly describe every point in the coordinate system and therefore every workpiece position through the direction (X, Y and Z) and three numerical values The workpiece zero always has the coordinates X0, Y0, and Z0.

• Page 16: Fundamental Geometrical Principles

  Fundamental Geometrical Principles 1.1 Workpiece positions Example: Workpiece positions for turning With lathes, one plane is sufficient to describe the contour: Points P1 to P4 have the following coordinates: Position Coordinates X25 Z-7.5 X40 Z-15 X40 Z-25 X60 Z-35 Fundamentals Programming Manual, 07/2010, 6FC5398-1BP40-0BA0…

• Page 17
  Fundamental Geometrical Principles 1.1 Workpiece positions Example: Workpiece positions for milling For milling, the feed depth must also be described, i.e. the third coordinate (in this case Z) must also be assigned a numerical value. Points P1 to P3 have the following coordinates: Position Coordinates X10 Y45 Z-5…

• Page 18: Polar Coordinates

  Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.3 Polar coordinates Polar coordinates can be used instead of Cartesian coordinates to describe workpiece positions. This is useful when a workpiece or part of a workpiece has been dimensioned with radius and angle. The point from which the dimensioning starts is called the «pole». Position specifications in the form of polar coordinates Polar coordinates are made up of the polar radius and the polar angle.

• Page 19: Absolute Dimensions

  Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.4 Absolute dimensions Position specifications in absolute dimensions With absolute dimensions, all the position specifications refer to the currently valid zero point. Applied to tool movement this means: the position, to which the tool is to travel. Example: Turning In absolute dimensions, the following position specifications result for points P1 to P4: Position…

• Page 21: Incremental Dimension

  Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.5 Incremental dimension Position specifications in incremental dimensions In production drawings, the dimensions often do not refer to a zero point, but to another workpiece point. So that these dimensions do not have to be converted, they can be specified in incremental dimensions.

• Page 23: Working Planes

  Fundamental Geometrical Principles 1.2 Working planes Working planes An NC program must contain information about the plane in which the work is to be performed. Only then can the control unit calculate the correct tool offsets during the execution of the NC program. The specification of the working plane is also relevant for certain types of circular-path programming and polar coordinates.

• Page 28
  Fundamental Geometrical Principles 1.4 Coordinate systems Three-finger rule The orientation of the coordinate system relative to the machine depends on the machine type. The axis directions follow the so-called «three-finger rule» of the right hand (according to DIN 66217). Seen from in front of the machine, the middle finger of the right hand points in the opposite direction to the infeed of the main spindle.
• Page 29
  Fundamental Geometrical Principles 1.4 Coordinate systems Position of the coordinate system in different machine types The position of the coordinate system resulting from the «three-finger rule» can have a different orientation for different machine types.

  Fundamental Geometrical Principles 1.4 Coordinate systems 1.4.2 Basic coordinate system (BCS) The basic coordinate system (BCS) consists of three mutually perpendicular axes (geometry axes) as well as other special axes, which are not interrelated geometrically. Machine tools without kinematic transformation BCS and MCS always coincide when the BCS can be mapped onto the MCS without kinematic transformation (e.g.

  Fundamental Geometrical Principles 1.4 Coordinate systems Machine tools with kinematic transformation BCS and MCS do not coincide when the BCS is mapped onto the MCS with kinematic transformation (e.g. 5-axis transformation, TRANSMIT/TRACYL/TRAANG). On such machines the machine axes and geometry axes must have different names. Figure 1-7 Kinematic transformation between the MCS and BCS Machine kinematics…

  Fundamental Geometrical Principles 1.4 Coordinate systems 1.4.3 Basic zero system (BZS) The basic zero system (BZS) is the basic coordinate system with a basic offset. Basic offset The basic offset describes the coordinate transformation between BCS and BZS. It can be used, for example, to define the palette window zero.

  Fundamental Geometrical Principles 1.4 Coordinate systems 1.4.5 Workpiece coordinate system (WCS) The geometry of a workpiece is described in the workpiece coordinate system (WCS). In other words, the data in the NC program refer to the workpiece coordinate system. The workpiece coordinate system is always a Cartesian coordinate system and assigned to a specific workpiece.

  Tool change Tool change method In chain, rotary-plate and box magazines, a tool change normally takes place in two stages: 1. The tool is sought in the magazine with the T command. 2. The tool is then loaded into the spindle with the M command. In circular magazines on turning machines, the T command carries out the entire tool change, that is, locates and inserts the tool.

При нажатии кнопки с буквой +Т или -Т магазин вращается (режим JOG)?

Если вращается, то в режиме «выход в референтную точку» нажми Т+  или Т-  = магазин должен крутиться до срабатывания датчика.

Если не останавливается — ищи и проверяй сам датчик.

Вполне возможно, что концевик (тот, который на датчик действует) был на отломаном язычке (пожирнее, чем остальные и не обязательно на первом месте)

Если не вращается, надо знать весь цикл смены инструмента — что за чем идёт и где  нормальное положение каждого исполнительного органа)))))……..

Может зонтик подъехал и не вернулся назад или шпиндель, или не  отпустился дачик после наезда и съезда.

А может зонтик сорвался с места, когда с него (или он) выдирали инструмент….

На фотке зонтик стоит под шпинделем — запрет на вращение.

Найти способ вернуть его в гараж..Если ничего не мешает,можно попробывать нажать ручками золотник пневмо(гидро)цилиндра.

Всем доброго дня.

Небольшой отчет по попытке «победить» Sinumeric 840D в части заливки архива по причине сдохшей батарейки и ошибки 120202.

см. посты #1892……#1903

в двух словах станок стоял три года без движения и вдруг понадобилось его запустить.

при включении замигал станочный пульт и выскочила ошибка 120202 (нет коммуникации с PLC)

недолго погуглив было выяснено, что эта ошибка означает потерю информации в оперативной памяти NCU поддерживаемой батарейкой.

Заменил батарейку на новую. И радостно потирая руки начал плясать с бубном возле станка, пытаясь залить архивы NC.ARC и PLC.ARC

Архив NC.ARC ну никак не хотел заливаться. Всё время при старте заливки архива выскакивала ошибка 120202.

По ходу пьесы были измучены дилетантскими вопросами уважаемые участники сего представительного форума.

Выяснено, что для редактирования станочных архивов весьма полезна программа SinuCom ARC и WinPCin.

На просторах интерента был найден весьма обширный архив (порядка 100 файлов) на русском языке по Sinumerik 802/840. Готов дать на него ссылочку или залить сюда, но боюсь быть заподозрен в рекламе сторонних ресурсов.

Вобщем танцы с бубнами продолжались около недели. Безуспешно но познавательно.

В конце концов решил проверить может моя новая батарейка что в блоке с вентилятором в NCU уже сдохла, раз творится такое непотребное.

Извлек её вместе с вентилятором и начал мерять напряжение. Напряжение в норме -3.17V, ток при КЗ дает порядка 0.6 А. Тоесть батарея огонь! Обратил внимание, что проводки которые я вставлял в отверстия разъёма батарейки для измерения напряжения, в отверстия соседнего однотипного разъёма вентилятора входят весьма плотно, а вразъём батарейки весьма свободно. ЁПТ! вот где собака зарылась! Наверняка и в разъёме NCU с которым коннектится батарейка контакта нет, или есть но хреновый. Нашел разъём чтоб поплотнее проводки в него втыкались, старый разъём отрезал, новый припаял к батарейке и всё это хозяйство обратно вставил в NCU.

Архивы залились с первой попытки. Станок ожил!

Мораль сей басни такова: никогда не пренебрегайте проверкой соответствия комплектующих заявленным характеристикам и требованиям предъявляемым к ним. Особенно к неоригинальным комплектующим. Особенно к китайским анналогам.

Огромная благодарность участникам форума с никами Granenyi, Anabolik , Terex_&

%1 = номер канала %2 = номер кадра, метка %3 = номер ходового винта %4 = номер ведомого шпинделя

При соединении синхронный ход не может быть достигнут, если динамика шпинделей/осей сильно различается. Динамика зависит от множества установок: предустановка предуправления, данные блока параметров, в первую очередь KV, время симметрирования и т.п., режим предуправления и установочные параметры предуправления, режим работы FIPO, установки фильтра рывка и фильтра динамики, DSC вкл/выкл.

К ним относятся следующие машинные данные:

Если различная установка выбрана осознано, то ошибка может быть подавлена с помощью машинных данных 11410 SUPPRESS_ALARM_MASK бит21 = 1.

Удалить ошибку с помощью клавиши стирания или NC -START.

Продолжение программы:

В машинных данных 35014 GEAR_STEP_USED_IN_AXISMODE сконфигурирована ступень редуктора, на которой шпиндель должен находиться в осевом режиме. ЧПУ при переключении шпинделя в осевой режим проверяет эту ступень редуктора. При этом сконфигурированная в MD 35014 ступень редуктора сравнивается с сообщенной с PLC ступенью редуктора (VDI-Nst «Фактическая ступень редуктора A до C», DB31. DBX16.0..16.2). Если ступени редуктора не совпадают, то следует эта ошибка. При переходе в осевой режим с программированием M70 ЧПУ автоматически включает или запрашивает сконфигурированную в MD 35014 ступень редуктор. Если сконфигурированная в MD 35014 ступень редуктора уже активна, то смена ступеней редуктора не запрашивается. В обоих случаях M40 остается активной.

Реакции: — устанавливаются сигналы интерфейсов

22070 Блок TO %1 Просьба установить инструмент T= %2 в магазин.

Повторить сохранение данных Параметр: %1 = блок TO %2 = номер T инструмента

Ошибка возможна только при активной функции управления инструментом в NCK. Было запущено сохранение данных инструмента/магазина. При этом было определено, что в буферном магазине еще находятся инструменты (=шпиндель, захват. ). Эти инструменты при сохранении теряют информацию, с каким магазином, местом в магазине они согласованы.

При этом имеет смысл – если необходимо идентичное восстановление данных — чтобы на момент сохранения данных все инструменты находились в магазине!!

Если это не так, то при повторной загрузке данных будут присутствовать места в магазине, имеющие состояние «зарезервированы». Это состояние ‘зарезервировано’ после по возможности должно быть сброшено вручную.

Для инструментов с фиксированной кодировкой места потеря информации о месте в магазине равнозначна общему поиску свободного места с последующей установкой в магазин.

2. Разница факт. значений между обоими датчиками больше, чем значение в спец. для оси MD 36500 ENC_CHANGE_TOL («макс. допуск при переключении фактического значения положения»).

В зависимости от сигналов интерфейсов: «Система измерения положения 1» (DB 31 — 48, DBX 1.5) и «Система измерения положения 2» (DB 31 — 48, DBX 1.6) осуществляется активация соответствующей измерительной системы, т.е. с этой измерительной системой теперь будет работать управление положением. Другая измерительная система переводится в режим слежения. Если оба сигнала интерфейсов «1», то активна только 1-ая измерительная система, если оба сигнала интерфейсов «0», то ось паркуется.
