    Fundamental Geometrical Principles Workpiece positions 2.1.1 Workpiece coordinate systems In order that the machine or the control can work with the positions specified in the NC program, these position specifications have to be made in a reference system that can be transferred to the directions of motion of the machine axes.

  • Page 25 Fundamental Geometrical Principles 2.4 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.

    Fundamental Geometrical Principles 2.4 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.

  • Page 28: Basic Zero System (Bzs)

    Fundamental Geometrical Principles 2.4 Coordinate systems Machine kinematics The workpiece is always programmed in a two or three dimensional, right-angled coordinate system (WCS). However, such workpieces are being programmed ever more frequently on machine tools with rotary axes or linear axes not perpendicular to one another. Kinematic transformation is used to represent coordinates programmed in the workpiece coordinate system (rectangular) in real machine movements.

In other words, the data in the NC program refers to the workpiece coordinate system.

    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.

  • Page 59: Tool Offsets

    Tool offsets General information about the tool offsets Workpiece dimensions are programmed directly (e.g. according to the production drawing). Therefore, tool data such as milling tool diameter, cutting edge position of the turning tool (counterclockwise/clockwise turning tool) and tool length does not have to be taken into consideration when creating the program.

  • Page 60: Tool Radius Compensation

    Tool offsets 6.3 Tool radius compensation This length is measured and entered in the tool compensation memory of the control together with definable wear values. From this data, the control calculates the traversing movements in the infeed direction. Note The offset value for the tool length is dependent upon the spatial orientation of the tool. Tool radius compensation The contour and tool path are not identical.

    Tool offsets 6.4 Tool compensation memory Note Tool radius compensation is applied according to the default CUT2D or CUT2DF (see " 2D tool compensation (CUT2D, CUT2DF) (Page 284) "). References The various options for the tool radius compensation are described in detail in Section "Tool radius compensations".
  • Page 62 Tool offsets 6.4 Tool compensation memory Tool type The tool type (drill, milling or turning tool) determines which geometry data is necessary and how this is taken into account. Cutting edge position The cutting edge position describes the position of the tool tip P in relation to the cutting edge center point S.

    Tool offsets 6.5 Tool types The tool geometry variables consist of several components (geometry, wear). The controller computes the components to a certain dimension (e.g. overall length 1, total radius). The respective overall dimension becomes effective when the compensation memory is activated. How these values are calculated in the axes is determined by the tool type and the current plane (G17/G18/G19).

NOTICE Risk of collision The traversing movement to the retraction position must move away from the fixed stop, otherwise damage to the stop or to the machine may result. The block change takes place when the retraction position has been reached.
  • Page 364 Supplementary commands 15.6 Travel to fixed stop (FXS, FXST, FXSW) The commands for travel to fixed stop can be called from synchronized actions or technology cycles. They can be activated without initiation of a motion, the torque is limited instantaneously. As soon as the axis is moved via a setpoint, the limit stop monitor is activated. Activation from synchronized actions Example: If the expected event ($R1) occurs and travel to fixed stop is not yet running, FXS should be...

  • Page 370: Other Information

    Other information 16.1 Axes In NC technology, the main axes are called geometry axes. This term is also used in this Programming Guide. Replaceable geometry axes The "Replaceable geometry axes" function (see Function Manual, Job Planning) can be used to alter the geometry axes grouping configured using machine data from the part program. Here any geometry axis can be replaced by a channel axis defined as a synchronous special axis.
