1.4 Pocket calculator

This function can be activated for all input fields intended for entry of numerical

values by means of the “=” character. To calculate the required value, you can

use the four basic arithmetic operations, and the functions sine, cosine,

squaring, as well as the square root function. If the input field is already loaded with a value, this function writes the value in

the input line of the pocket calculator.

The calculation is carried out when the Input key is pressed. The function

writes the result to the input field and automatically closes the pocket

calculator. To calculate auxiliary points on a contour, the pocket calculator provides the

following functions:

line moving a point in a plane

These functions are directly linked with the input fields of the programming

support. Any values in this input field are written by the pocket calculator into

the input line, and the result is automatically copied into the input fields of the

programming support.

Softkeys

This function is used to calculate a point on a circle. The point results from the

angle of the created tangent and the direction of rotation of the circle.

Fig.1-4 calculation of a point on a circle Enter the circle center, the angle of the tangent and the radius of the circle. Use the softkeys G2 / G3 to define the direction of rotation of the circle.

The values of abscissa and ordinate are calculated. The abscissa is the first

axis of the plane, and the ordinate the second axis of the plane.

Example

If plane G17 is active, the abscissa is the X axis, and the ordinate the Y axis. The value of the abscissa is copied into that input field from which the pocket

calculator function has been called, and the ordinate value into the next

following input field.

Introduction

1.5 Basic principles

Coordinate system

Fig.1-8 Specification of mutual relationship between axis directions

Machine coordinate system (MCS)

Right-handed, rectangular coordinate systems are used for machine tools.

Such systems describe the movements on the machine as a relative motion

between tool and workpiece.

The orientation of the coordinate system on the machine tool depends on the

particular machine type. It can be turned to various positions.

Fig.1-9 Example of machine coordinates/axes The origin of the coordinate system is the machine zero. All axes are in zero position at this point. This point is merely a reference point

determined by the machine manufacturer. It needs not to be approachable. The traversing range of the machine axes can be negative.

Introduction

Workpiece coordInate system (WCS)

The definition of the directions is based on the assumption that the workpiece

The workpiece coordinate system described above (see Fi g. 1–8) is also used

to describe the geometry of a workpiece in the workpiece program.

The workpiece zero can be freely selected by the programmer. The programmer

need not know the real movement conditions on the machine, i.e. whether the

workpiece or the tool moves; this can be different in the individual axes.

The use of the programmable zero offset provides a completely new current

To machine the workpiece, it is clamped on the m ach ine. Th e workpi ece must

determined for each axis and entered into the intended data areas for the

by means, for example, of a programmable G54 (see Section “Workpiece

Note

Before you switch on the SINUMERIK and the machines, you should also have

read the machine documentation, since turning on and reference point

approach are machine-dependent functions.

Operating sequence

First switch on the power supply of the CNC and of the machine. After the

control system has booted, you are in the “Machine” operating area, in the Jog

operating mode. The Reference point approach window is active.

Fig.2-1 Jog Ref basic screen

Reference-point approach can only be executed in the Jog mode.

Activate the “Approach reference point” function by selecting the Ref key on

the machine control panel area. In the “Reference point approach” window (Fig. 2–1), it is displayed whether or

not the axes have to be referenced.

3.1.3 Determining the tool offsets

Functionality

Prerequisite

This function can be used to determine the unknown geometry of a tool T.

The appropriate tool has been changed. In JOG mode, approach a point on the

machine, from which you know the machine coordinates, with the edge of the

tool. This can be a workpiece with a known position. The machine coordinate

value can be split into two components: stored zero offset and offset.

Procedure

Enter the offset value in the intended Offset field. Then select the required zero

offset (e.g. G54) or G500 if no zero offset is to be calculated. These entries

must be made for each selected axis (see Fig. 3-5).

Please note the following: For milling tools, length 1 and the radius must be

determined, and for drilling tools only length 1. Using the actual position of point F (machine coordinate), the offset entry and

the selected zero offset Gxx (position of the edge), the control system can

calculate the assigned compensation value of length 1 or the tool radius.

Note:

You can also use a zero offset already determined (e.g. G54 value) as the known machine coordinate. In this case, approach the workpiece zero with the edge of the tool. If the edge stands directly at the workpiece zero, the offset value is zero.

Prerequisite

You have selected the window with the corresponding zero offset (e.g. G54) and the axis for which you want to determine the offset.

Approach

A zero offset can only be determined with a known (entered geometry)

and active tool. Enter the active tool in the dialog box. Press OK to take over the tool; the Determine window is then opened.

The selected axis appears in the Axis area.

The actual position of the tool support reference point (MCS) associated

to the axis is displayed in the adjacent field. D number 1 is displayed for the tool edge.

If you have entered the valid offsets for the used tool under a D number other than D1, enter that D number here.

The stored tool type is displayed automatically.

The effective length compensation value (geometry) is displayed.

Select the sign (-, +) for calculating the length offset, or select “without”

taking the length offset into account. A negative sign subtracts the length offset value from the actual position.

If the tool can neither reach, nor “scrape” the desired position, an offset

value can be entered in the Offset field. Approach the coordinates of the intended workpiece zero offset (if

necessary with consideration of the entered offset value) in JOG mode. The resulting zero offset is determined from the actual position and all

active compensation values by means of the Calculate function.

• RTS/CTS The RTS signal ( Request to Send) controls the send operation of the data transmission device. Aktive signal: Send data Passive signal: Do not exit send mode until all transferred data have been sent. The CTS signal is the acknowledgment signal for RTS and indicates that the data transmission device is ready to send.

XON This is the character that is used to start transmission.

It is effective only for device type XON/XOFF.

XOFF This is the character with which data transmission is

stopped.

End of transmission This is the character that signals end of transmission

of a text file. The special function “Stop with end of transmission” character may not be active if binary data are to be transferred.

Parity Parity bits are used to detect errors. These are added

to the coded character in order to obtain either an even or odd number of positions set to “1” . Input: No parity (default) Even parity Odd parity

Servo trace

To optimize the drives, an oscillograph function is provided for graphical representation of the velocity setpoint. The velocity setpoint corresponds to the ±10V interface.

The start of recording can be linked with various criteria which permit recording

in parallel to internal conditions of the control system. The setting needed for this option must be carried out in the “Select Signal” function.

The following functions can be used to analyze the result:

Change scaling of abscissa and ordinate,

Measure value by means of a horizontal or vertical marker,

Measure the abscissa and ordinate values as a difference between two

marker positions.

This function branches to another softkey level, in which the horizontal or vertical marker can be switched on or off. The markers are displayed in the status bar.

Larger step widths can be set in the input fields. The value specifies the number of raster units per <SHIFT> + cursor movement by which the marker is to be moved.

If a marker reaches the margin of the diagram, the next raster in horizontal or
