Mode Jog - ”Position” operating area

4.1 Mode Jog - ”Position” operating area

Operating sequences

Use the Jog key on the machine control panel to select the Jog mode.

+X ... -Z

To traverse the axes, press the appropriate key of the X or Z axis.

The axes will traverse continuously at the velocity stored in the setting data until the key is released. If the value of the setting data is zero, the value stored in the machine data is used.

If necessary set the velocity using the override switch.

If you press additionally the Rapid traverse override key, the selected axis will be traversed at rapid traverse speed until both keys are released.

In the Jog mode, you can traverse the axes by adjustable increments using the same oper-ating sequence. The set number of increments is displayed in the Status area. To deselect the Jog mode, press Jog once more.

The Jog start screen displays the position, feedrate and spindle values, as well as the cur-rent tool.

Parameters

Table 4-1 Description of the parameters in the JOG start screen

Parameter Explanation

MCS XZ

Displays the axes existing in the machine coordinate system (MCS) or in the workpiece coordinate system (WCS)

+X -Z

If you traverse an axis in the positive (+) or negative (-) direction, a plus or minus sign will appear in the relevant field.

If the axis is already in the required position, no sign is displayed.

Position

mm These fields display the current position of the axes in the MCS or WCS.

REPOS offset If the axes are traversed in the ”Program interrupted” condition in the Jog mode, the distance tra-versed by each axis is displayed referred to the interruption point.

G function Displays important G functions Spindle S

r.p.m. Displays the actual value and the setpoint of the spindle speed Feed F

mm/min Displays the path feedrate actual value and setpoint

Tool Displays the currently active tool with the current edge number

Note

If a second spindle is integrated into the system, the workspindle will be displayed using a smaller font.

The window will always display the data of only one spindle.

The control system displays the spindle data according to the following aspects: The master spindle (large display) is displayed:

− in the idle condition;

− when starting the spindle;

− if both spindles are active.

The workspindle (small display) is displayed:

− when starting the workspindle.

The power bar applies to the spindle currently active.

Softkeys

This softkey is used to set the base work offset or a temporary reference point in the relative coordinate system. After opening, this function can be used to set the base work offset.

Setbase

4.1 Mode Jog - ”Position” operating area

The following subfunctions are provided:

S Direct input of the desired axis position

In the input window, position the input cursor on the desired axis; thereafter, enter the new position. Then, press Input or move the cursor to confirm your input.

S Setting of all axes to zero

The softkey function All to zero overwrites the current position of the appropriate axis with zero.

S Setting Setting of individual axes to zero

Use the X=0 or Z=0 softkey to overwrite the current position with zero.

Use the Set rel softkey to switch the display to the relative coordinate system. Any subse-quent inputs will change the reference point in this coordinate system.

Note

A changed base work offset acts independently of any other work offsets.

Use this softkey to determine the work offset (cf. Chapter 3)

Use this softkey to measure the tool offsets (cf. Chapter 3)

The interactive screenform shown below is intended to set the retraction plane, the safety clearance and the direction of rotation of the spindle for automatically generated part pro-grams in the MDA mode. Furthermore, the values for the JOG feedrate and the variable size of increments can be set.

Retract plane: The Face function retracts the tool to the specified position (Z position) after the function has been executed.

Safety distance: Safety clearance to the workpiece surface

This value defines the minimum distance between the workpiece surface and the workpiece.

It is used by the functions ”Face” and ”Automatic tool gauging”.

JOG feedrate: Feedrate value in the JOG mode

Dir. of rot.: Direction of rotation of the spindle for automatically generated programs in the JOG and MDA modes.

The screenform below is used to store the coordinates of the probe and to set the axis fee-drate for the automatic measuring process (see Section 3.1.5).This only applies to the 802D.

Use this softkey to switch between the metric and the inch system.

4.1.1 Assigning handwheels

Operating sequence

Hand wheel

Use this softkey to display the handwheel window in the Jog mode.

After the window has been opened, all axis identifiers are displayed in the ”Axis” column, which simultaneously appear in the softkey bar.

Select the desired handwheel using the cursor. Thereafter, select the relevant axis softkey for the required axis for assignment or deselection.

The symbol is display in the window.
