Access to the preset table was simplified. There are also new possibilities for entering values in the preset table. (see “Manually saving the datums in the preset table” on page 85).

In inch-programs, the function M136 (feed rate in 0.1 inch/rev) can no longer be combined with the FU function.

The feed-rate potentiometers of the HR 420 are no longer switched over automatically when the handwheel is selected. The selection is made via soft key on the handwheel. In addition, the pop-up window for the active handwheel was made smaller, in order to improve the view of the display beneath it (see “Potentiometer settings” on page 75).

The maximum number of contour elements for SL cycles was increased to 8192, so that much more complex contours can be machined (see “SL cycles” on page 396).

FN16: F-PRINT: The maximum number of Q-parameter values that can be output per line in the format description file was increased to 32 (Conversational Programming User's Manual).

The soft keys START and START SINGLE BLOCK in the Program Test mode of operation were switched, so that the soft-key alignment is the same in all modes of operation (Programming and Editing, smarT.NC, Test) (see “Running a program test” on page 585)

The design of the soft keys was revised completely.

16

Changed functions with 340 49x-03

In Cycle 22 you can now define a tool name also for the coarse roughing tool (see “ROTATION (Cycle G122)” on page 405).

When running programs in which non-controlled axes are programmed, the TNC now interrupts the program run and displays a menu for returning to the programmed position (see “Programming of noncontrolled axes (counter axes)” on page 589).

The tool usage file now also includes the total machining time, which serves as the basis for the progress display in percent in the Program Run, Full Sequence mode (see “Tool usage test” on page 595).

The TNC now also takes the dwell time into account when calculating the machining time in the Test Run mode (see “Measuring the machining time” on page 581).

Arcs that are not programmed in the active working plane can now also be run as spatial arcs (see “Circular path G02/G03/G05 around circle center I, J” on page 235).

The EDIT OFF/ON soft key on the pocket table can be deactivated by the machine tool builder (see “Pocket table for tool changer” on page 202).

The additional status display has been revised. The following improvements have been introduced (see “Additional status displays” on page 55):

A new overview page with the most important status displays were introduced.

The individual status pages are now displayed as tabs (as in smarT.NC). The individual tabs can be selected with the Page soft keys or with the mouse.

The current run time of the program is shown in percent by a progress bar.

The tolerance values set in Cycle 32 are displayed.

Active global program settings are displayed, provided that this software option was enabled.
