1.1 Basics

Tools for the B axis

Another advantage of the B axis is that it allows flexible use of the

tools during turning operations. By tilting the B axis and rotating the

tool you can bring it into positions that enable you to use one and the

same tool to machine in the longitudinal and transverse (or radial and

axial) directions on the main and opposing spindles.

In this way, you need fewer tools and fewer tool changes.

Tool data: All tools are described in the tool database by specifying

the X, Z and Y dimensions as well as the compensation values. These

dimensions are referenced to the tilt angle B=0°.

Another parameter that is maintained in the tool database is the

position angle. It defines the working positions of tools that are not

driven tools (turning tools).

The tilt angle of the B axis is not maintained with the tool data. This

angle needs to be defined in the tool call or when inserting the tool.

Tool orientation and position display: For turning tools, the position

the tool tip is calculated based on the orientation of the cutting edge.

This orientation is not regenerated automatically when the B axis is

tilted and/or rotated.

When the B axis has been moved manually, the control marks the

position display invalid.

 Display with black digits: Position display is valid.

 Display with gray digits: Position display is invalid.

After moving the B axis, please check whether the orientation is still

valid and reassign it, if necessary.

When orienting tools, the control distinguishes between roughing,

finishing and button tools as well as recessing and threading tools (see

figure).

 Tool positions 1, 3, 5 or 7 apply to roughing, finishing and button

tools. The control recognizes neutral tools by the tool angle.

 Tool positions 2, 4, 6 or 8 apply to recessing and threading tools.

Whether the tool is a “right-hand” or a “left-hand” tool is defined in

the tool data.

Machine display: The T box in the machine display indicates the

tool's pocket in the magazine. The current tilt angle of the B axis is

taken into account in the compensation values shown in this box.
