Offset Tables and Setup

Chapter 3

3-8

You can set data in the offset tables by using one of six methods. The
method described here requires that the offset data is manually measured

and then directly keyed into the table. The other five methods are

described in these sections:

Using

{MEASURE}

(page 3-11)

Programming G10s (chapter 20)

Skip functions (chapter 27)

Setting paramacro system parameters (chapter 28)

Altering through the PAL program (refer to the 9/Series CNC PAL
Reference Manual
)

When you use PAL to modify either the work coordinate system
tables or the tool offset tables, tool tip radius compensation should not
be active (G40 mode). If tool tip radius compensation is active, be
aware that the new offset is not placed in part program set-up buffers
that have already been read into control memory. This results in the
offset not being activated until several program blocks after the
current block. The number of setup buffers is dependent on the
number of block retrace steps configured in AMP and what software
features are currently being used.

To manually display or alter the offset tables, follow these directions:

Decide whether you want to display the tool geometry offsets or the

tool wear offsets.

To display:

Press:

the geometry offsets (tool length offsets,

the tool radius, and tool orientation)

{TOOL GEOMET}

softkey. Figure 3.8 shows

examples of tool offset screens.

the wear offsets (tool length and radius

wear data)

{TOOL WEAR}

softkey. Figure 3.8 shows

examples of tool offset screens.
