Programming a straight line

The tool moves at the programmed feedrate or with rapid traverse from its actual position to

the programmed end position.

Radius compensation

Alternatively, you can implement the straight line with radius compensation. The radius

compensation acts modally, therefore you must deactivate the radius compensation again

when you want to traverse without radius compensation. Where several straight line blocks

with radius compensation are programmed sequentially, you may only select radius

compensation in the first program block.

When executing the first path motion with radius compensation, the tool traverses without

compensation at the starting point and with compensation at the end point. This means that if

a vertical path is programmed, the tool traverses an oblique path. The compensation is not

applied over the entire traversing path until the second programmed path motion with radius

compensation is executed. The reverse effect occurs when radius compensation is

deactivated.

Press the "Tool list" and "New tool" softkeys.

Using the softkeys on the vertical softkey bar, select the required tool and

press the "To program" softkey.

The tool is copied into the "T" parameter field.

Select the tool cutting edge number D if the tool has several cutting edges.

Enter the spindle speed or cutting rate.

Enter an allowance in the "DR" field.

Press the "Accept" softkey.

The values are saved and the parameterization screen form is closed.

The process plan is displayed and the newly generated program block is
