Complex programming example
Description:
A more complex program (shaft) is to be programmed, by using the tech-
nology "Straight Circle".
Aim:
The workpiece shown in the graphic below is to be programmed.
Afterwards the program is to be simulated.
The following tool and technology data are used for the programming.
Tool data: Finishing tool 55° (FINISHING_TOOL_55)
Technology data: Raw material: Ø 105 x 102 mm
Firstly there is a planar cut to Z = 0.
Then the step Ø 90 x 60 mm is machined with one
cut.
Finally follows the machining of the finished diameter
including the machining of the chamfer 3x45° and
the radius R5.
