SiM. 5-AxiS MACHining
The sim__axis_1.prz example illustrates the use of the SolidCAM Sim. 5 axis module for turbine blade machining.
The following Sim. 5 axis operations are used to perform the semi-nish and nish machining of the turbine blade:
• Blade Semi-nishing
(X_selected_aces_T1A_1; X_selected_aces_TA_)
The rst operation provides the semi-nish of the turbine blade, using a bull nosed tool of Ø16 with a corner radius of 4 mm. A combination of the Parallel Cuts strategy and Change parallel cuts to spiral option is used to perform the spiral machining of the blade.
The tool tilting is dened using the Tilted relative to cutting direction option, with lag angle of 20°. The tool contact point is dened at the front tool face.
This combination of parameters enables you to perform the machining by the toroidal surface of the tool.
Gouge checking is performed to avoid the possible collisions of the tool with the planar surface of the blade base. The remaining material will be
machined at a later stage, using a special tilting strategy.

The second Sim. 5-axis operation provides semi-nishing of the blade area, close to the blade base. This area was not machined in the previous operation because of the gouge protection. A bull nosed tool of Ø8, with a corner radius of 2 mm, is used for the operation. Similar to the previous operation, a combination of the Parallel Cuts strategy and Change parallel cuts to spiral option is used to perform the spiral machining of the blade.
The tool tilting is dened using the Tilted relative to cutting direction option, with a lag angle of 20°. In addition to the lag angle, a side tilting angle of 10°
is dened to avoid the gouging of the planar face of the blade base.
• Blade nishing (X_selected_aces_TA)
This operation performs the nishing of the blade. A bull nosed tool of Ø8, with a corner radius of 2.5 mm, is used for the operation.
The tool tilting is dened using the Tilted relative to cutting direction option with a lag angle of 20°. In addition to the lag angle, a side tilting angle of 10°
is dened to avoid the gouging of the planar face of the blade base.

SiM. 5-AxiS MACHining
The sim__axis_.prz example illustrates the use of the Sim. 5 axis operation for an aerospace part machining.
A number of Sim. 5 axis operations are dened in order to perform the nish machining of the inclined faces of the aerospace frame and their adjacent llets. The inclined faces are forming an undercut area that cannot be machined using 3 axis milling; we have to use 5 axis milling, with the appropriate tilting strategy, to machine the inclined faces.
• Inclined walls nishing
(X_selected_aces1_T1A; X_selected_aces_T1A;
X_selected_aces_T1A)
These operations perform the nish machining of the inclined walls.
A ball nosed tool of Ø4 is used for the operation.
The Parallel Cutsstrategy is used to generate a number of cuts parallel to the XY plane of the coordinate system.
The tool tilting is dened using the Tilted relative to cutting direction option with a lag angle of 90°. These parameters enable you to perform the
machining with the side face of the tool.

• Fillet machining
(X_selected_aces_T1A; X_selected_aces_T1A;
X_selected_aces_T1A)
These operations perform the nish machining of the llets adjacent to the walls.
A ball nosed tool of Ø4 is used for the operation.
The Project curves strategy is used to generate a single pencil milling pass, machining the llets.
The Tilted through curves tilting strategy is used to perform a smooth transition between different tool axis orientations.

• External Rest Material Roughing (TR_prole_TA)
This operation utilizes the Rest Material option to perform the machining of the areas left unmachined after the previous operation. These areas were unmachined because of the orientation and geometry of the tool used in the previous operation. In this operation a tool with opposite orientation is used to machine the part, moving in the positive Z-direction.
