Mill-turn Machining

Algorithm of preparing NC program for lathe-milling processing center is similar for other types machines, but it has some features. This features will be described in current part.

First of all, a machine is chosen, on which a treatment will be processing. CAM system can program several types of lathe-milling processing center, which have fundamental differences in structure, including Swiss lathes machines.
If a machine is supply with a machining turret for it a setup tooling is forming.
After this describe a processing of part, workpiece and fixtures and its fixing mode. You can define several parts in one project, see Multi part projects for more.
Next the point of tool interchange is determined.
After that different operations may be created, both turning and milling so long as the billet will be manufactured. For getting an objective view in simulation mode, while setting a cutting tool it is necessary to set holder and overhang.
Some turning machines do not support standard cycle of processing holes during work with the driving tool. In this case it is necessary to use Hole machining operation with the expanded style of toolpath. This operation may generate standard cycles in expanded state.
If machine had not equipment with Y axis, a polar interpolation may be used for face plane milling.
For milling on cylinder surface by radial tools a cylinder interpolation may be used.
If detail has repeating elements, this way advisability to use that possibilities of the system as multiplication around an axis.
After calculation of every operation a trajectory is checking for a correctness in simulation mode.
Before finally generation of NC program it is necessarily to check operations parameters in summary table.

Check an accuracy in setting numbers of tools. System doesn't control if in different operations various tools set on the same numbers.
Necessarily to check turning tools point in all operations. With wrong turning point simulation works correctly, but NC-program is generate with serious slip which can bring to tool fracture or even machine breakage.
Switch to control condition of cutting mode, check direction of spindle rotation, heat-removing and correctness of feeding values.
After any settings changing and recalculating make sure in absence of exclamation marks.
