Sprutcam integrates 5 continuous axes machining strategies that create the CN code for any type of multi-axis machine. CN code is created taking into account the kinematics of the machine tool that avoids collisions during machining
In five-axis machining process you get simultaneous movement of all five axes of the machine. The key feature of this type of work is that of the cut motion control strategies are used on the surface of the workpiece along with control strategies of tool axis orientation. The strategies of movement of the tool on the surface of the work piece are of various kinds, for example trimming of part a, finishing levels providing the constant value of the height of the crest, movements along or across the curves defined on the surface, movements between the control surfaces, etc. However the axes control occurs through the parameters that allow you to change the inclination of the axis tool during machining and according to certain rules. The easiest way from a programming perspective is the orientation of the axis of the cutter on the rise of the working surface. However, this approach has a number of disadvantages, such as the path often goes beyond the maximum limit of axis movement, other times it is impossible to work the Interior of hand, tool life is short because the cutoff point is always located in a small area, finally cutting speed in the area machined internal axial is much lower than the outside area. It is also difficult to take into account the presence of fixing equipment and of the shape of the tool in order to avoid working inaccessible areas of the part. To resolve these issues SprutCAM uses different strategies for control of cut on the workpiece surface.
Strategies for generating the tool path on the workpiece surface
- Simplified simplified roughing up levels with ramp
- Finish with step defined that supports constant crest height between one coat and the other along the workpiece.
- Cuts in one direction in zigzag or spiral.
- Generation of tool path between the Guide curves.
- Five ACEs along the edge of the profile.
- Generation of 5-axis toolpath projection movements 3 axes.
- Processing of ruled surfaces angled with the side of the cutter.
- Processing of measurement data of the machine in geometry.
Tool axis control strategies
- Lateral and axial tilt angle-independent definitions in direction of movement of the tool.
- Orientation of cutting through a point on the surface, through the curve of the surface or along the curve of the surface.
- Control of the movement of the tool between the corners are defined and maintaining the specified slant that does not affect the processing of the part and does not exceed the limits of the machine.
- Controlling the minimum angle of inclination of the tool, useful in the control of movement that can lead to the collision of the spindle with the part.
- Collision control function automatically changes the tool axis direction prior to the collision. The system pulls the tool from the obstacle of distance set, after the passage of the obstacle the angle of the cutter returned to their previous values.
