Five axis machining programming fun and interesting gameplay

Five-axis machining refers to x, y, z three axes of movement plus any two axes of rotation. Compared with the most common three-axis (x, y, z three degrees of freedom) machining, five-axis machining is usually used for machining geometrically complex parts, it requires the tool to be able to freely position and connect in the five degrees of freedom.

The machine tool used in five-axis machining is usually called five-axis machine tool or five-axis machining center. In the manufacturing industry, five-axis machining is usually applied to the aerospace field, it can be processed with free-form surface of body parts, turbine parts and impeller. The five-axis machine tool can process the different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts.

So, what are the fun and interesting ways of five-axis machining in Mastercam?

Side cutting

The surface of the workpiece produced by using the side edge of the tool is smoother than that produced by using the bottom edge of the tool. This machining method is especially suitable for machining complex cavity workpiece in the aerospace industry. And Mastercam also provides special functions, it can effectively prevent the tool and the bottom of the part cavity overcutting phenomenon, but also according to the surface or wire frame data side edge machining programming, available tools including conical knives and other types.

Five axis linkage efficient opening

The five-axis linkage opening of Mastercam adopts automatic tool shaft control mode, which can avoid drastic changes of tool shaft in the process of opening and roughing.

Use three - axis cutter path to make five - axis cutter path

When programming some special workpiece, we can first make up a three-axis cutter path according to the idea of three-axis programming:

We then convert the three-axis cutter path to the five-axis cutter path automatically in a function of the multi-axis module that comes with Mastercam.

The newly generated five-axis tool path can automatically generate the tool shaft and optimize the original tool path data at the same time, and also includes a complete five-axis collision detection.

Through flexible application of the function of "three axes to five axes", not only can greatly simplify the difficulty of five-axis programming, but also greatly improve the programming speed. This functional module supports the transformation of all three-axis cutter paths, and the five-axis cutter paths generated at the same time are safe, reliable and fast, and there is no worry about cutting.

Automatic tool shaft avoidance

In the five axis programming, we can not avoid a problem is the tool path in the tool axis and the workpiece interference.

If we use Mastercam for five-axis programming, we can automatically adjust the forward and roll Angle of the tool shaft according to the actual situation, so that the tool path can automatically tilt the tool shaft according to the specified tolerance in the area where there may be collision, avoiding collision; After leaving the collision area, the tool shaft can be automatically adjusted back to the original set Angle, so as to completely avoid the collision between the tool and the workpiece.

Starting from the three-axis cutter road to change the five-axis cutter road, such a change does not feel that the programming of the five-axis cutter road is not difficult?

Tool cutting point control

The control of tool cutting point can ensure the contact between tool cutting point and part surface without changing any existing parameters, so as to avoid cutting traps.

And the Mastercam can control the feed speed between the specified area, the specified connection or the section connection, the ultimate purpose is to make the cutter path cut into the workpiece, can be more smooth.

Tool path point distribution optimization

Tool path point distribution optimization, this function can precisely control the number of tool nodes on each tool path. By combining the excellent big data processing ability of precision machine tools, we can increase the number of cutting node in the tool path and control the distribution of cutting point in Mastercam.

By increasing the number of tool nodes in the tool path, the distribution of tool path points can be more uniform, so that the movement of the tool shaft in the five-axis machining process is smoother, and the vibration in the machining process can be reduced.
