5-axis — From curve

00:03

The addition of a 5-axis machine tool to your manufacturing process

00:08

introduces two more rotary axes of control during the machining process.

00:12

The use of 5-axis machining can help you minimize problems associated with multiple setups, poor cutting conditions,

00:20

and interference with the machine or tool that can occur during part manufacturing.

00:25

To help with this, Fusion offers a range of tool axis definition options that can be predefined during the CAM programming process.

00:34

This simplifies your workflows, leading to quicker success.

00:38

A tool axis can be defined so that its orientation is aligned from a curve.

00:43

This method often works well on part shapes where the curve follows the form of the part.

00:49

In this example, consider a bottle mold cavity with a predominantly linear shape.

00:55

Start by examining the Steep and Shallow toolpath, which machines the desired area of the cavity using a vertical tool axis.

01:03

Upon further investigation, you notice an area in the lower region where the tool holder interferes with the part.

01:10

Although you could opt to extend the length of the tool to create clearance,

01:15

this might negatively impact the surface finish and tool wear.

01:19

This is because the cutting conditions would be less than optimum, and tool vibration could be introduced.

01:25

However, you can resolve problems like this, and create better cutting conditions, by defining a different tool axis.

01:33

This allows clearance for the tool holder while maintaining a shorter and more rigid tool length during the machining process.

01:40

Examine the next toolpath and review the Tool Axis settings.

01:45

The Primary Mode is set to From curve and the Guiding Curve is a curve that has been selected at the top of the part.

01:52

In this case, a simple line is being used as the guide curve,

01:56

but complex curve geometry can be used to suit the part shape—all of which are created in the design space

02:02

using Fusion’s intuitive drawing tools.

02:05

These can be modified as needed to drive the intended tool axis.

02:10

When employing this method of Tool Axis definition, the tool axis aligns to the guide curve, resulting in smooth, controlled tool axis motion.

02:20

After simulating this toolpath, verify that the tool now aligns with the curve you have selected as it machines the part,

02:27

creating clearance for the tool holder.

02:29

This approach maintains the shorter tool that is needed for better surface finish quality and tool wear reduction.

02:36

With a proven, easy-to-use library of defined methods of tool axis control,

02:41

Fusion enables you to simply and safely program the rotary axis of your 5-axis machine,

02:47

enhancing your manufacturing success and productivity.
