Mastercam Multiaxis Rotary Axis

Mastercam Multiaxis Rotary is a specialized toolpath that generates tool motion along or around the rotary axis of a workpiece. This toolpath is ideal for cylindrical and rotationally symmetrical parts, as well as parts with machining geometry that repeats around an axis. The Rotary toolpath combines the machine’s rotary axis with linear movements, making it possible to produce complex shapes without complicated setup changes. It is especially useful when precision, flexibility, and efficiency are needed for machining parts in which rotary motion plays a central role.

Features

Rotary-axis toolpath: The toolpath can be created along or around the rotary axis of the workpiece. This makes it possible to machine grooves, patterns, and surfaces onto cylindrical parts.
Tool-tip control options: Several options are available, including control, tool wear, and inverse wear. These options control the behavior of the tool relative to the workpiece, providing flexibility for adjusting cutting conditions.
Tool-axis control: The output format is 4-axis, and the user can select the X, Y, or Z axis as the rotary axis. Angular increments, start angles, and sweep angles can also be defined to precisely control the tool’s motion.
Collision checking: Built-in tool-tip control options and consideration of edge surfaces help prevent collisions during machining.
Transitions: Clearance and retract levels, as well as feed levels, can be configured flexibly to ensure safe tool movement around the workpiece.
Safety zones: Protective zones can be created in rectangular, cylindrical, or spherical shapes, helping keep the tool at a safe distance from the workpiece and fixtures.
Roughing and cutting depths: Both absolute and incremental cutting depths can be defined. This supports precise finishing cuts as well as efficient rotary roughing.
Filtering and accuracy: Machining tolerances, compensation types, and chip-control settings enable highly accurate and optimized toolpath calculation.
Directions and strategies: Cutting directions for open and closed profiles can be set to one-way or zigzag, for example.

Applications

Cylindrical parts: Shafts, bars, and tubes that require grooves, shapes, or textures to be machined on their surfaces.
Complex rotary shapes: Curved channels, blade-like forms, and continuously twisted surfaces, for example.
Woodworking and plastic components: Also well suited for router applications that require rotary machining.
Prototype manufacturing: Especially useful for parts with repeating shapes that can be easily produced using rotary motion.

Benefits

Efficiency: Reduces the number of setups and makes it possible to machine multiple surfaces in a single fixturing.
Accuracy and surface finish: Enables consistent, uniform machining around the entire workpiece.
Flexibility: Supports multiple toolpath strategies and allows optimization based on the shape and material of the part.
Safety: Built-in collision checking, safety-zone management, and transition control reduce risks.
Versatility: Can be used for both roughing and finishing and supports many different tool types.

Tips

Use safety zones: Always define safety zones and transition settings to avoid collisions, especially when machining complex parts.
Choose the right tool control: Use tool-wear compensation when you need to account for changes in tool geometry during longer machining operations.
Optimize roughing: Use incremental depth settings to remove large amounts of material.
Use simulation: Always run a simulation before actual machining to verify that the toolpath functions properly and safely.
Machining direction: Choose the zigzag strategy to balance tool load, or the one-way strategy to maximize surface quality.

Summary

The Mastercam Multiaxis Rotary toolpath is a versatile and powerful solution for machining rotationally symmetrical and complex parts. It provides comprehensive tools for chip control, tool control, and safe machining. This rotary-based toolpath reduces the number of setups, improves accuracy and surface quality, and increases programming flexibility. This makes it an excellent choice for both roughing and finishing across a range of industries.
