01Side edge treatment
Compared with using the bottom edge of the tool for machining, using the side edge of the tool for machining can produce a smoother machined surface. Suitable for finish machining of complex cavity parts in the aerospace industry. Mastercam provides dedicated functions to effectively prevent overcutting of the tool and the bottom of the part cavity. It can program side edge machining based on surface or wireframe data, and can choose from several tool types, including tapered tools.
02 Efficient roughing with five-axis connection
Mastercam’s five-axis linkage roughing adopts a fully automatic tool axis control method to avoid drastic changes in the tool axis during the roughing process.
03Use three-axis toolpaths to compile five-axis toolpaths
For some parts, we can first program a three-axis toolpath:
This can then be converted to a five-axis toolpath in Mastercam’s multi-axis module.
The new five-axis toolpath can automatically produce tool axes and re-optimize the original toolpath data, and includes comprehensive five-axis collision detection.
Using “three-axis five-axis” can simplify the difficulty of five-axis programming and increase the programming speed. This function supports the conversion of all three-axis toolpaths, and the generated five-axis toolpaths are fast, safe and reliable, without worrying about overcutting.
04 Automatic tool axis avoidance
When programming in five axes, we often need to consider the interference between the tool axis and the workpiece in the tool path.
When using Mastercam for five-axis programming, we can configure automatic adjustment of the front and side tilt angles of the cutter axis and automatically tilt the cutter axis according to the tolerance specified in the areas where collisions may occur to avoid collisions after cutting; through the collision zone, the tool axis will be automatically adjusted to its original angle to avoid collision between the tool and the workpiece.
In this way, is it easier to program five-axis toolpaths?
05Tool cutting point check
Tool cutting point control can ensure that the tool cutting point is in contact with the workpiece surface without changing any parameters to avoid cutting traps.
Mastercam can control the feed rate between designated areas, designated connections, or segment connections, making the cut tool path through the part smoother.
06Optimizing the distribution of tool path points
The distribution of toolpath points is optimized to control the number of toolpath nodes on each toolpath. Combined with the excellent big data processing capabilities of advanced machine tools, in Mastercam we can increase the number of toolpath nodes in the toolpath and control how the toolpath points are distributed .
Before optimization
After optimization
Increasing the number of cutting nodes in the tool path can make the distribution of tool path points more uniform, make the movement of the tool axis smoother during five-axis machining, and reduce vibration during machining.
This means:
Continued improvement of the quality of the finishing surface;
A stable tool load reduces tool wear;
Stable processing, the machine tool maintains high precision operation.
