Realizing high levels of efficiency in your subtractive manufacturing might be easier than you think with High Speed Milling. This new Creo extension includes a pile of features that enhance your mold and die work and production parts.
The HSM milling module simplifies and improves 5-axis programming, making it easy to create simultaneous 5-axis and 3+2 axis collision-free toolpaths. These can be used for both mold & Die and production parts. The extension complements your existing 5-axis Creo toolpaths, and they work on full B-Rep solid geometry as well and faceted and imported tessellated objects (repetitive polygonal features).
The toolpath algorithm automatically check for the maximum rest machining area and selects the largest area to be machined along the Z axis. It also selects the tool direction with the best access. After that, it machines the area, then repeats until the stop condition set by the user is met.
Features and specifications
Auto 3+2 axis roughing - the HSM can detect machining directions with minimum orientations. It includes automatic collision checking with the in-process stock, as well as the part itself. This even works with complex parts that have undercut areas. All the system requires is the tool definition and the stock/part definition as input surfaces.
5 axis roughing - the HSN includes high speed roughing for continuous 5-axis machining of pockets with curved floor surfaces. This high level of automation mirrors 3+2 axis machining in that it works with minimal inputs and does collision checking.
Convert 3-axis to 5-axis finish toolpath - forget the painstaking manual conversion of 3-axis toolpaths to 5-axis toolpaths. The HSM extension will do that for you. The main reason for 5-axis is to user shorter tools, resulting in a toolpath that is fully collision checked, and to avoid the chatter and deflections that tend to happen with longer milling tools.
HSM Finish and Rest Finish options - HSM Finish and Rest Finish toolpaths can accurately finish complex parts while keeping a high surface quality. This feature is designed for high-speed finishing with smooth cutting and linking passes. This capability comes with a host of finishing options, including:
Constant Z for steep areas
Constant cusp for milling shallow areas
Smartcut, which is a combination of constant Z and constant cusp
Multi pencil for rest finish for cornering
Auto deburring toolpaths - the deburring options in HSM have evolved: instead of manually defining trajectory toolpaths to do deburring, now the edges are automatically detected, along with auto tilting, linking, and collision checking. This automatic detection significantly cuts the setup time, too, it saves time during manufacturing and reduces the amount of training needed to get employee up to speed. To use the automated edge detection, the reference model is required. Once this is set, you can define which edges you want deburred, the minimal length of edges that should be detected, and the edges by minimum edge angle.
