Made a discovery last week regarding cutting 3 Axis parts in HSM. I don’t know if Scallop cutting was in there before as I don’t remember it so in any case new to me and it was the missing link for my parts. Up until now I had kept ST7 and CAMWorks for Solid Edge on one of my workstations because I liked the Constant Stepover tool path so much. While fiddling around and looking at aspects of HSM I had not really investigated before I discover that HSM has this same capability. Scallop judging by the tool paths does the exact same thing as Constant Stepover in that it has a true constant stepover in X Y and Z simultaneously. There is no better cut path for fine surface finishes on complex parts than this.
Regarding this video. It is from A to Z again and all steps are there from importing the file done in Solid Edge through creating a cam plan in HSM and then tool path simulation. Keep in mind this was done on a four year old Dell T3500 workstation and there is talking and time fiddling compared to an individual just sitting down and doing it. My point basically is that it does not take long to do this part from begining to end in less than optimal conditions. The video is 17 + minutes and with a fast workstation and someone who knew the program and was not fiddling around I bet this would take less than 12 minutes from beginning to end.
One comment made in the video about comments made earlier in the video make no sense. What I meant was to reference stock to leave and smoothing and to leave them blank.You can reference the blog post before this one for a detailed explanation. https://solidedging.wordpress.com/2015/07/14/inventor-hsm-2016-accuracy-tip/
As an aside here. The Autodesk guys are pretty closed mouthed about what is going on with HSM. It is looking like this year is when it will all come together for HSM and as little bits dribble out you can tell they are excited. It is about time. Solid Edge has an 18 month cycle for each version from absolute beginning to RTM and this is with experienced staff on a product they have years of experience with. The HSM guys have had a ton of stuff on their plates including integration with two new programs along with some sort of upcoming core change and finishing up leftovers like the Hole Wizard. In addition they have had to find new talent to hire and then get them up to speed so they can make worth while contributions. I am not at all surprised it has taken this long but I do believe the wait will be over later this year. And it will be well worth the wait.
I now have all the tools for a cut that will require no hand finishing for food extrusion dies. It is remarkable to me just how fast and simple cutting parts can be when you are using the right program.
As an aside here some thoughts on software. In some regards I am an abnormal CADCAM user. I am a self employed small business owner and most users are not. I have an interest in my software tools beyond most including many owners who just want things to work now. I want to know the mind set of the authoring company and it’s leaders. I want to know where they are heading so I can relate their products to my future plans. Most users are cubical dudes I figure and their interest is only in the paycheck they earn, quitting time or perhaps how to sneak way to much social media into the mix and get a paycheck doing it. No interest with software and certainly not what makes it tick. I am part of an even more abnormal group and that is as a blogger who does not get paid for what he does and there are darned few of us left. I talk about what I use and what interests me or makes me mad. But this abnormal state of mind is where I want to be. It had stopped being fun over at SE a year ago January when I decided Siemens was determined to bury SE and became bleak after Karsten Newbury was run off. There are not many happy people there any more. Today talking to the Autodesk guys is like it used to be with SE. It is refreshing to deal once again with people who have confidence in their corporate leadership, the direction they are heading and believe in the products they work on.
