    Milling with Robots

    Yes, for large plastic part trimming. But when I was involved with this it was long before there were any useful offline programming solutions like RobotMaster or Octopuz. All of the paths were created with the teach pendant or via direct coordinate input. Robots can repeat processes very consistently, so once you have a process dialed in you are good to go which works great from long run or repeat run parts. To get to the point of a good part will more than likely take several iterations as the toolpaths will need to be moved around a bit, but this would be the same if you were using a 5 axis router as you are dealing with large plastic parts on fixtures that are often times less than perfect. The time it takes to get to a proven process will no doubt be faster with a 5 axis router. With Robots you can think outside the box a little too. Your fixtures can be more creative to allow better access to more "sides" of the part. Many robots can be mounted horizontally, upside down, or on a linear rail to expand the work envelope or deal with limited ceiling heights/work envelopes. HTH

    G60 and Fanuc 0i-MC Control

    sounds familiar with similar results. There was one place where they used to remove the 4th axis that was mounted on one end of the table every time a specific job was run so they could make parts in spec! I hate it when the real world and the laws of physics get in the way of making good parts... using a single axis approach definitely has it's place and can make a big difference, and it can be done manually if you don't have G60.

    G60 and Fanuc 0i-MC Control

    What is our machine model and age? Have you done any testing to see if this improves accuracy on your machine? I had setup a custom drill cycle to do this manually for an old clapped out machine and it made a real difference. Being that rapid moves are all exact stop mode I'm just curious if you are seeing any tangible benefits.

    Machining approach

    The only way axis substitution would work is if the tool diameter is the same as the slot width. Assuming you want to use a smaller too so you can have rough and finish passes, and you want to use the side of the tool, you are looking at Rolldie, Curve 5 axis, Swarf, Swarf Milling, and Ruled. The Multiaxis Parallel and Morph toolpaths would work as well, but they both add complexity to get what you are looking for. HTH
  5. I would recommend using the predefined variable tap_pitch$ as it will be correct for both inch and metric. HTH

    Create curve on one edge with section views

    this was discussed in great detail during the initial testing of section views. It was set to be looked into for a future release.

    Coolant Commands

    if you want want to output multiple M codes on one line you can define it like this: sm09 : "M09 M31 M31" or If you want to output multiple M codes on separate lines define it like this: sm09 : "M09" + no2asc(13) + "M31" + no2asc(13) + "M31" ASCII character 13 is a carriage return HTH

    Verify O-ring cutters.

    you can create an .ini file for verify that goes into the program files/mcam2019 folder that will enable verify to show "O-ring" or "trepanning" tools. This will slow down verify so I would recommend removing it when you are done. I don't have the specifics of the .ini file in front of me. I'm sure your dealer can help otherwise I can dig into more later this afternoon. HTH

    Vertical Mill 5 axis contour tool path using Y and C axis

    I'm not sure you are looking for axis substitution. axis substitution is for when your tool is perpendicular to the rotary axis. Is that what you are looking for? Axis substitution is not typically supported by 5 axis posts but can be implemented. if you are looking for your tool to be parallel with the axis of rotation Mastercam has this function on the rotary axis tab that will use the C axis. this functionality may be supported by your 5 axis posts, if not it can be implemented. if neither of these apply maybe post a pick of your part in backplot so we can get a better idea of what you are looking for.

  10. Importing Manual Entry Toolpaths work great. We do have a number of people that use our Strategy Manager to speed up the process of importing Manual Entry Toolpaths for setup info, header info, mfg instructions, probing cycles, etc... HTH

    adjust feed-rate on curve 5 axis

    after you launch the toolpath editor you should just be able to click on a vector like in the screen shot below: HTH

    adjust feed-rate on curve 5 axis

    You can actually select the point via the graphics area, you just need to click the vector before hitting edit point. but using the up/down arrow to define the point works too. HTH

    adjust feed-rate on curve 5 axis

    the Toolpath Editor will allow you to edit the feedrate. right click on the toolpath and you will find it at the bottom of the right mouse button menu HTH

    Mass Modify Xform Tool Paths

    While not the same as mass modifying multiple Transform toolpaths at once you CAN drag & drop the parameters from one transform to another. When you drag & drop the parameters it sets all parameters except which toolpaths are selected, but you can do some testing to confirm you are getting the results you need. HTH

    Advice

    Mits makes good stuff, but you will find those who swear by Mits, ISCAR, Kennametal, Ingersol, SECO, Sandvik, etc... And they are all speaking the truth for what they do on their equipment. Insert technology (geometry, coatings, chip breakers, etc...) changes extremely rapidly, what was cutting edge a short time ago is now old news. I would suggest you have all of the mfg's you know provide good service and maintain local stock in your area to come in and do a presentation, do several cuts on your machines with different materials you cut, and provide a comprehensive price list of the holders and inserts for the materials you work with. When doing the cuts keep exact data and video each cut to compare later. I know we all want the best cutters and you normally get what you pay for, but if your equipment doesn't have the horsepower or rigidity to take advantage of some of the cutters you may find a less expensive option makes more sense for your company HTH
