  1. i have a part which have many island on the surface. when i try milling, i find the MCX keep retracting between chains. and the tool keep going up and down, cutting air. is there any way to avoid the retract actions?? i try to add some points between the chains for guiding the tool not retracting, but MCX seems not smart enough to know what i want it to do.
  2. It's great! i put a 0.01mm gap in the middle of the arc, then the MCXFORSW give me the right chaining result. thank you very much!
  3. thank you. it works fine in MCX. but it doesn't work in MCXforSW. it didn't give me the correct chain. i don't know why, and i can't find the solution.
  4. hi all sorry for my poor english. let me explain more clearly. the process are as below: first of all, i select the left line. mcxFORsw give me a chain1. and then i select the right line. it give me a chain2. it seems everything are just fine. but after i select the arc. something happen. there is no chain3, and the chain2 go away. i had tried select the right line and the arc in the step 2, mxcFORsw give me the same result. ok, then i tried to put the first line in sketch1. and put the right line and arc in sketch2. it's no help. there is still the same result.
  5. I can not find the button of "add another chain", when i chain the toolpath in the sketch. it's easy to chain in the MCX version. but hard to do that in MCX FOR SOLIDWORKS. does any one know how to solve the problem? much thanks! the attache file is mcx9 for solidworks2015. peel.SLDPRT
  6. i just search for the answer of the helix entry mode of CW OR CCW. for now, i am using mastercam x9 for solidworks 2015. the dynamic mill tool always give a cw entry to a pocket. (for example: using 6.0 flat end mill for 3.5 radius entry) but if you choose the helix toolpath (2d circle toolpath), the mastercam will give you a ccw toolpath. so i would like to know, which one of direction entry is better for a flat endmill helix into a solid body. and what's more, in this video, they choose the ccw entry toolpath. if anyone have an idea or some experiences in this, please share with me. thanks!! tom
  7. Hi everyone, I get a sample work to do for milling several slots in a turning part. in my pre thinking, i decide to use 3.0mm flat end mill for rough milling and 1.5mm flat end mill for finish in the toolpath. but after i started, i get no luck. the toolpath seems much more different from what i thought. here are the files attach, can anyone tell me how to solve the problem. thanks!! the version of the file is solidworks 2015 with mastercam x9 Part1.SLDPRT
  8. That is a fantastic skill. thanks very much!
  9. Hi, everybody. I am trying to use mastercam x9 for solidworks (2015) when i want to make contour toolpath (2d high speed is the same), it need me to select the outside boundary for chain. but when the solid body have a chamfer at the outside edge, it's hard to select for chain, because out side edge had been broken to several short lines. i want to know is there any easy way to do the selection? need help, thanks.

  10. Hi, GREG, I think you should change contour mill to Peel Mill. In the peel mill setting, you can increase the feed rate to a higher value, and set the step over value to about 7%(it depends on the material and tools) i post a picture to explain what i mean hope it will be helpful. TOM
  11. I have got 2 very similar toolpath setttings of dynamic rest mill. But the mastercam give me a totally different result of them. it confuse me all day long, i think it's a bug of mastercam X8. T.mcx-8 t2.mcx-8
  12. I have a try of milling C45 steel. Tool: 300R20D20d150L Insert: APMT1135 for steel... (R0.8) Speed: S2500 Feed: 1500mm/min AE: 8% Depth:6mm the result is that, the insert get wearing much faster than i expected(it can't not last for 10 min), and the sounds is very loud. Is insert end mill not suitable for HSM(CHIP THINNING)??? if anyone have a better idea of using the tool, please share with me. much appreciated.
  13. thank you all of above!! i know what i had missed. much appreciation.
  14. contour will leave some material at the four corners. and i think facing will have a better face quality with outside entry toolpath. thank you.
  15. i just mill a part using dynamic core mill. after that, i use facing to mill the rest of the material on the face and the side wall. but i find that facing will over cut the wall side. is there any way to set the check point of facing to avoid that happen? i post a pic and the MCX-7 file to make it easy to understand. any help will be great thankful.
