Jeremy, until v 9.1 comes out try adding a vertical move, using the graphical toolpath editor, between the first line of lead in where the cutter comps and the arc move of lead in. Same applies for lead out move. If your control can handle it this will accomplish the exact same thing as what v9.1 will do. Steve

Jack, Hello my fellow Canadian, why not modify the post so it prompts a question to the programmer half way through post processing regarding the size or type of chuck being used. If he/she (programmer) inputs a certain size/type the post would limit the spindle RPM to a value low enough that it forces the operator to manually edit the "S" value in the program (in the case of the 4 jaw chuck). Keep the poetry coming, it's priceless. Steve

Rekd, To get rid of the G80 in your custom "Tool Stop" cycle, edit your pcanceldc postblock to look like this: pcanceldc #Cancel canned drill cycle result = newfs (three, zinc) z = initht if cuttype = one, prv_zia = initht + (rotdia/two) else, prv_zia = initht pxyzcout !zabs, !zinc prv_gcode = zero pcan if gcode >= 8, pcan2 else, pcan1, pbld, n, "G80", strcantext, e pcan2 This is for a standard MpFan post but it might give you an idea of where to look if you have a different post.

Connormac, Open up your post processor in Cimco or whatever editor your using. The directory for your post editable file is probably C:Mill9MillPosts(your post name).pst. Run a search for the postblock called pdrlcst or scroll through until you find a bunch of code that looks like this: pdrlcst #Custom drill cycles 8 - 19 (user option) #Use this postblock to customize drilling cycles 8 - 19 pdrlcommonb "CUSTOMIZABLE DRILL CYCLE ", pfxout, pfyout, pfzout, pfcout, e pcom_movea Change the line that starts with "CUSTOMIZABLE DRILL CYCLE" to read n, "M00", e and it should look like the following: pdrlcst #Custom drill cycles 8 - 19 (user option) #Use this postblock to customize drilling cycles 8 - 19 pdrlcommonb n, "M00", e pcom_movea This should get you what your after and if it doesn't post the result on the forum and I'll help you out. Steve

Connormac, An honest question with good intentions is never a stupid one. Post a sample of code on the forum and some of the changes you'd like and I'm sure you'll get more than one response on how to go about fixing your problem. Like Trevor said, try contacting your local dealer about this. CNC Software and In House Solutions releases how to information about editing post processors so you might want to ask your dealer about something like that as well. Good Luck, Steve

connormac, how much experience do you have editing post processors. If you do, one possibility would be to customize your post so that an M00 would be output on any toolpath when misc integer 4 (for example) was set to 1. In your post you could have a conditional branching line that runs a custom postblock that would output an M00 with a spindle orient or no rotation if mi4 was greater than zero. Just an idea. Steve

The only help I can offer is to check that the surface normals are pointing to the side you want the fillet on. Surface filleting won't work if one of the normals is "flipped" in the wrong direction and they can be changed under Analyze, Surface, Set Norms.

Hi Andy, If you're looking to create counterbores with very little load on the tool, I've found that using a threadmill toolpath works well for roughing this kind of feature. Setting the pitch around .01" for this instance allows you to get away with feed rights considerably higher than you might expect. Also the tool load is constant through out the entire cut and chip evacuation isn't as much of a problem than having the cutter buried to full depth and taking all cuts radially. Good luck, Steve
