or extrude the shaft and put the chamfer on it then extrude a hex and add it as a boss
-
It uses the original part origin as the location when cooordinates are given - open the pattern file by itself and look at the origin - when a location is given when bringing in a pattern the part origin goes to that location so the part may not be where you want it
-
Create a surface at the depth of the holes create another surface with the holes cut out at the top of the part- a flat boundry - and use the surface at the depth of the holes as the drive surface and the flat boundry as a check surface
-
OOPS should have been parallel to the Z axis
-
Dont know why but if you rotate the part so that the small end is parallel to the y axis the gouge moves to the other end ie; the end that is not parallel to the y axis gouges when the path is generated creating some other geometry it turns out that the greater the angle from the axis the bigger the gouge
-
I think all the quick paths do is simplify your toolpath menus by eliminating some of the toolpath choices - if you look at quick finish for example the plunge parameters are missing
-
I have used the pink foam like Colin suggested with very good results - it holds pretty good size can be measured and will not damage tools if they crash into it
-
Opening a metric part when in English config changes my Mcam to metric config - I thought one of the options used to be to scale the part to English w/o Mcam reverting to Metric config Mcam now goes to metric config - and must be set back to English at which point it will ask to scale the part - is there a setting to avoid resetting to Metric when importing a file
-
A 3-d contour
-
Sorry guys I started in Metric config and switched to English It will not use 3 places in Metric and even though I switched to English it did not reset the calculations parameters until I restarted Mcam
-
Probably a setting I cant find X2 Mill will give only .0001 feed rate when caculating from material if feed per tooth is a 3 place decimal ie .004 but it will calculate correctly when using a 2 place decimal ie .04 I looked in machine def under axis feed limits and it is set to allow 500 ipm max

Warning construction plane perpendicular to graphics view
JDowe replied to Robert Critelli's topic in Industrial Forum
Change the graphics view to match the construction plane - or set graphics view to isometric -
Import the part as a parasolid - make sure the the centerline is at 0 on the top c-plane create stock using the stock option in the properties section of the group create toolpath using the solids option at the top of the chaining box set use stock for outer boundry in the rough parameters page
-
look on the rool die page for slot
-
Also right click in the operations manager and select doc file to get tools and offsets only - set up sheet in operations manager gives feeds and travels etc.

If I understand your I thinkpart what you want is curve 5 axis in Mastercam
-
Probably right in front of me but dont see how to insert a pause in a Macro to allow entry of infromation such as dimensions Thanks for help
-
Can you just create one and do a rotate 1deg copy 359 times from the right c plane or maybe I dont understand the part
-
In rotary 4th axis toolpath if you check "use center point" it will keep the tool axis pointed at the center of rotation
-
In sorting try turning off filter out duplicates
-
another possibility Create a revolved surface Create curve flowline on the surface as many lines as you want create point segment on each of the resulting curves - using distance between - to keep all bumps from from being in a line rotate every other curve 180 before points then create primative spheres at each point Also I have soccer ball geometry if you want
-
Since the distance around the large end of tne cone is greater than around the small end - the geometry must be adjusted to compensate for this also the geometry to be rolled must be at an angle to the centerline of the cone to compensate for rolling at a different the different diameters
-
Look at a socker ball and check out the patches Create a spherical surface calculate the size of a patch on the surface create the patch above the sphere Use a c-hook called grid pock to create points on the patch project thes points onto the surface create spheres on these points rotate and copy these around the center of your original sphere - it will take several copies and rotations - figuring the rotation angles is a bit tedious - and it is can be trickey to get the bumps equally spaced if you look at a golf ball they are not
-
Have you tried a 3-d chamfer using a lollipop tool - it seemed to work for me - I have an example to e-mail if you want
-
If you create a line multi and type coordinates ie: x1y2 x3y1 x4y2 you will get a line from x1y2 to x3y1 to x4y2 etc. if you only give it one value for x or y it will draw a horizontal or vertical line using the previous x or y value - you must have default fast point mode ste in autocursor for this to work
