Rotary Calc

5 Axis Rotation Calculator

You have a CAD model of a part which you want to mill a face that is at a compound angle.

You can position a part so that any face that is at a compound angle is up by making two rotations of the part. This will compensate for any number of compound angles on the part.

Whether you are using a five axis rotary table, or using a 4th axis rotary table and locating the part at a certain angle before the rotation, or are building a single fixture to hold the part at an angle, you can compensate for any number of compound angles and put the face up for milling just by calculating the two necessary rotations.

But it can be confusing on how figure which angles to use. This calculator makes it easier.

All you need to do is make a line perpendicular to the surface you want to mill.

How to do it

If you are milling a face you need to draw a line perpendicular to the face.	If you are drilling holes at a compound angle you can make a line from the bottom to top of the hole.

The result page will show what angles to move.

Inplot Tips
Most of the editor utilities operate on a selected block if any is selected, otherwise it starts operating from the cursor line to the end of file.

You can mirror the NC code by using the Switch XYZ dialog, but it's better if you can rotate it 180 degrees because then all the cuts will be going the same way instead of reverse.

You can shorten up some programs by using the Order NC utility to strip unneeded addresses. It checks for redundant values and deletes them.

You can put the name of the Cadl CAD file of the part in the program with the CDL Comment Code. This will automatically load the CAD file when you run the program.

You can Pan the CAD window by dragging with the middle mouse button, or by holding down the left mouse button and the control key.

You can dynamically rotate the view in the CAD window (when in a view other than top view) by holding down the Alt key and dragging with the left mouse button.

You can download the latest updates to the Inplot software at any time from the www.i-logic.com web site.

You can undo the last changes in the editor with Ctrl-Z

There are alternate Find and Replace Dialogs available with Cntl-F and Cntl-R keys.

You can stop the tool animation with Esc and get the coordinates at that point and insert them into the editor.

You can Merge other files into the editor at the cursor position by Dragging them from the File Explorer with holding down the Alt key

The last plotted move will flash on and off if 'Flash Path Element' is checked in Config-Screen

The default drawing depth in the views can be set by a right mouse click on the View Buttons.
