Shafts
The times are calculated based on the core Costimator speeds, feeds for machining, machine and material specifications.
User Input
1. The Stock Size is the original diameter of the bar or cutoff blank that will be machined.
2. The Stock Length is the overall length of the part to start with.
3. Enter the "1st Dia. Size". This is the final size of this outside diameter of the part.
ALL DIAMETERS ARE SELECTED FROM THE LARGEST TO THE SMALLEST. The reason for this is so the program accurately calculates the time for a particular diameter based on the stock removal required from the last selected diameter.
4. Enter the "Length". This is the length of the diameter you just selected.
If there are more diameters on the part, then continue on. There are (5) diameters to select from. If you need more than simply complete this model and then call it up again and continue on.
5. Enter the "1st Thread Dia.". This is the major diameter of the thread.
6. Enter the "Pitch". This is the number of threads per inch.
7. Enter the "Length" of the thread.
The program will calculate the number of passes required as well as the machining times.
Included with the thread is an undercut, since most threads on round parts require that. Continue selecting other thread sizes until you're done. If you need more, simply save these entries and call up this model again.
8. Enter the "1st "O" Ring Dia.".
The time will calculated based on average depth of this feature.
9. Enter the "Spline Length" if your part has splines on it.
10. Enter the "Number of Teeth" on the Spline.
All of the calculations for producing the spline are done in the background.
The total time represents a sum of those features you selected only.
