Recalculate your formula: F=20/(5/45)---F=20/.11111=180.018 The answer is not in inches per minute rather it is in decimal degrees per minute.
Most controller will use the decmial degrees per minute for the rotary move and the inches per minute for the linear move there by coordinating the moves together. This is only true when both a linear move and a rotarty move appear on the same line of code.
The key here is to insure that the G94 mode of your controller accepts this decimal degree mode of operation.
If you would like to discuss this more in depth or have me fax you some data call me a 818 678-2319.
