What feed ratio results when the cross slide moves the tool the same distance as the cross slide feed dial?

• A. 1:1
• B. 2:1
• C. 1:2
• D. 3:1

Answer: (A)

Feed ratio describes how far the tool moves relative to the amount the cross-feed dial indicates per some control input. If the cross slide moves the tool the same distance as the dial shows, you’ve got a one-to-one relationship. In other words, for each unit of dial movement (per revolution of the cross-feed screw), the tool advances exactly that same unit, so the feed ratio is 1:1. If the tool moved more or less than the dial indicates, the ratio would be 2:1 or 1:2, etc., but that isn’t the case here.
