Two separate workpieces are to have a taper cut with the same taper per inch, using the offset tailstock method. After the first piece is completed, the tailstock offset must be changed if there is a change in the __________.
• tailstock offset method for turning tapers on a lathe • definition of taper per inch (change in diameter per unit length) • geometric relationship between offset, work length between centers, and the taper angle
• If the taper per inch must stay the same, which factor actually changes the angle between the workpiece centerline and the lathe bed? • Think about a long vs. a short workpiece: with the same sideways offset, would the taper per inch be identical for both lengths? Why or why not? • Does simply changing the cutting tool angle or starting diameter automatically change the taper made by the tailstock offset method?
• Be clear on what taper per inch measures: ( \Delta \text{diameter} / \text{length} ). • Recall that tailstock offset creates a small angle over the distance between centers; check how that angle depends on length. • Verify which option, if changed, would require a new offset to keep the same taper per inch.
