Step 1
Which ONE of the following is an advantage of the tailstock set-over method for taper turning on the centre lathe?
Answer
The advantage of the tailstock set-over method for taper turning is that it allows for more accurate and adjustable tapers to be produced. Specifically, option B states that internal tapers can be cut, which is a significant advantage over other methods.
Step 2
Step 3
Which indexing process using the universal dividing head will be the easiest method to cut a gear with 30 teeth?
Answer
The easiest indexing process to cut a gear with 30 teeth would be 'Simple indexing' (Option B). This method simplifies the calculation and allows for quick setup and operation.
Step 4
What is meant by the term incremental programming on a three-axis digital read-out system on a computer numeric control (CNC) machine?
Answer
Incremental programming refers to a method where each movement is defined concerning the last position, often starting from a reference point such as the 'zero point' (Option B). This allows for greater flexibility and accuracy in machining operations.
