The Lathe: Forming and Generating

Question 1

As a form tool is customized to the profile of the part, what does this cause?

Answer 1

Because a form tool is customized to the profile of the part, a single plunge can machine a complex shape.

Question 2

When form tools are on CNC machines, what does this cause? (positive)

Answer 2

On CNC machines, this tooling potentially saves time and increases precision

Question 3

List one positive and negative of form tools

Answer 3

Positive:
On CNC machines, this tooling potentially saves time and increases precision

Negative:
Form tools can be expensive so tend to be used where large quantities of a part are required.

Question 4

What is generating?

Answer 4

This is the use of a single point cutting tool to machine a complex shape

Question 5

What does generating involve? (negatives of it)

Answer 5

It will involve a number of processes such as facing, parallel turning, taper turning and takes much more time than using a formtool
