Materials can be manufactured using wasting techniques such as cutting using scissors, shears or saws.
Materials can be manufactured using wasting techniques such as drilling.
Risk assessments identify potential risks and list actions to be taken to minimise these.

Cutting is the only form of removing material.

Removing material can include cutting, drilling and the use of abrasive papers and tools.

Wasting - removing material
Quantity - the number
Risk assessment - a way of assessing the potential dangers and planning to minimise these
Abrasion - removal of surface material by friction
