Question 11

CNC machine set up procedure prior to component manufacture

Answer 11

• generate an image of the component required on a suitable piece of CAD software.
• select a cutting tool
• select speed of machine
• run a simulation
• choose a material
• convert it to G-code
• set machine to zero axis, turn extractor fan on and check guards.
• start manufacture.
