4. Kinds of coordinate measuring machines According to construction:  Single-coordinate measuring machines – enable to measure only sizes in one axis  Bi-coordinate measuring machines – enable to measure sizes in two perpendicular axis to each other – in one level  3-coordinate measuring machines – enable to measure sizes in 3 perpendicular axis to each other – in space

5. 3-coordinate measuring machines, their arrangement Main measuring device is 3-coordinate measuring machine (CMM – Coordinate Measuring Machine). Measuring machine is characterised by 3 perpendicular axis to each other, called x, y and z. It is the system of: Right-angled coordinates (3-lenght coordinate), cylinder coordinates (2 right-angled coordinates and one rotary axis)

6. Coordinate machine consists of these components:  Measuring machine (main machine unit, measuring bench(table), movable device, measuring and reading system  Computer for measuring process control and for result evaluation  Peripheral machine for data input and output

8. According to constructional component’s arrangement, coordinate measuring machines divide into: Boom machines: Usage :  Heavy engineering  Car industry

9. According to constructional components´ arrangement, coordinate measuring machines divide into: Standing machines: Usage :  Direct measuring in tool making  Precise mechanics

10. According to constructional component’s arrangement, coordinate measuring machines divide into: Portal machines: Usage :  Possibility of big table loading  Reaching small measuring uncertainty

11. According to constructional component’s arrangement, coordinate measuring machines divide into: Bridge machines: Usage :  For big measuring ranges in X-coordinate, e.g. 20000mm x 6000mm x 4000mm

12. Question 1: Describe the type of coordinate machine as you can see in the picture – according to constructional component’s arrangement.

13. Question 2: Describe main components of coordinate measuring machine.
