Question

For the CMM machine only, write down the followed procedure in sitting the PCS.

Answer 1

A CMM machine is a tool used to calculate the geometric physical properties of an object. This method uses a probe fixed onto the CMM machine's third moving axis, which is used to determine the dimensions of the component in question. Also, a CMM system is used to test and validate a component or assembly and ensure it conforms to the intended specification. The cycle begins by positioning the component or unit on the base of the CMM system which is where the calculation takes place. The base plate is made of a durable material and provides stability and rigidity, ensuring external forces do not disturb the measurement.A movable gantry is placed over a CMM system block, holding a vertical column armed with the measuring probe. The CMM machine will guide the probe along the X, Y and Z-axis, digitally replicating each facet of the fabricated component. When the probe strikes the object, the stylus generates an electrical pulse that is mapped out by computer. This cycle is often repeated to collect thousands of marks, depending on the size of the section.A CMM computer analyzes manufactured parts effectively after weighing them? If the probe is used to catch the component or assembly co-ordinatesX, Y and Z, the detail is processed for function construction. This can also be designed to weigh the same pieces automatically in a repeatable way.

Benefits to Using a CMM Machine:

1. Save time and money
2. Quality assurance is guaranteed
3. Versatile with multiple probes and techniques

Limitations

Sample must hit surface-The instrument used on a CMM system is needed to make direct contact with a surface for a measurement. While this may not be a concern for prototypes and rough sections, this method can potentially affect fragile surfaces. Thankfully, 3ERP continues to reduce this risk due to our comprehensive line of plastic and metal products.

Hard parts may lead to defects If you try to manufacture a piece with oft materials, such as rubbers or elastomers, the probe can allow the surface to cave in as it contacts the component, creating computer   inspection defects.

The best sample needs to be chosen–there are various types of samples that can be used in a CMM system based on the measured component. Once it comes to measuring different interface features and proportions, each stylus provides different functionality. Thankfully, the experienced team at 3ERP will help insure that when put inside a CMM system, the component receives the correct configuration.
