QUALITY ASSURANCE
Quality is controlled through defined inspection and measurement activities across the manufacturing
process. The company maintains incoming, in-process and final inspection controls appropriate to the
products and customer requirements.
DMM
Height Gauge
DVC
DMM – Digital Multimeter
A Digital Multimeter is an electronic measuring instrument used to check:
- Voltage (V) – AC/DC voltage
- Current (A) – electrical current
- Resistance (Ω) – resistance of components
- Continuity – whether an electrical connection is complete
- Diodes – basic diode testing
Height Gauge
A height gauge is normally used on a surface plate. The workpiece is placed on the plate, and the measuring probe or scriber is moved vertically to measure the required dimension.
Basic process:
Surface Plate → Place Component → Set Reference Zero → Move Measuring Probe → Take Height Measurement → Record Inspection Result
In CNC and precision manufacturing, a height gauge can be used to check:
- Hole center height
- Step height
- Component thickness/height
- Slot position
- Distance between features
- Overall component dimensions
DVC
In CNC machining and manufacturing, DVC can refer to different things depending on the equipment or inspection document. If you're seeing it in a quality-control or measurement equipment list, I’d need the exact context to give you the correct expansion.
Air Gauge
The air gauge uses compressed air that flows through a precision nozzle into or around the component. Changes in the air pressure or flow indicate the dimensional variation of the component.
Basic Process:
Compressed Air → Air Gauge → Component → Pressure/Flow Measurement → Dimension Verification
In CNC machining and automotive component inspection, air gauges are commonly used for:
- Bore diameter measurement
- Outside diameter measurement
- Taper checking
- Roundness and cylindricity inspection
- High-accuracy dimensional inspection
Testing & Inspection
Hardness Testing
Evaluates the material’s resistance to indentation, wear, and deformation to ensure durability and performance.
Tensile Strength Testing
Measures the material’s ability to withstand pulling forces and determines its strength and elongation properties.
Torque Testing
Verifies the fastening performance by measuring the torque required for tightening, loosening, or failure.
Salt Spray Testing
Assesses corrosion resistance by exposing components to a controlled salt mist environment.
Other Specialized Tests
Assesses corrosion resistance by exposing components to a controlled salt mist environment.
