Kaizen improvement for machine breakdown through why-why analysis and panel wiring VFD

• Perform a why-why analysis to identify the root cause of the breakdown

• Implement kaizen improvement techniques to prevent future breakdowns

• Check the panel wiring and VFD for any faults or issues

• Ensure proper maintenance and regular inspections of the machine

• Train operators and maintenance staff on proper usage and maintenance of the machine

Jig and fixture are tools used in manufacturing to hold and guide workpieces during machining operations.

• Jigs are used to guide cutting tools, while fixtures are used to hold workpieces in place.

• They help ensure accuracy and repeatability in manufacturing processes.

• Examples include drill jigs for guiding drill bits and welding fixtures for holding metal parts in place.

• Jigs and fixtures are commonly used in industries such as automotive, aerospace, and electronics manufacturin...read more

Clearance angle is the angle between the cutting edge and the workpiece during machining.

• Clearance angle allows for the cutting edge to avoid rubbing against the workpiece during machining.

• It helps in reducing friction and heat generation, leading to better surface finish and longer tool life.

• The clearance angle varies depending on the type of material being machined and the cutting tool geometry.

• For example, a larger clearance angle is typically used for softer materials to ...read more

ABS stands for Anti-lock Braking System. It helps prevent wheels from locking up during braking, allowing the driver to maintain steering control.

• ABS uses sensors to monitor wheel speed and prevent skidding

• It works by modulating brake pressure to individual wheels

• ABS is designed to improve vehicle stability and control in emergency braking situations

CNC (Computer Numerical Control) works by using computer software to control the movement of tools and machinery for precision manufacturing.

• CNC machines are programmed using G-code, a language that tells the machine how to move and operate.

• The G-code is generated using CAD/CAM software, which allows for precise design and simulation before production.

• CNC machines can perform a wide range of operations, such as cutting, drilling, milling, and turning, with high accuracy and r...read more
