Sentronics Precision Industry (M) Sdn Bhd – Johor Bahru, Johor

• Develop, optimize, and maintain CNC programs for milling, turning, and multi-axis machining centers using CAM software (e.g., UG/NX, MasterCAM, SolidWorks CAM).
• Define and validate cutting parameters including spindle speed, feed rate, depth of cut, and tool path strategies to achieve optimal machining efficiency and surface quality.
• Create and update process documentation including Standard Operating Procedures (SOPs), process flow charts, and work instructions.
• Lead new product trial runs and first article inspection (FAI) processes, verifying process feasibility and machining accuracy.
• Collaborate with product design teams to provide Design for Manufacturability (DFM) feedback, ensuring product designs are optimized for CNC machining.
• Perform prototype machining and process validation, transitioning new products from development to mass production.
• Provide on-site technical support to production teams, resolving machining issues such as dimensional deviations, surface defects (chatter marks, burrs), tool breakage, and appearance rejects.
• Diagnose and correct machining errors through tool compensation adjustments, program modifications, and parameter optimization.
• Analyze root causes of quality non-conformances and implement corrective and preventive actions (CAPA).
• Select appropriate cutting tools (end mills, inserts, drills, etc.) based on material properties and machining requirements; manage tool life and replacement schedules.
• Design, develop, and validate jigs, fixtures, and work-holding devices to ensure part stability and machining accuracy.
• Conduct tool trials and validation for new tooling solutions to improve performance and reduce costs.
• Drive cycle time reduction initiatives through process optimization, cutting parameter refinement, and machining strategy improvements.
• Monitor and analyze production data (cycle time, yield rate, uptime) to identify bottlenecks and implement improvement measures.
• Lead continuous improvement projects to enhance Overall Equipment Effectiveness (OEE), increase yield, and reduce manufacturing costs.
• Define inspection criteria and measurement methods for machined components.
• Utilize CMM (Coordinate Measuring Machines), surface roughness testers, and other measuring instruments to verify part quality.
• Ensure machined parts meet engineering drawing specifications and GD&T (Geometric Dimensioning and Tolerancing) requirements.
• Support CNC equipment commissioning, setup, and troubleshooting to ensure stable machine operation.
• Collaborate with maintenance teams on equipment preventive maintenance and upgrade initiatives.
• Evaluate and recommend new CNC equipment and technologies to enhance production capabilities.
• Maintain comprehensive records of programs, tooling data, process parameters, and engineering changes.
• Provide technical training and guidance to CNC operators and technicians on machining processes, programming, and safety procedures.
• Ensure all CNC operations comply with company safety, health, and environmental policies.
