Alpine Metal Works AG is a manufacturer of precision metal components based in Zurich, Switzerland. Around 200 people are employed at the plant, which suppl...

(a) Automation is the use of machines or computer-controlled equipment [1] to perform tasks that were previously done by human workers, with little or no human involvement in the process. [1]

(b) Two ways Alpine Metal Works AG could use CAD/CAM in its production process:

1. CAD for component design [1] - Engineers could use CAD software to design new precision metal components on screen, testing and modifying designs digitally before any physical production begins. This reduces costly errors by identifying problems before materials are cut or shaped. [1]
2. CAM for automated manufacturing [1] - CAM software converts the CAD design directly into instructions that control the manufacturing machinery, producing components with greater precision and consistency than manual cutting and shaping methods. [1]

(c) Three advantages to Alpine Metal Works AG of introducing automation to its production line:

1. Improved consistency and quality [1] - Robotic arms and computer-controlled machinery do not become tired, unlike human workers. The case study notes that defect rates rise during the final hour of each shift due to worker fatigue. [1] Automation would eliminate this problem, producing consistently precise components throughout the entire production cycle, which is especially important for safety-critical automotive and aerospace parts. [1]
2. Lower long-term unit costs [1] - Automated machinery can operate continuously without needing breaks, and does not require wages, overtime pay or employee benefits. [1] Over time, the reduction in labour costs per unit would improve Alpine Metal Works AG's profit margins and make it more competitive when bidding for contracts with automotive and aerospace clients. [1]
3. Increased output and productivity [1] - Automated production lines typically operate faster and for longer hours than manual labour. [1] This increased capacity would help Alpine Metal Works AG meet growing demand from its clients and potentially take on larger contracts, supporting the growth of a business with CHF 30 million in annual sales. [1]

(d) Alpine Metal Works AG should invest in the CHF 4 million automation programme. The investment represents approximately 13% of annual sales revenue (CHF 4 million out of CHF 30 million), which is significant but manageable for an established manufacturer. The clear quality benefits are especially important given that Alpine supplies safety-critical aerospace and automotive components, where precision is essential and defects can have serious consequences. [1-2]

However, the company must manage the staff concerns carefully. The senior engineers already support the plan, which is a positive sign. For the long-serving machine operators who are worried about job losses, Alpine should develop a retraining programme so existing workers can learn to operate, maintain and programme the new robotic and CAD/CAM systems. This retains valuable institutional knowledge while moving the workforce to higher-skilled roles. [1-2]

The main risk is the upfront cost and potential disruption during the transition period. Alpine should consider phasing the installation to minimise production downtime, starting with the most repetitive assembly tasks where the quality improvement will be greatest. [1]
