Production Planning And Control

In a product layout the operations are arranged in a sequence according to the production process which allows high volume output and high labour efficiency This layout is ideal for repetitive and high-volume production

Step 1: Understand the mechanisms of material removal in different machining processes.
- Chemical Machining (A) involves material removal by corrosive action (II).
- Electro-Machining (B) involves fusion and vaporization due to electrical energy (I).
- Electro-chemical discharge Machining (C) involves ion displacement (IV), which is due to electrochemical processes.
- Ultrasonic Machining (D) involves erosion by high-frequency vibrations (III).
Step 2: Conclusion The correct matching is:
- (A) Chemical Machining → (II) Corrosive
- (B) Electro-Machining → (I) Fusion and vaporization
- (C) Electro-chemical discharge Machining → (IV) Ion displacement
- (D) Ultrasonic Machining → (III) Erosion
Final Answer:

Step 1: Understand the casting processes.
- Hollow statues are typically made using Slush casting (II), where molten metal is poured into a mold and then slushed out to form hollow objects.
- Dentures are made using Investment casting (IV), a precision casting method often used for small, intricate parts.
- Aluminum alloy pistons are typically produced by Gravity die casting (I), which is suitable for casting metals like aluminum.
- Rocker arms are usually produced by Shell moulding (III), a casting process that provides good surface finish and dimensional accuracy.
Step 2: Conclusion The correct matching is:
- (A) Hollow statues → (II) Slush casting
- (B) Dentures → (IV) Investment casting
- (C) Aluminum alloy pistons → (I) Gravity die casting
- (D) Rocker arms → (III) Shell moulding
Final Answer:

Step 1: Understand the phases of production planning and control.
Production planning and control (PPC) involves various phases like planning, scheduling, and controlling the production processes. Step 2: Identify where order writing fits. - Order writing is part of the planning phase, where production orders are written and prepared to execute production. This phase involves planning for the materials, labor, and machinery required. Step 3: Conclusion Thus, order writing is included in the planning phase. Final Answer:
