Number of Operations given Non-productive Time in Turning Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Operations = (Non-Productive Time-((Basic Setup Time+Number of Tools Used*Setup Time Per Tool)/Batch Size)-Loading And Unloading Time)/Tool Positioning Time Per Operation
n₀ = (NPT-((t_s+N_t*t_st)/N_b)-t_ln)/t_pt
This formula uses 8 Variables

Variables Used

Number of Operations - The Number of Operations is defined as the total number of operations done in a batch.
Non-Productive Time - (Measured in Second) - Non-Productive Time (NPT) refers to the time during which a machine is not actively engaged in producing parts.
Basic Setup Time - (Measured in Second) - Basic Setup Time is the basic time required to load/unload the workpiece and position the tool for production for one component.
Number of Tools Used - The Number of Tools Used is the total number of tools used for manufacturing a batch of products.
Setup Time Per Tool - (Measured in Second) - Setup Time Per Tool is defined as the amount of time taken in setting up the tool while machining.
Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
Loading And Unloading Time - (Measured in Second) - Loading And Unloading Time is the time required to load/unload the workpiece before the start of machine operation.
Tool Positioning Time Per Operation - (Measured in Second) - Tool Positioning Time Per Operation is defined as the time taken in changing the tool before the start of operation.

STEP 1: Convert Input(s) to Base Unit

Non-Productive Time: 28.169 Minute --> 1690.14 Second (Check conversion here)
Basic Setup Time: 20.5 Minute --> 1230 Second (Check conversion here)
Number of Tools Used: 4 --> No Conversion Required
Setup Time Per Tool: 10 Minute --> 600 Second (Check conversion here)
Batch Size: 3 --> No Conversion Required
Loading And Unloading Time: 30 Second --> 30 Second No Conversion Required
Tool Positioning Time Per Operation: 1.5 Minute --> 90 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n₀ = (NPT-((t_s+N_t*t_st)/N_b)-t_ln)/t_pt --> (1690.14-((1230+4*600)/3)-30)/90

Evaluating ... ...

n₀ = 5.00155555555556

STEP 3: Convert Result to Output's Unit

5.00155555555556 --> No Conversion Required

FINAL ANSWER

5.00155555555556 ≈ 5.001556 <-- Number of Operations
