Loading and Unloading Time given Non-productive Time in Turning Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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.
Number of Operations - The Number of Operations is defined as the total number of operations done in a batch.

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
Tool Positioning Time Per Operation: 1.5 Minute --> 90 Second (Check conversion here)
Number of Operations: 5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_ln = NPT-((t_s+N_t*t_st)/N_b)-(t_pt*n₀) --> 1690.14-((1230+4*600)/3)-(90*5)

Evaluating ... ...

t_ln = 30.1400000000001

STEP 3: Convert Result to Output's Unit

30.1400000000001 Second --> No Conversion Required

FINAL ANSWER

30.1400000000001 ≈ 30.14 Second <-- Loading And Unloading Time

(Calculation completed in 00.035 seconds)

What is the difference between turning and facing operations?

In the turning operation, the tool generally reduces the diameter of the cylindrical workpiece, which can be done by cutting into the part for some depth and move the tool parallel to the axis of the part. While facing operation reduces the length of the piece, the tool is moved perpendicular to the axis of the part.

How to Calculate Loading and Unloading Time given Non-productive Time in Turning?

Loading and Unloading Time given Non-productive Time in Turning calculator uses Loading And Unloading Time = Non-Productive Time-((Basic Setup Time+Number of Tools Used*Setup Time Per Tool)/Batch Size)-(Tool Positioning Time Per Operation*Number of Operations) to calculate the Loading And Unloading Time, The Loading and Unloading Time given Non-productive Time in Turning is the time required to load/unload the workpiece before the start of machine operation. Loading And Unloading Time is denoted by t_ln symbol.

How to calculate Loading and Unloading Time given Non-productive Time in Turning using this online calculator? To use this online calculator for Loading and Unloading Time given Non-productive Time in Turning, enter Non-Productive Time (NPT), Basic Setup Time (t_s), Number of Tools Used (N_t), Setup Time Per Tool (t_st), Batch Size (N_b), Tool Positioning Time Per Operation (t_pt) & Number of Operations (n₀) and hit the calculate button. Here is how the Loading and Unloading Time given Non-productive Time in Turning calculation can be explained with given input values -> 0.008372 = 1690.14-((1230+4*600)/3)-(90*5).
