Batch Size given Non-productive Time in Turning Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
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.
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.
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.
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

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)
Non-Productive Time: 28.169 Minute --> 1690.14 Second (Check conversion here)
Loading And Unloading Time: 30 Second --> 30 Second 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

N_b = (t_s+N_t*t_st)/((NPT-t_ln-(t_pt*n₀))) --> (1230+4*600)/((1690.14-30-(90*5)))

Evaluating ... ...

N_b = 2.99965293271853

STEP 3: Convert Result to Output's Unit

2.99965293271853 --> No Conversion Required

FINAL ANSWER

2.99965293271853 ≈ 2.999653 <-- Batch Size

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 Batch Size given Non-productive Time in Turning?

Batch Size given Non-productive Time in Turning calculator uses Batch Size = (Basic Setup Time+Number of Tools Used*Setup Time Per Tool)/((Non-Productive Time-Loading And Unloading Time-(Tool Positioning Time Per Operation*Number of Operations))) to calculate the Batch Size, The Batch Size given Non-productive Time in Turning is the count of similar kinds of products to be manufactured. Batch Size is denoted by N_b symbol.

How to calculate Batch Size given Non-productive Time in Turning using this online calculator? To use this online calculator for Batch Size given Non-productive Time in Turning, enter Basic Setup Time (t_s), Number of Tools Used (N_t), Setup Time Per Tool (t_st), Non-Productive Time (NPT), Loading And Unloading Time (t_ln), Tool Positioning Time Per Operation (t_pt) & Number of Operations (n₀) and hit the calculate button. Here is how the Batch Size given Non-productive Time in Turning calculation can be explained with given input values -> 2.999653 = (1230+4*600)/((1690.14-30-(90*5))).
