Number of Tools given Non-Productive Time in Turning Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Number of Tools Used - The Number of Tools Used is the total number of tools used for manufacturing a batch of products.
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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

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
Batch Size: 3 --> No Conversion Required
Basic Setup Time: 20.5 Minute --> 1230 Second (Check conversion here)
Setup Time Per Tool: 10 Minute --> 600 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_t = ((NPT-t_ln-(t_pt*n₀))*N_b-t_s)/t_st --> ((1690.14-30-(90*5))*3-1230)/600

Evaluating ... ...

N_t = 4.0007

STEP 3: Convert Result to Output's Unit

4.0007 --> No Conversion Required

FINAL ANSWER

4.0007 <-- Number of Tools Used

(Calculation completed in 00.004 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 Number of Tools given Non-Productive Time in Turning?

Number of Tools given Non-Productive Time in Turning calculator uses Number of Tools Used = ((Non-Productive Time-Loading And Unloading Time-(Tool Positioning Time Per Operation*Number of Operations))*Batch Size-Basic Setup Time)/Setup Time Per Tool to calculate the Number of Tools Used, The Number of Tools given Non-Productive Time in Turning is the total number of tools used for manufacturing a batch of products. Number of Tools Used is denoted by N_t symbol.

How to calculate Number of Tools given Non-Productive Time in Turning using this online calculator? To use this online calculator for Number of Tools given Non-Productive Time in Turning, enter Non-Productive Time (NPT), Loading And Unloading Time (t_ln), Tool Positioning Time Per Operation (t_pt), Number of Operations (n₀), Batch Size (N_b), Basic Setup Time (t_s) & Setup Time Per Tool (t_st) and hit the calculate button. Here is how the Number of Tools given Non-Productive Time in Turning calculation can be explained with given input values -> 4.0007 = ((1690.14-30-(90*5))*3-1230)/600.
