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 is the total time wasted in setting up the machine or workpiece for a particular process.
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 maching.
STEP 1: Convert Input(s) to Base Unit
Non-Productive Time: 20 Minute --> 1200 Second (Check conversion here)
Loading and Unloading Time: 0.5 Minute --> 30 Second (Check conversion here)
Tool Positioning Time per Operation: 1.5 Minute --> 90 Second (Check conversion here)
Number of Operations: 4 --> 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
Nt = ((NPT-tln-(tpt*n0))*Nb-tsa)/tsb --> ((1200-30-(90*4))*3-1230)/600
Evaluating ... ...
Nt = 2
STEP 3: Convert Result to Output's Unit
2 --> No Conversion Required
FINAL ANSWER
2 <-- Number of Tools Used

5 Tool Equations Calculators

Total rate for Machining and Operator
Go Total Rate of Machining and Operator = ((Factor to allow for Machining*Constant for Tool Type(e)*Initial Work Piece Weight^Constant for Tool Type(f))/(2*Amortized Years*Number of Shifts))+(Factor to allow for Operator*Direct Labor Rate)
Tool Changing Time for 1 Tool given Machining Cost for Maximum Power
Go Time to Change One Tool = ((Tool Life*((Machining and Operating Cost of Each Product/Machining Time for Maximum Power)-Machining and Operating Rate)/Time Proportion of Cutting Edge Engagement)-Cost of a Tool)/Machining and Operating Rate
Tool Life for Maximum Power delivery given Machining Cost for Maximum Power
Go Tool Life = Time Proportion of Cutting Edge Engagement*(Machining and Operating Rate*Time to Change One Tool+Cost of a Tool)/((Machining and Operating Cost of Each Product/Machining Time for Maximum Power)-Machining and Operating Rate)
Tool positioning time per operation given Non-productive time in turning
Go Tool Positioning Time per Operation = (Non-Productive Time-((Basic Setup Time+Number of Tools Used*Setup Time per Tool)/Batch Size)-Loading and Unloading Time)/Number of Operations
Number of tools given Non-productive time in turning
Go 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

Batch size given Non-productive time in turning
Go 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)))
Tool positioning time per operation given Non-productive time in turning
Go Tool Positioning Time per Operation = (Non-Productive Time-((Basic Setup Time+Number of Tools Used*Setup Time per Tool)/Batch Size)-Loading and Unloading Time)/Number of Operations
Loading and unloading time given Non-productive time in turning
Go 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)
Set-up Time per tool terms of Non-productive time in turning
Go Setup Time per Tool = ((Non-Productive Time-Loading and Unloading Time-(Tool Positioning Time per Operation*Number of Operations))*Batch Size-Basic Setup Time)/Number of Tools Used
Number of operations given Non-productive time in turning
Go 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
Basic setup time given Non-productive time in turning
Go Basic Setup Time = (Non-Productive Time-Loading and Unloading Time-(Tool Positioning Time per Operation*Number of Operations))*Batch Size-(Number of Tools Used*Setup Time per Tool)
Number of tools given Non-productive time in turning
Go 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
Non-productive time in turning
Go 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*Number of Operations)
Diameter of turned parts given Length-to-diameter Ratio
Go Diameter of Workpiece = (1.67/Length to Diameter Ratio)^(1/0.68)
Length-to-diameter Ratio given diameter of turned parts
Go Length to Diameter Ratio = 1.67/(Diameter of Workpiece^0.68)

Number of tools given Non-productive time in turning Formula

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
Nt = ((NPT-tln-(tpt*n0))*Nb-tsa)/tsb

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.
