What are the various cost associated with machining ?
The various costs associated with machining process are:
(i) the manpower cost, Cl which is measured in per unit time, generally hours that operator is employed
(ii) the machine tool operating (overhead) cost, Cm which includes machine depreciation, and other costs associated with the running of the machine tool such as power con summed, maintenance overheads, consumables such as oils, etc. This may also include the other overhead costs, which takes care of all the fixed overheads such as buildings, land and administrative overheads.
(iii) the job handling cost, which arises because of the time spent in loading and unloading of the job, during which time the machine tool is kept idle, and also requires the operator to attend to the job. It is also possible that some special equipment such as crane, etc. may be used for heavy jobs.
(iv) the tool cost, Ct which is the cost of the cutting tool for the given operation.
How to Calculate Machining Time given Cutting Speed?
Machining Time given Cutting Speed calculator uses Machining Time = (pi*Workpiece Diameter*Length of Bar)/(Feed Rate*Cutting Velocity) to calculate the Machining Time, Machining Time given Cutting Speed is defined as the time required to complete a particular machining operation. Machining Time is denoted by t symbol.
How to calculate Machining Time given Cutting Speed using this online calculator? To use this online calculator for Machining Time given Cutting Speed, enter Workpiece Diameter (D), Length of Bar (L), Feed Rate (f) & Cutting Velocity (V) and hit the calculate button. Here is how the Machining Time given Cutting Speed calculation can be explained with given input values -> 1.137705 = (pi*0.01014*3)/(0.0007*120).
