why do you need to know the specific cutting force for a workpiece material?

Easy to transport mobile concrete plants have axles and tires in its main chassis. Thanks to pre-assembled structure, they can be installed in a very short period of time (1-2 days) View Details

The cutting force signal is simulated for the location of the cutter with respect to the workpiece shown in Fig. 5. This location of the cutter and workpiece corresponds to four pairs of entry–exit angles. The cutting force signal was simulated based on the multiple insert specific cutting pressure constants from Table 6.

I. INTRODUCTION prediction of cutting forces is essential for workpiece obtained from experiments for a specific tool-workpiece pair.

coatings) and workpiece materials require the exact knowledge of the cutting The main values of specific cutting forces were introduced for precision.

Keywords—hard turning, cutting force, cutting tool materials, I. INTRODUCTION high hardness of the workpiece, it results in higher cutting forces 

What are important properties of a workpiece material that can improve machinability? A work material having a low hardness and low work-hardening rate produces small cutting forces and low contact pressure at the tool-chip interface, consequently causing a low temperature rising at the cutting region, hence, shows a good machinability.Low hardness values make a material easier to machine.

Specific Cutting Force (KC1 or KC1.1) Each material has a Specific Cutting Force coefficient that expresses the force in the cutting direction, required to cut a chip area of one square

Mar 21,  · Radial forces tend to push away the tool and account for 10 percent of the cutting forces. The tool's rake controls the degree of cutting forces and power consumption, the strength of the cutting edge, and the direction of chip flow. As a rake angle becomes more negative, cutting forces increase and edge strength improves.

Jan 01,  · The increase in force has an impact on the workload and tool life of the Workpiece-Fixture-Machine Tool-Cutting Tool (WFMC) system. Therefore, in applying the Kienzle and Viktor relationship to calculation of the cutting force, we need to know the change in the specific cutting force (k c1.1 ) and the exponent related to it (z) in cases where a

Workpiece material is brittle or contains hard inclusions and impurities Specific Cutting Force. Ratio of the cutting force to the cross sectional area being cut. How do you increase the cutting force?-Increasing the strength of the workpiece material

Workpiece. Workpiece. Chip. ECE. Ff f fi c i ci on cutting forces had been observed, it should be mentioned.

The tangential cutting force, if end users know how to determine it, and the cutting speed, which is selected as one of several machining 

Our equipment covers the entire unit operation range for aggregate plants. Westpro possesses the industry expertise to combine these products in a modular plant, providing its customers a complete process solution.

It allows you to effectively process a high-quality blank for thick and medium sheet metals. Plasma arc cutting is ideal for the automation of the cutting process. When plasma arc cutting underwater - it creates a very low level of noise and produces a very low heat exposure too. Image of Plasma Cutting torch.

The specific cutting force coefficients depend on the part material and the substrate, coating, rake angle and helix angle of the tool.
