RISOn the Cause of Regenerative Chatter Due to Workpiece Deflection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cause and the mechanism of regenerative chatter vibrations due to the deflection of workpiece occurring in machining metals are investigated experimentally. The regenerative chatter vibration ...
Static and Dynamic Analysis of Hydraulic Copying System Using Throttling Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of dimension parameters of hydraulic copying control system using throttling valve on the copying accuracy is investigated from two points of view for good design of the system. One ...
Boring by Plug-Type Rotary Cutting Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new boring process is introduced and machining properties are examined. In this process, a drilled hole is finished with a plug-type rotary cutting tool which has a ring-like cutting edge. ...
Damping Capacity of Turning Tools, Part 1: Effect of Clamping Conditions and Optimum Clamping Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Damping capacity greatly affects the dynamic rigidity of a machine tool system. This paper deals with the damping capacity of turning tools. Damping capacity is measured as a function of ...
Damping Capacity of Turning Tools, Part 2: Mechanism Initiating the Damping Capacity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the mechanism initiating the damping capacity of a turning tool. The turning tool is considered as a beam on an elastic foundation. Parameters of the model are estimated ...
Regenerative Chatter Vibration Occurring in Turning With Different Side Cutting Edge Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the regenerative chatter vibration occurring in cutting tools with different side cutting edge angles. The occurrence of regenerative chatter vibration of the cutting tool ...
A Method to Measure Contact Pressure Between Metallic Surfaces by Changes in Surface Roughness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method was developed to find the interface pressure distribution of metallic surfaces in contact by measuring the roughness change. The pressure distribution of two kinds of contact ...
Some Considerations on Characteristics of Static Friction of Machine Tool Slideway
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fundamental characteristics of “stick-slip” motion in a machine tool slideway is ascertained experimentally, and it is clarified that the time-dependence of static friction has a great influence ...
Contact Rigidity at Tool Shank of Turning Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of the contact rigidity between a turning tool shank and tool post. The contact rigidity is influenced by the flexural rigidity of tool shank, ...
Chatter Vibration of Lathe Tools. Part 1: General Characteristics of Chatter Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary chatter vibration of turning tools is investigated experimentally. The vertical displacement of the turning tool and the fluctuating cutting force in the primary chatter vibration are ...
