a heavy duty drill machine operates at 100 rpm per minute. how many times it will rotate in three working shifts given below with in between power cuts of 6 hours 30 min
Answers
Answer:
After completing this unit, you should be able to:
• Describe the Speed, Feed, and Depth of cut.
• Determine the RPM for different materials and diameters.
• Describe the federate for turning.
• Describe the setting speed.
• Describe the setting feed.
To operate any machine efficiently, the machinist must learn the importance of cutting speeds and feeds. A lot of time can be lost if the machines are not set at the proper speed and feeds for the workpiece.
In order to eliminate this time loss, we can, and should, use recommended metal-removal rates that have been researched and tested by steel and cutting-tool manufactures. We can find these cutting speeds and metal removal rates in our appendix or in the Machinery’s Handbook.
Answer:
Describe the Speed, Feed, and Depth of cut.
• Determine the RPM for different materials and diameters.
• Describe the federate for turning.
• Describe the setting speed.
• Describe the setting feed.
