METHOD OF SETTING HEAT-RESISTANT ALLOY CUTTING CONDITIONS AND METHOD OF CUTTING HEAT-RESISTANT ALLOY
Publication number: 20190224763Abstract: In a method of setting heat-resistant alloy cutting conditions used to set cutting conditions under which a heat-resistant alloy is cut with a cutting tool, the cutting tool has a long shaft mounted on a spindle and extended in the axial direction and teeth formed on the shaft. The cutting conditions include a radial direction cutting amount of the cutting tool in the radial direction. When the radial direction cutting amount in which one tooth is constantly in contact with the heat-resistant alloy is given as a smallest radial direction cutting amount and the radial direction cutting amount in which three or more teeth are not in contact with the heat-resistant alloy is given as a largest radial direction cutting amount, a radial direction cutting amount of the cutting tool is set in the range from the smallest radial direction cutting amount to the largest radial direction cutting amount.Type: ApplicationFiled: July 3, 2017Publication date: July 25, 2019Inventor: Jun ETO -
Publication number: 20190224764Abstract: An attachable and extendable saw and methods for cutting an object on a work surface with the attachable and extendable saw are provided. The extendable saw can include a saw blade housing coupled to a main body by at least one extendable member, the saw blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade housing and the saw blade between a retracted position and an extended position relative to the main body. The extendable saw can also include a motorized unit coupled to the saw blade and configured to rotate or provide other blade movement to the saw blade and a switchable device or unit disposed on the main body and having at least one contact surface that facilitates attachment of the extendable saw to the work surface, said contact surface being switchable between a magnetized or vacuum state and a non-magnetized state or non-vacuum state, respectively. Attachment of the saw blade to the attachable and extendable saw is provided for.Type: ApplicationFiled: February 7, 2019Publication date: July 25, 2019Applicant: Mechanical & Electrical Concepts, Inc.Inventor: Willard D.
