Material-removal systems, cutting tools therefor, and related methods
Embodiments described herein relate to material-removal systems as well as cutting tools and cutting tool assemblies that may be used in the material-removal systems. More specifically, for example, the material-removal systems, and particularly the cutting tools, may engage and fail target material. In some instances, the material-removal systems may be used in mining operations.
1. A method of replacing one or more cutting tools on a cutting tool assembly, the method comprising:
providing a base body having a surface mountable to a cutterhead of a material-removal machine and one or more tool positioning features each of which includes at least a base body channel at least partially defined by two opposing channel sidewalls and a channel bottom;
removing an initial cutting tool from the base body channel of one of the one or more tool positioning features of the base body;
positioning at least a portion of a positioning feature of a cutting tool in the base body channel of the one of the one or more tool positioning features, the positioning feature and the one or more tool positioning features being sized and configured to orient a tool body of the cutting tool, wherein the cutting tool includes a superhard table defining a working surface; and
securing a first clamping member to the base body with a first sidewall of opposing sidewalls of the first clamping member being adjacent to an upper portion of a first sidewall of opposing sidewalls of the tool body of the cutting tool, wherein the opposing sidewalls of the first clamping member define an acute angle therebetween that is inverted relative to an acute angle defined by the opposing sidewalls of the tool body of the cutting tool.
2. The method of claim 1 , further comprising securing a second clamping member to the base body with a first sidewall of opposing sidewalls of the second clamping member being adjacent to an upper portion of a second sidewall of the opposing sidewalls of the tool body of the cutting tool, wherein the opposing sidewalls of the second clamping member define an acute angle therebetween that is inverted relative to the acute angle defined by the opposing sidewalls of the tool body of the cutting tool.
3. The method of claim 2 , wherein:
securing a first clamping member to the base body with a first sidewall of opposing sidewalls of the first clamping member being adjacent to an upper portion of a first sidewall of opposing sidewalls of the tool body of the cutting tool includes securing the first clamping member to the base body with the first sidewall of the opposing sidewalls of the first clamping member contacting to the upper portion of the first sidewall of the opposing sidewalls of the tool body of the cutting tool; and
securing a second clamping member to the base body with a first sidewall of opposing sidewalls of the second clamping member being adjacent to an upper portion of a second sidewall of the opposing sidewalls of the tool body of the cutting tool includes securing the second clamping member to the base body with the first sidewall of opposing sidewalls of the second clamping member being adjacent to the upper portion of the second sidewall of the opposing sidewalls of the tool body of the cutting tool.
4. The method of claim 3 , wherein:
the base body channel extends through the base body between two upper surfaces of a plurality of upper surfaces on a periphery of the base body;
securing the first clamping member to the base body includes securing the first clamping member to a first upper surface of the two upper surfaces; and
securing the second clamping member to the base body includes securing the second clamping member to a second upper surface of the two upper surfaces.
5. The method of claim 1 , further comprising positioning a protrusion in the base body channel of the base body in a tool body channel of the tool body of the cutting element.
6. The method of claim 1 , wherein securing a first clamping member to the base body with a first sidewall of opposing sidewalls of the first clamping member being adjacent to an upper portion of a first sidewall of opposing sidewalls of the tool body of the cutting tool includes removably securing the first clamping member to the base body with a fastener.
7. The method of claim 1 , wherein positioning at least a portion of a positioning feature of a cutting tool in the base body channel of one of the one or more tool positioning features includes positioning the cutting tool on the base body along a generally curved path.
8. The method of claim 1 , wherein the at least a portion of the position feature is positioned in the base body channel and the first clamping member is secured to the base body without removing the base body from a cutterhead of a material removal system.
9. The method of claim 1 , further comprising removing an initial cutting tool from the base body channel of the one of the one more tool positioning features on the base body before positioning the at least a portion of the positioning feature of the cutting tool in the base body.
10. The method of claim 9 , further comprising selecting the cutting tool to replace the initial cutting tool based on a property of a target material for the cutting tool assembly.
11. The method of claim 10 , wherein the initial cutting tool is configured to engage or fail harder material than the cutting tool.
12. A method of replacing one or more cutting tools on a cutting tool assembly, the method comprising:
providing a moveable and/or rotatable cutterhead and one or more cutting tool assemblies mounted to the cutterhead, each of the one or more cutting tool assemblies including a base body mounted to the cutterhead and having one or more tool positioning features each of which includes at least a base body channel at least partially defined by two opposing channel sidewalls and a channel bottom;
removing an initial cutting tool from the base body channel of one of the one or more tool positioning features of the base body
positioning at least a portion of a positioning feature of a cutting tool in the base body channel of the one of the one or more tool positioning features, the positioning feature and the one or more tool positioning features being sized and configured to orient a tool body of the cutting tool, wherein the cutting tool includes a superhard table defining a working surface; and
securing a first clamping member to the base body with a first sidewall of opposing sidewalls of the first clamping member being adjacent to an upper portion of a first sidewall of opposing sidewalls of the tool body of the cutting tool, wherein the opposing sidewalls of the first clamping member define an acute angle therebetween that is inverted relative to an acute angle defined by the opposing sidewalls of the tool body of the cutting tool.
13. The method of claim 12 , further comprising securing a second clamping member to the base body with a first sidewall of opposing sidewalls of the second clamping member being adjacent to an upper portion of a second sidewall of the opposing sidewalls of the tool body of the cutting tool, wherein the opposing sidewalls of the second clamping member define an acute angle therebetween that is inverted relative to the acute angle defined by the opposing sidewalls of the tool body of the cutting tool,
wherein the at least a portion of the positioning feature is positioned in the base body channel and the first clamping member and the second clamping member are secured to the base body without removing the base body from the cutterhead.
