If the cutting tool is not tightly clamped in the tool post it could move when a cut is taken.
This can result in the tool penetrating the workpiece as the cut progresses causing an undersized workpiece. It can also eventually bite into the workpiece and possibly cause damage to the workpiece, the lathe, the cutting tool and even injury to the machinist and others in close proximity.
An American style tool post is a square tool post designed for a center lathe. It can be rotated, is square and dove-tailed on all four sides. The dove tails allow tool holders with cutting tools clamped in it to be inserted and locked in place. This style of tool post decreases production time due to its ease of function and preset tool center heights.
the types of tool post on lathes can be classified as single screw tool post four bolt tool post open side tool post four way tool post
tool post is used to handle the tool on the lathe machine
If you are using a 45 degree tool there's no need to set the tool post and you can just cut it by feeding the cross slide. If you are physically going to cut a chamfer with the compact slide, then you should set your tool post to 45 degrees.
The basics procedure used for turning a bushing on lathe are:Material is inserted and tightened into the chuck so it protrudes about 10mm over the actual length of the final bushing lengthIf the material is not hollow bar, a drill is inserted into the tail stock then the material is drilled to enable the a boring bar to fit the holeA roughing tool is inserted into the tool post then the face of the workpiece is machined smooth and the outside diameter to about 0.5mm oversizeA roughing boring bar is inserted into the tool post and the inside diameter is machined to roughly 0.5mm undersizeA finishing tool is then inserted into the tool post then first the face and then the outside diameter of the workpiece is machined to the required sizeAt this point a finishing boring bar is inserted into the tool post and the inside diameter is machined to the required sizeChamfer tools are then used to chamfer both outside and inside edges at the faceThe parting tool is inserted into the tool post then the bushing is parted off about 0.5mm to 1mm longer than specified.The remainder of the material is removed from the chuck then the parted bushing is inserted and tightened with the unfinished side protruding about 5mm to 10 mm.A finishing tool is inserted into the tool post then the face is machined to the required sizeChamfer tools are then used to chamfer both outside and inside edges at the faceThe above method is just a basic explanation of how the operation is achieved. Operating a lathe without proper training is not recommended and could lead to serious injury!
The jig could be worn or damaged or it might not be clamped or secured tightly. It is also possible that the tool was not held tightly against it. It depends on the jig.

When grinding, an abrasive material such as carborundum is used to remove material from the workpiece. When turning, material is removed from the workpiece with a cutting tool. The worpiece is usually clamped in the jaws of a chuck, and the chuck turns. the tool is clamped to a toolpost and moved along the workpiece and into the workpiece in order to cut material off in a measured amount.
The tool post allows the user to control a cutting tool (such as a chisel) more accurately - to produce better results. The tool post holds the lathe tools that will be required for each cutting operation required in that part of teh production process. Each post can hold up to four differing tolls - example. Facing tool, knurling tool, long reach internal cutter and then a parting tool. The tool post rides on the saddle on a horizontal plane and the in a cross feed. Most tool feeds can be set to automatic where cutting speed is set and the movement of the post on the saddle automated
This is the place to close on the lathe cutting tool.

It's not necessary at all. But the fact that it can be usedas a navigational tool makes it quite useful.
All chisels, saws and awls are usually very sharp.
The tool roll is used to compactly carry common tools needed to perform a task. All the necessary tools are kept within sleeves built into a flat, wide case and rolled up tightly. When the tools are needed, it is simply unrolled and all the tools are visible and ready to be used.
