general machining guidelines - harvey tool


Machining tapers, chamfers, grooves, and other surface configurations into wheels, roller, and other round parts all fall into the general category of contouring. Tools for grooving the O.D. of hard urethanes 95A to 75D all have the same basic tool geometry.

Machining of Aluminum and Aluminum Alloys

In general, the softer ailoys~and, to a lesser extent, some of the harder al- c loys--are likely to form a built-up edge on the cutting lip of the tool. This edge consists of aluminum particles that have become welded to the tool edge because they were

Good manufacturing practice

Good manufacturing practices (GMP) are the practices required in order to conform to the guidelines recommended by agencies that control the authorization and licensing of the manufacture and sale of food and beverages,[1] cosmetics,[2] pharmaceutical products,[3] dietary supplements,[4] and medical devices.[5] These guidelines provide minimum

Metal cutting knowledge Technical guide from

Metal cutting knowledge Do you need help with calculating starting values, figure out what causes and solves poor tool life or do you need tips on how to optimize your machining processes? When you need an expert's advice for metal cutting, this is the place to go.

Down milling vs. up milling

Down milling In down milling (climb milling), the cutting tool is fed with the direction of rotation. Down milling is always the preferred method wherever the machine tool, fixture and workpiece will allow. In peripheral down milling, the chip thickness will decrease from

Manufacturing Workmanship Standards: Flash at Parting

2019/7/18Once a part is molded and removed from the tool, a technician will either tear or trim the excess material until it's in accordance with our 0.005 in. standard. Flash is a thin layer of excess plastic that flows outside of the mold's cavity and into the parting line, the space between the two mold halves.

General Design Rules for Machining

General design rules for machining (Drilling, Milling Turning) Examples of Drilling Design Guidelines Avoid Deep Holes Entry/Exit Surface for Holes recommended on flat plane surfaces Avoid Holes with Flat Bottom Avoid Holes Intersecting Cavities Partial Holes Standard hole sizes Avoid Deep Holes Deep, small diameter holes should be avoided as they are difficult to machine.

Cutting Speed Chart for Different Materials in Turning,

Machining process: cutting speed for turning, drilling, reaming, and end milling. 3. Please note the table is applicable for high speed steel tooling, when you use carbide tooling, increasing or decreasing the cutting speed based on cutting tool hardness, for example, multiply the listed speeds by a factor of 2 to 4, and the speed should be lower for carbon steel tool.

Tool design Archives

2018/6/25There are many factors that go into determining the running parameters for stainless steel machining, but there are some general guidelines to follow as a starting point. Generally speaking, when machining stainless steels a SFM of between 100-350 is recommended, with a chip load ranging between .0005" for a 1/8" end mill up to .006" for a 1" end mill.

Turning tools

Down milling vs. up milling

In up milling (conventional milling), the feed direction of the cutting tool is opposite to its rotation. The chip thickness starts at zero and increases toward the end of the cut. The cutting edge has to be forced into the cut, creating a rubbing or burnishing effect due to friction, high temperatures and often contact with a work-hardened surface caused by the preceding edge.
